Based on the above problems, embodiments of the present application provide a video playing processing method, an apparatus, a storage medium, and a terminal, which can effectively improve efficiency of clearing junk data in a memory of the terminal. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a video playing processing method according to an embodiment of the present disclosure. The video play processing method may be applied to mobile terminals such as terminals, tablet computers, notebook computers, palmtop computers, Portable Media Players (PMPs), and fixed terminals such as desktop computers. The specific flow of the video playing processing method can be as follows:
101. and acquiring a video frame image corresponding to the video playing interface.
Specifically, before the video frame image corresponding to the video playing interface is obtained, the state of the currently played video file at the terminal may be determined. The state of the video file at the terminal may be various, such as cached, uncached, cached, and the like.
After determining the status of the video file, a video frame image of the video file may be acquired. Specifically, the mode of acquiring the video frame image may be determined according to the state of the video file, for example, when the state of the video file is cached, the video file may be represented as a local file, and when the video frame image is acquired, the video frame image data may be directly extracted from the video file data stored in the terminal; for another example, when the video file is not cached, it may indicate that the video file is an online playing video, and when the video frame image is obtained, the video frame image may be obtained from the server side, and so on.
For example, the currently played video file may be in an uncached state, that is, the currently played video file may be played online, and in the playing process of the video file, the video frame image may be acquired, and the video frame image may be acquired from the server.
102. A first luminance component and a first chrominance component are extracted based on a video frame image.
Specifically, a first luminance component and a first chrominance component are extracted based on the video frame image, image information of the video frame image may be acquired, and the first luminance component and the first chrominance component are extracted according to the acquired image information. The image information may include resolution, color, brightness, and the like, among others.
In some embodiments, the step of "extracting a first luminance component and a first chrominance component based on the video frame image" may include the following processes:
acquiring color information of the video frame image in a specified color space;
and performing separation processing on the color information to obtain the first brightness component and the first chrominance component.
Specifically, the color information of the video frame image in a designated color space is obtained, where the color space may include multiple color spaces, such as RGB (Red, Green, Blue) color space, CMY (Cyan, Magenta, Yellow) color space, YUV (luminance, chrominance) color space, and the like, and different color spaces are composed of different parameters, and the color is described in different manners.
The designated color space in the embodiment of the present application may be a YUV color space, because the present solution designs the video playing field, and the YUV color space is a color coding method adopted by the european television system, and is a color space adopted by a PAL (phase alternation Line) and SECAM (sequential Couleur a mean, which sequentially transmits and stores colors) analog color television systems.
YUV is a color space that describes color by luminance-chrominance difference. The luminance signal is often referred to as Y and the chrominance signal is composed of two mutually independent signals. Depending on the color system and format, the two chrominance signals are often referred to as UV. These are all generated by different coding formats, but in practice their concepts are substantially the same.
In a modern color television system, a three-tube color camera or a color CCD (Charge coupled device) camera is usually used for image capture, then the obtained color image signals are subjected to color separation and respective amplification and correction to obtain RGB, a luminance signal Y and two color difference signals B-Y (i.e., U) and R-Y (i.e., V) are obtained through a matrix conversion circuit, and finally, a transmitting end encodes the luminance signal and the color difference signals respectively and transmits the signals through the same channel. This color representation is called YUV color space representation. The importance of using the YUV color space is that its luminance signal Y and chrominance signal U, V are separate.
Specifically, color information of a video frame picture in a YUV color space is obtained, where the color information may include a luminance component (Y) and a chrominance component (UV), where before processing the color information, video bare data of the video frame picture may be obtained, the color data is extracted from the video bare data, the obtained color data is the color information, and then the color data may be separated, so that the luminance component and the chrominance component may be obtained. For example, the first luminance component acquired may be 10, the first chrominance component may be 10, and so on.
103. The first luminance component and the first chrominance component are adjusted according to a user operation.
Specifically, the first luminance component and the first chrominance component are adjusted according to user operation, and after the first luminance component and the first chrominance component are separated from the video frame image data, the first luminance component and the first chrominance component can be displayed on a current display screen interface, so that the user can adjust the first luminance component and the first chrominance component according to viewing requirements.
In some embodiments, the step of "adjusting the first luminance component and the first chrominance component according to a user operation" may include the following processes:
acquiring touch operation of a user on a video playing interface;
displaying a setting control on a current video playing interface according to the touch operation;
and triggering an adjusting instruction through the setting control, adjusting the first brightness component and the first chrominance component according to the adjusting instruction, and displaying the adjusted brightness component and chrominance component on a video playing interface.
Specifically, the touch operation of the user on the play interface is obtained, and the touch operation of the user on the play interface may include multiple types, for example, the user may perform an operation by touching the display screen in a click manner, a sliding manner, or the like. After the touch operation of the user is detected, the setting control can be displayed according to the touch operation of the user, and the setting control can be a setting button or the like, wherein before the setting button is displayed, the touch operation of the user can be compared with a preset touch operation, and whether the touch operation of the user is the preset touch operation is judged.
For example, the user touch operation may be a single-click display screen, the preset touch operation may be a double-click display screen, and if it is determined that the user touch operation does not conform to the preset touch operation, the setting button is not displayed; for another example, the user touch operation may be a single-click on the display screen, the preset touch operation may be a single-click on the display screen, and it may be determined that the user touch operation matches the preset touch operation, and then the setting button may be displayed. Touch operation is preset through setting, user misoperation can be avoided, and therefore the user experience of watching videos is influenced by displaying a setting button on a video playing interface.
After the setting button is displayed according to the touch operation of the user, the user can click the setting button to enter a setting interface, then receives an adjusting instruction, can adjust the first brightness component and the first chrominance component according to the adjusting instruction, and displays the adjusted brightness component and the adjusted chrominance component on a video playing interface. The adjustment instruction may be triggered by a user, and the luminance component and the chrominance component may be adjusted according to a user touch operation through a user touch operation and the like.
In some embodiments, the step of triggering an adjustment instruction through the setting control, and adjusting the first luminance component and the first chrominance component according to the adjustment instruction may include the following steps:
when receiving the moving operation of the first section of sliding block and the second adjusting sliding block, triggering an adjusting instruction;
acquiring a first moving distance of the first adjusting slide block;
acquiring a second moving distance of the second adjusting slide block;
and determining the adjusted brightness component according to the first moving distance, and determining the adjusted brightness component according to the second moving distance.
Specifically, after entering the setting interface according to the user touch operation, the setting interface may include a luminance component adjusting module, a chrominance component adjusting module, and the like, the luminance component adjusting module may include a first slider, and the user may adjust the first luminance component by sliding the first slider; the chrominance adjustment module may include a second slider by which a user may adjust the first chrominance component.
The first moving distance of the first slider is obtained, the adjusted luminance component can be determined by the first moving distance, and the corresponding relationship between the moving distance and the adjusted luminance component can be preset, for example, the moving distance can be 1 mm, the adjusted luminance component can be 10, and the like.
For example, the current first luminance component may be 10, and if the first slider is moved by 2 mm according to the user touch operation, the luminance component is adjusted to be 20, and the adjusted first luminance component is 30.
The second moving distance of the second slider is obtained, the adjusted chromaticity component can be determined by the second moving distance, and the corresponding relationship between the moving distance and the adjusted chromaticity component can be preset, for example, the moving distance can be 1 mm, the adjusted chromaticity component can be 20, and the like.
For example, the current first chromaticity component may be 10, and if the second slider is moved by 2 mm according to the user touch operation, the luminance component is adjusted to 40, and the adjusted first chromaticity component is 50.
In some embodiments, after the step "displaying a setting control on the current video playing interface according to the touch operation", the following steps may be further included:
if the user operation is not detected within a preset time period, acquiring a historical adjustment information set, wherein the historical adjustment information set comprises adjustment information of a plurality of historical playing video files;
and adjusting the first brightness component and the first chrominance component according to the historical adjustment information set.
Specifically, after the first luminance component and the first chrominance component are determined, in a preset time period, if a user operation is detected, a historical adjustment information set may be obtained, where the historical adjustment information set may include a plurality of videos watched by the user in a historical time, luminance components and chrominance components of the plurality of videos, and all information for adjusting and setting the luminance components and the chrominance components, so that the luminance components and the chrominance components may be adjusted according to the historical adjustment information set when the video is watched next time, and adjustment efficiency may be improved.
In some embodiments, the step of "adjusting the first luminance component and the first chrominance component according to the historical set of adjustment information" may comprise the steps of:
obtaining all historical brightness components and historical chrominance components according to the historical adjustment information set, and adjusting the historical brightness components and the historical chrominance components to obtain target brightness components and target chrominance components;
determining a brightness component with the minimum difference value with the first brightness component from all the historical brightness components as a second brightness component;
determining a chroma component with the minimum difference value with the first chroma component from all historical chroma components as a second chroma component;
adjusting the first brightness component based on a target brightness component corresponding to the second brightness component;
and adjusting the first chrominance component based on the target chrominance component corresponding to the second chrominance component.
Specifically, the historical adjustment information set may include adjustment information of a plurality of sample files, where a sample file may be a video file historically viewed by a user, and the adjustment information of a sample file may include an initial luminance component (historical luminance component) and an initial chrominance component (historical chrominance component) and an adjusted luminance component (target luminance component) and a chrominance component (target chrominance component) when the user views the sample file.
After the historical luminance components and the historical chrominance components of all the sample files are obtained, the historical luminance components can be compared with the first luminance component, and the historical luminance component with the smallest difference value with the first luminance component is determined to be used as a second luminance component; and comparing the historical chrominance component with the first chrominance component, and determining the historical chrominance component with the minimum difference value with the first chrominance component as a second chrominance component.
Specifically, a target luminance component corresponding to the second luminance component and a target chrominance component corresponding to the second chrominance component are obtained from the adjustment information set, and then the first luminance component may be adjusted based on the target luminance component corresponding to the second luminance component; and adjusting the first chrominance component based on the target chrominance component corresponding to the second chrominance component.
For example, the historical adjustment information set may include a first sample file, a second sample file, and the like, and the adjustment information corresponding to the first sample file may include that the first sample luminance component is 0, the first sample chrominance component is 0, the first target luminance component is 50, and the first target chrominance component is 50; the adjustment information corresponding to the second sample file may include that the second sample luma component is 100, the second sample chroma component is 50, the second target luma component is 30, the second target chroma component is 0, and the like, the first luma component may be 10, the first chroma component may be 50, it may be determined that the difference between the first sample luma component and the first luma component is minimum, and the difference between the second sample chroma component and the first chroma component is minimum, the first luma component may be adjusted to 50, and the first chroma component may be adjusted to 0.
