It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
An application scenario of an embodiment relates to playing of a dynamic picture, and includes a publishing page of the dynamic picture, a list page of the dynamic picture, a preview interface of the dynamic picture, a detail page of the dynamic picture, and the like.
As shown in fig. 1, in one embodiment, a method for playing a moving picture is provided. The dynamic picture playing method is executed on an execution device, and the execution device can be a computer device, a mobile device and other devices capable of playing dynamic pictures. Computer devices include desktop computers, handheld computers, and the like; the mobile device comprises an intelligent mobile terminal, such as a smart phone, a tablet computer and the like. The dynamic picture playing method comprises the following steps:
s110: and acquiring the dynamic picture to be played.
The dynamic picture is a picture with a dynamic effect obtained by encoding a group of static pictures according to a preset format. The group of still pictures includes a plurality of still pictures, each of which can be a frame, i.e., a still picture frame. The preset format is a format of a dynamic picture, and may be a GIF format. GIF is an abbreviation of Graphics exchange Format, and is originally an "image Interchange Format", which is an image file Format. The GIF format can store a plurality of still pictures, such as a plurality of color still pictures, and the simplest animation can be constructed by reading the plurality of still pictures stored in one GIF format moving picture file one by one and displaying the still pictures on a screen.
The dynamic picture to be played may be downloaded by a dynamic picture downloader (such as a GIF downloader) on the execution device, so as to acquire the dynamic picture.
S120: and decoding the dynamic picture to obtain a decoding result, wherein the decoding result comprises each static picture frame of the dynamic picture.
The decoding mode corresponds to the format of the dynamic picture, that is, what format is adopted to encode the static picture to obtain the dynamic picture, and then the decoding mode corresponding to the format of the dynamic picture is adopted to decode to obtain a decoding result. The decoding result necessarily includes each still picture frame. The still picture frame is a frame of data composed of a still picture.
Each still picture frame (e.g., GIF picture frame) may be obtained by decoding a moving picture with a moving picture decoder (e.g., GIF decoder) on the device.
S130: control data based on the moving picture playback device is received.
The moving picture playing apparatus is an apparatus for playing the moving picture, and may be an execution device, for example. The control data is an instruction for controlling the playing of the dynamic picture. The control data is received by the execution device. Specifically, the control data may be acquired by an equipment sensor of the execution equipment to obtain acquired data and control data obtained by processing the acquired data; acquiring the acquired data by a touch screen of the execution equipment and processing the acquired data to obtain control data; it is also possible that after an input operation by a user, the input is directly mapped to corresponding control data.
If the control data is control data obtained by acquiring the acquired data by the device sensor of the execution device and processing the acquired data, the input operation is an operation such as a motion condition of the execution device, for example, a rotation. The device sensor may be an acceleration sensor, a magnetic sensor, a gyroscope, etc., and the acquired sensor data may be processed by a data processor of the device sensor to obtain control data such as a rotational angular velocity and a rotational angle of the actuator.
And if the control data is the control data acquired by the touch screen of the execution equipment and obtained by processing the acquired data. The user can perform action operations on the touch screen of the execution device, for example, gesture action operations such as leftward sliding, rightward sliding, pre-pattern drawing and the like, and after the data of the action operations are collected by the touch screen, the action operation data are processed to obtain control data which can be recognized by the execution device.
If the control data is input by the user and then the input is directly mapped to a corresponding command, the input operation is to input data, a character string, or an action through the input device. The control data is the input data or the control data corresponding to the character string or the action, and the action can be a single click or a double click or a selection of a preset position.
S140: and determining the playing mode of the dynamic pictures according to the control data, wherein the playing mode comprises a playing sequence or/and a playing speed.
The execution device analyzes the control data, and can determine the playing mode of the dynamic picture represented by the control data. The playing sequence can be forward playing or reverse playing, wherein the forward playing is to play the dynamic pictures according to the sequence of the analyzed static picture frames, and the reverse playing is to play the dynamic pictures according to the reverse sequence of the analyzed static picture frames.
The playing speed can be represented by an acceleration factor, and the playing can be carried out according to the preset playing speed and then multiplied by the acceleration factor; the playing speed can also be represented by the interval time of each still picture frame, and the playing speed can be controlled according to the interval time of each still picture frame.
The playing mode of the dynamic pictures can be determined by the dynamic picture playing controller according to the control data, and the static picture frames to be played and the playing speed under the playing sequence are sent to the dynamic picture player. The play speed may be represented by a time interval at which a still picture frame to be played is played.
S150: and playing the static picture frames according to the playing sequence or/and the playing speed.
And the dynamic picture player of the execution equipment plays each static picture frame according to the playing sequence or/and the playing speed determined by the dynamic picture playing controller according to the control data, thereby controlling the playing of the dynamic picture. It is understood that the motion picture play controller is responsible for rendering and playing each still picture frame.
According to the dynamic picture playing method, the control data can be received in a mode of receiving the control data based on the dynamic picture playing device, and then the playing mode of the dynamic picture is determined according to the control data, wherein the playing mode comprises the playing sequence or/and the playing speed; and finally, playing the static picture frames according to the playing sequence or/and the playing speed. Therefore, the dynamic picture playing method improves the interactivity compared with the traditional dynamic picture playing mode.
It should be understood that, although the steps in the flowchart of fig. 1 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not limited to being performed in the exact order illustrated and, unless explicitly stated herein, may be performed in other orders. Moreover, at least a portion of the steps in fig. 1 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.
Referring to fig. 2, in one embodiment, the decoding result includes still picture frames arranged in a forward order and still picture frames arranged in a reverse order.
Each static picture frame arranged in the positive sequence can be obtained by decoding the dynamic picture in the positive sequence; and obtaining each static picture frame arranged in a reverse order by decoding the dynamic picture in a reverse order.
The step of playing each still picture frame according to the playing sequence or/and the playing speed comprises the following steps:
s252: and when the playing sequence is the positive sequence playing, playing the static picture frames arranged in the positive sequence according to the playing sequence.
S254: and when the playing sequence is the reverse order, playing the static picture frames arranged in the reverse order according to the playing sequence.
Thus, two playing modes of the forward playing sequence and the reverse playing sequence are realized.
It should be noted that, according to the file structure of the motion picture, the current still picture frame decoding may depend on the picture data of the previous still picture frame, and in the forward decoding process of the motion picture, the decoding is started from the 1 st frame, and when the next frame is decoded, the decoding result of the previous frame is used, so as to improve the decoding efficiency and achieve the expected animation effect of the motion picture. The difficulty in implementing the reverse decoding of the dynamic picture is high, when the nth static picture frame is randomly decoded, decoding needs to be started from the 1 st frame and is decoded to the current frame all the time, and when the decoding time consumption is equal to the total consumption of decoding the 1 st to nth frames, the decoding time is uncontrollable, and the dynamic picture cannot be guaranteed to achieve the expected animation effect.
Further, referring to fig. 3, the motion pictures include forward motion pictures and reverse motion pictures; decoding the positive sequence dynamic picture to obtain a decoding result comprising all static picture frames which are arranged in a positive sequence; the decoding result obtained by decoding the reverse order dynamic picture includes the static picture frames arranged in the reverse order.
The step of obtaining the dynamic picture to be played comprises the following steps:
s312: and acquiring a positive sequence dynamic picture.
S314: and decoding the positive sequence dynamic picture to obtain a first decoding result, wherein the first decoding result comprises all static picture frames which are arranged in a positive sequence.
S316: and combining the static picture frames into an inverted dynamic picture, wherein a second decoding result obtained after decoding the inverted dynamic picture comprises the static picture frames which are arranged in an inverted order.
The static picture frames are combined into the reverse order dynamic picture, and the static picture frames obtained by analyzing the forward order dynamic picture can be recoded by the dynamic picture coder, so that the reverse order dynamic picture is combined.
It can be understood that the decoding in this embodiment is forward decoding, so that the decoding efficiency can be improved, and the expected dynamic effect of the reverse dynamic picture can be achieved.
Therefore, before the dynamic picture is decoded to obtain a decoding result, the forward-sequence dynamic picture is decoded, and a reverse-sequence dynamic picture which is sequenced according to the reverse sequence arrangement sequence of the static picture frames in the forward-sequence dynamic picture is recombined. Before decoding the motion picture to obtain the decoding result, the motion picture is substantially changed from a forward motion picture to a combination of a forward motion picture and a reverse motion picture. Thus, each still picture frame of the forward-order moving picture arranged in the reverse order can be obtained by only performing forward decoding on the reverse-order moving picture without performing reverse decoding on the forward-order moving picture, and each still picture frame of the reverse-order moving picture arranged in the forward order can be obtained in accordance with the arrangement order of the still picture frames of the forward-order moving picture arranged in the reverse order. Therefore, the purposes of improving the decoding efficiency and achieving the expected dynamic picture playing effect are achieved.
In one embodiment, after the step of receiving the control data based on the moving picture playing apparatus, the method further includes: and updating the control data at preset time intervals. It can be understood that, after the control data is updated each time, the dynamic picture to be played needs to be obtained again, and the dynamic picture is decoded to obtain a decoding result, where the decoding result includes each static picture frame of the dynamic picture; determining the playing mode of the dynamic picture according to the control data, wherein the playing mode comprises a playing sequence or/and a playing speed; and playing the static picture frames according to the playing sequence or/and the playing speed. Therefore, the playing mode of the dynamic picture can be flexibly controlled.
In one embodiment, as shown in fig. 4, a hardware structure diagram of playing motion pictures is shown in accordance with an embodiment of the present invention. The moving picture is a moving picture in a GIF format. The positive sequence GIF dynamic picture can be obtained through a GIF downloader, and the positive sequence GIF dynamic picture is decoded through a GIF coder to obtain a first decoding result and is recoded to obtain a negative sequence GIF dynamic picture. In this embodiment, the sensor data is acquired by the device sensor, specifically, the sensor data is acquired once by being recalled every preset time (e.g., 100 ms), and the sensor data is processed by the data processor of the device sensor to obtain control data, such as the rotation angle and the pointing relationship. And the GIF playing controller calls a GIF decoder to decode the positive order GIF dynamic picture or the negative order GIF dynamic picture according to the directional relation in the control data to obtain each static picture frame arranged according to the positive order or the negative order, namely the GIF picture frame. And after the GIF picture frames are obtained, determining the playing speed according to the rotation angle of the control data, wherein the playing speed is represented by the playing time interval of each GIF picture frame to be played. And finally, playing the GIF picture frame to be played according to the time interval by using the GIF player, thereby realizing the playing control of the GIF dynamic picture.
In one embodiment, a system diagram of a video playback method presented in a class diagram format is shown in fig. 5. The system mainly comprises four modules of GIF downloading, GIF coding and decoding, frame data rendering and sensor control.
Among them, genericNewGifDecoder and NewGifDecoder are responsible for GIF decoding, newGifDrawable (gifcanvas) and AutoGifDrawable (autogifcanvas) are responsible for GIF rendering and playing, autoGifCallback is used for monitoring playing callback, gifloadlistener (gifdownload monitor) is responsible for GIF download callback monitoring, gifcontrolcallback (GIF play control callback) is responsible for GIF play control callback, gifPlayControllerCallback (GIF play controller) acquires sensor data and transfers the data to sensorgifdrawable (sensor autogirf canvas) to control GIF playing.
Referring to fig. 6, in one embodiment, the step of receiving control data based on the motion picture playing apparatus includes:
s432: and establishing a three-dimensional coordinate system based on the dynamic picture playing device.
In this embodiment, the moving picture playing apparatus may be an execution device. The enforcement device may be a mobile device. The three-dimensional coordinate system includes two mutually perpendicular x-axis, y-axis and z-axis. As shown in fig. 7, when the moving picture playing apparatus is vertically placed, the direction facing the screen horizontally to the right may be a positive x-axis direction, the direction facing vertically upward may be a positive y-axis direction, and the direction in which the vertical x-axis and y-axis screens are aligned may be a positive z-axis direction. As shown in fig. 8, when the moving picture playing device is placed horizontally and the screen is facing upward, the direction facing the horizontal right of the screen may be the positive direction of the x-axis, the vertical upward direction may be the positive direction of the z-axis, and the direction perpendicular to the x-axis and the z-axis and pointing from the lower end of the screen to the upper end of the screen may be the positive direction of the y-axis.
S436: and acquiring the directional relation between the positive direction of the first preset axis of the three-dimensional coordinate system and the horizontal plane, or/and acquiring the rotation angle or rotation angular velocity of the second preset axis of the three-dimensional coordinate system around the third preset axis of the three-dimensional coordinate system.
The first predetermined axis may be an x-axis, a y-axis, or a z-axis. The pointing relation may be that the positive direction of the first preset axis points above or below the horizontal plane. The second preset axis may also be an x axis, a y axis, or a z axis, and the second preset axis may be a coordinate axis different from the first preset axis, or may be the same as the first preset axis.
The control data comprise the rotation angle or rotation angular velocity or/and the directional relation. The step of determining the playing mode of the dynamic picture according to the control data comprises the following steps:
s442: and determining the playing sequence according to the directional relation, or/and determining the playing speed according to the rotation angle or the rotation angular speed.
When the pointing relationship is the first pointing relationship, it can be determined that the playing sequence is the forward playing sequence; when the pointing relationship is the second pointing relationship, it may be determined that the playing order is the reverse order playing. The first pointing relation may be that the positive direction of the first preset axis points to the upper side or the lower side of the horizontal plane; the second pointing relationship is a different pointing than the first pointing relationship. When the first pointing relationship is that the positive direction of the first preset axis points to the lower part of the horizontal plane, the second pointing relationship is that the positive direction of the first preset axis points to the upper part of the horizontal plane; when the first directional relation is that the positive direction of the first preset axis points to the upper part of the horizontal plane, the second directional relation is that the positive direction of the first preset axis points to the lower part of the horizontal plane.
When the playback speed is determined by the rotation angle, the playback speed is faster as the rotation angle is larger. When the playback speed is determined by the rotation angular velocity, the playback speed is faster as the rotation angle is larger. It is to be understood that, in the present embodiment, the playback speed is expressed by an acceleration factor, and playback is performed at a preset playback speed that is expressed by the interval time of each still picture frame recorded in the file format of the moving picture, multiplied by the acceleration factor. Specifically, the rotation angle or rotation angular velocity may be divided by a preset value, for example, 10, the obtained value is used as the acceleration factor, and the acceleration factor is multiplied by the preset playing speed to obtain the actual playing speed.
Referring to fig. 9, in an embodiment, before the step of obtaining the pointing relationship between the positive direction of the first preset axis of the three-dimensional coordinate system and the horizontal plane, or/and obtaining the rotation angular velocity of the second preset axis of the three-dimensional coordinate system around the third preset axis of the three-dimensional coordinate system, the method further includes the steps of:
s534: and acquiring an included angle between a fourth preset axis of the three-dimensional coordinate system and the horizontal plane.
The control data further includes an included angle; the step of determining the playing mode of the dynamic picture according to the control data comprises the following steps:
s542: and when the included angle meets a preset condition, determining a playing sequence according to the directional relation, or/and determining a playing speed according to the rotation angle or the rotation angular speed.
The fourth predetermined axis may be an x-axis, a y-axis or a z-axis in this embodiment. And determining the playing sequence according to the directional relation only when the included angle between the fourth preset axis of the three-dimensional coordinate axis and the horizontal plane meets the preset condition, or/and determining the playing speed according to the rotation angle or the rotation angular speed. The playing sequence is determined according to the pointing relationship, or/and the playing speed is determined according to the rotation angle or the rotation angular speed, so that the mode for controlling the playing of the dynamic pictures can be recorded as the device sensor control mode. In one embodiment, the fourth predetermined axis is the x-axis, and the predetermined condition is greater than 15 °. In this case, the playing sequence is determined according to the directional relationship only when the angle between the x-axis and the horizontal plane is greater than 15 °, or/and the playing speed is determined according to the rotation angle or the rotation angular speed.
Further, the decoding result further includes a preset playing mode. The preset playing mode may be a playing mode recorded in a file format of the moving picture, and may also include a playing sequence and/or a playing speed.
The step of determining the playing mode of the dynamic picture according to the control data further comprises the following steps:
s544: and when the included angle does not meet the preset condition, playing the dynamic picture according to a preset playing mode.
And when the included angle between the fourth preset axis and the horizontal plane does not meet the preset condition, the equipment sensor control mode is not entered, and the preset playing mode is entered. The preset playing mode is a mode for playing the dynamic picture according to the preset playing mode. It is understood that the predetermined playing mode also includes a playing sequence and/or a playing speed, and the predetermined playing sequence and/or the predetermined playing speed can be defined for the purpose of distinction. The preset playing sequence is carried in a file format of the dynamic pictures; the preset playing speed is the playing speed carried in the file format of the dynamic picture.
Therefore, the user can control the dynamic picture playing device, so that the included angle between the fourth preset axis of the dynamic picture playing device and the horizontal plane meets or does not meet the preset condition, and the dynamic picture is controlled to be played and controlled according to the subsequently input control data or the preset playing mode. The interactivity of the dynamic picture playing mode can be further improved, and meanwhile, the flexibility of the dynamic picture playing mode can be improved.
In one embodiment, a control process of a moving picture is described from the perspective of a user, and as shown in fig. 10, first, a device sensor acquires sensor data of a moving picture playing device, and processes the sensor data to obtain control data, that is, a rotation condition of the moving picture playing device. When the included angle between the fourth preset axis of the three-dimensional coordinate system and the horizontal plane is not more than 15 degrees, entering a preset playing mode; when the included angle between the fourth preset axis of the three-dimensional coordinate system and the horizontal plane is larger than 15 degrees, entering a sensor playing mode, and determining the pointing relation between the positive direction of the first preset axis of the three-dimensional coordinate system and the horizontal plane according to whether the rotation angle around the y axis is larger than 0, namely the first preset axis is the x axis. When the rotation angle of the y axis is greater than 0, the pointing relation is that the positive direction of the first preset axis points to the upper part of the horizontal plane, and the playing sequence is determined to be sequential playing; and when the rotation angle of the y axis is less than 0, the positive direction of the first preset axis points to the lower part of the horizontal plane, and the playing sequence is determined to be reverse playing. The second preset axis is an x-axis, the third preset axis is a y-axis, and the playing speed is determined according to the rotation angle of the x-axis of the three-dimensional coordinate system around the y-axis of the three-dimensional coordinate system, and is represented by an acceleration factor a, specifically, a = rotation angle/10 °. Therefore, when a dynamic picture appears on a browsing interface, such as a GIF dynamic picture, the dynamic picture playing device is rotated around the y axis, a sensor control mode can be entered, and then the playing sequence can be controlled by utilizing the included angle between the x axis of the dynamic picture playing device and the horizontal plane, when the x axis points to the lower part of the horizontal plane, the GIF dynamic picture is played in a positive sequence, otherwise, the GIF dynamic picture is played in a reverse sequence, and when a user wants to recover the normal playing mode, the included angle between the x axis of the dynamic picture playing device and the horizontal plane is smaller than 15 degrees.
In one embodiment, a timing diagram of the moving picture playing method is shown in fig. 11. Firstly, a user rotates the dynamic picture playing device, the dynamic picture playing device transmits the rotation to the equipment sensor, namely, the equipment sensor acquires sensor data and processes the sensor data to obtain control data. The pointing relation between the positive direction of the first preset axis and the horizontal plane is represented by whether the rotating angle is larger than 0 degrees, and the included angle between the preset axis and the horizontal plane can be represented by the rotating angle of the x axis. There are three cases, such as 1.1.1, 2.1.1 and 3.1.1 in the timing diagram. When the rotation angle is larger than 15 degrees, the sensor control mode is adopted, and the playing sequence is positive sequence playing; when the rotating angle is less than-15 degrees, the sensor control mode is also adopted, and the playing sequence is in reverse order; when the rotation angle is between-15 ° and 15 °, the playback mode is the preset playback mode, and the playback sequence is the preset playback sequence. And after the decoder decodes the dynamic pictures according to the control data, returning the static picture frames obtained by decoding to the player, so that the dynamic picture playing device plays the dynamic pictures according to the playing sequence.
