Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
With the development of multimedia technology, the image quality of the original video obtained by the acquisition of video acquisition sensor is constantly mentioned
Height, correspondingly, the data volume that the original video of high image quality includes are equally larger.It is thus typically necessary to above-mentioned original video into
Row coding, to remove the redundancy of original video, reduces the data volume of original video, convenient for the transmission and storage of video.
When the relevant technologies encode original video using encoder, the work such as the code rate of encoder ginseng is set in advance
Number, and start the encoder, then the encoder encodes original video according to the code rate of setting.Wherein, for highest version
System (such as version be higher than Android 19 system), encoder can compiled according to the complexity of original video frame
Dynamic adjustment is carried out to code rate during code.However for the system of lowest version, (such as version is lower than Android 19
System), it when being adjusted code rate, needs again to be configured the code rate of the encoder, and restart the encoder, so as to compile
Code device encodes original video according to newly-installed code rate, and operating process is cumbersome, inefficient.
For this purpose, the embodiment of the invention provides a kind of modes that need not restart encoder come the method that dynamically adjusts code rate,
The method of dynamic adjustment code rate can be applied in implementation environment as shown in Figure 1.In Fig. 1, including client 11, encoder
12, at least one input block 13 and at least one output buffer 14.
Client 11 obtains the input block 13 of at least one blank first, and slow to the input of at least one blank
It rushes and inserts data to be encoded in area 13；Encoder 12 obtains data to be encoded from the input block 13, waits compiling to this
The data of code are encoded；After completing coding, encoder 12 buffers the output that the data after coding insert at least one blank
Area 14, data of the client 11 after it can obtain coding in the output buffer 14.
After client 11 obtains the data after coding, it can play out or transmit etc. operating to it.In addition, also releasable
Data after the coding being received in the data to be encoded and output buffer 14 being received in input block 13, it is complete
At after release output buffer 13 and output buffer 14 become the blank buffer area that can be received in data, client 11 again
With encoder 12 it can be carried out again using.
Based on above-mentioned implementation environment shown in FIG. 1, referring to fig. 2, the embodiment of the invention provides a kind of dynamics to adjust code rate
Method, this method can be applied in the client 11 of implementation environment shown in Fig. 1.As shown in Fig. 2, this method comprises:
Step 201, video data to be encoded is obtained, which carries initial code timestamp；
Wherein, which can be to pass through video camera or other acquisition collected original videos of equipment
Data, the original video data are un-encoded video data；The video data to be encoded may be to pass through decoder
Decoded video file is completed, before being decoded by decoder, which is the original video data encoded,
After decoder completes decoding, then original video data can be regained, and press different coding modes, by the original video data
As video data to be encoded, encoded again.
The video data carries initial code timestamp, which is the time index in cataloged procedure,
Encoder can encode video data to be encoded according to the initial code timestamp: when encoder is according to the initial code
Between stamp confirm the time span of its corresponding video data, and then complete to the coding of video data.For example, when encoder is at certain
One moment got the initial code timestamp of 1s (second), then can confirm the video data for having got that time span is 1s, so
Afterwards, encoder can encode the video data in 1s.
In addition to initial code timestamp, which can also carry the data informations such as coloration, brightness and frame per second.Its
In, coloration, brightness are the organoleptic indicator of human body, and frame per second is the frame number for the still picture that 1 second video includes, and are being broadcast
When putting, quickly continuous broadcasting is carried out to above-mentioned still picture, the illusion of movement can be formed in human eye, also, in 1 second
The frame number of the still picture of broadcasting is more, and the motion artifact of formation is more smooth, it may be said that frame per second is a video smoothness degree
Evaluation index.
In collection process, frame per second can be configured by camera or other acquisition equipment.By taking camera as an example, if
The frame per second for setting camera is 20fps (frames per second, frame are per second), then the camera each second, it is static to acquire 20 frames
Picture data.Wherein, every frame still image data can correspond to an initial code timestamp, and initial code timestamp is usual
With ms (millisecond) for unit.For example, the 20 frame still image datas that camera acquires in the 1st second, then the 1st frame is collected quiet
Only picture data, initial code timestamp are 50ms, the collected still image data of the 2nd frame, initial code timestamp
For 100ms, and so on, the collected still image data of the 20th frame, initial code timestamp is 1000ms.
Step 202, it is adjusted according to initial code timestamp of the scramble time stamp interval of pre-adjustment to video data,
Video data after being adjusted, the video data adjusted carry scramble time stamp adjusted；
Wherein, it is adjusted by the initial code timestamp to video data, changes the initial volume of each of video data
Interval between code timestamp, above-mentioned adjustment process can be carried out repeatedly, so that being divided into pre-adjustment between scramble time stamp adjusted
Scramble time stamp interval.
Encoder is the time span of the video data got according to scramble time stamp confirmation, therefore, for a certain
The video data of time span adjusts the video data initial code timestamp by the scramble time stamp interval of pre-adjustment
It is whole, thus it is possible to vary judgement of the encoder to the time span of the video data.For example, the video counts for being 1s for time span
According to the initial code timestamp of one-frame video data is 500ms, and the initial code timestamp of one-frame video data is 1s, then will
The initial code timestamp of the 500ms is adjusted to 1s, and the initial code timestamp of the 1s is adjusted to 2s, i.e. initial code time
It is divided into 500ms between stamp, 1s is divided between scramble time stamp adjusted, then after encoder obtains the scramble time stamp adjusted,
The time span of the video data can be determined as 2s, and in fact, the time span of the video data is still 1s.
Step 203, by video data transmission adjusted to encoder, when which is used for according to coding adjusted
Between stab the video data adjusted encoded.
Wherein, after completing to the creation of an encoder, need to be arranged the running parameters such as the code rate of the encoder, and start
The encoder, then the encoder encodes original video according to the code rate of setting.It should be noted that above-mentioned code rate is to adopt
After being encoded with the encoder to video data to be encoded, the video data encoded of encoder each second output
Size.For example, the code rate of setting encoder is 100kbps (kilo bits per second, kilobits per second), the then coding
After device carries out the coding of 1s to video data to be encoded, the video data size encoded of output is 100kb (kilo
Bits, kilobit).
Next, being still 500ms with initial code timestamp and 1s, scramble time stamp adjusted are 1s and two frames of 2s
For video data, the method for dynamic provided in an embodiment of the present invention adjustment code rate is illustrated:
Assuming that the code rate of encoder is arranged to 100kbps, i.e., the data that encoder 1s interior coding comes out are 100kb；Just
Beginning scramble time stamp is 500ms and 1s, i.e., one second two frame video datas of coding, size of data 100kb, every frame video data
It can be averagely assigned to 50kb, actual bit rate is 50kb/ frame x2 frame/s=100kbps；Scramble time stamp adjusted is 1s and 2s,
I.e. one second coding one-frame video data, size of data 100kb, the data that every frame encodes out can averagely be assigned to 100kb,
And having two frame video datas practical each second, i.e., actual bit rate is 100kb/ frame x2 frame/s=200kbps.
Video data is encoded according to scramble time stamp adjusted, so that the actual code of the video data after coding
Rate changes, thus under the premise of not restarting encoder, realize the dynamic adjustment to the video data rate after coding.
In a kind of optional embodiment, referring to Fig. 3, this method further include:
Step 204, network communication quality is detected, determines the scramble time stamp interval of pre-adjustment according to testing result.
In a kind of optional embodiment, referring to fig. 4, this method further include:
Step 205, the scramble time stamp interval for obtaining setting, using the scramble time stamp interval of setting as the volume of pre-adjustment
Code interval of timestamps.
Pass through camera or the original video data of other acquisition equipment acquisitions, usually carrying coloration, brightness and frame per second etc.
Data information, and the basic principle that encoder is encoded is, the redundant data information that removal original video data carries, into
And the data volume of the original video is reduced, in order to the storage and transmission of video.Wherein, redundant data information includes easily by human eye
The luminance information etc. that the chrominance information ignored, human eye can not be distinguished.
It can be seen that the redundant data information content removed in an encoding process is fewer, the video data volume after being encoded is just
Bigger, then the code rate of the video data after being encoded is higher, that is, the image quality of video data and original video data after being encoded
Difference is smaller；Similarly, the redundant data information content removed in an encoding process is more, be encoded after the video data volume with regard to smaller,
The code rate of video data after being then encoded is lower, that is, the image quality difference of video data and original video data after being encoded is got over
Greatly.
If only from image quality angle analysis, the code rate of video data is the bigger the better；But correspondingly, the video data pair of high code rate
The demand of network transfer speeds is also higher, once network transfer speeds are lower than the code rate of video data, in storage and transmission process
In just will appear Caton or even phenomena such as stagnate, cause the reduction of efficiency of transmission.
Therefore, the embodiment of the present invention first carries out network communication quality before determining the scramble time stamp interval of pre-adjustment
Detection determines the scramble time stamp interval of pre-adjustment according to testing result, to prevent from blocking in storage and transmission process
Phenomena such as pausing, stagnating；Alternatively, the embodiment of the present invention can also directly acquire between the scramble time stamp of the customized pre-adjustment of user
Every to be adjusted according to the interval of timestamps of pre-adjustment to initial code timestamp, so that the code rate of video data meets
The demand of user.
Optionally, the present embodiment can code displaying interval of timestamps set interface, the set interface provide input frame, user
The interval of timestamps of customized pre-adjustment can be keyed in by the input frame of the set interface；Alternatively, set interface offer can
The interval of timestamps of the pre-adjustment of choosing, user also may select from the interval of timestamps of pre-adjustment.
In a kind of optional embodiment, the first scramble time stamp interval is divided between the scramble time stamp of pre-adjustment, it should
First scramble time stamp interval is greater than the corresponding initial code interval of timestamps of initial code timestamp；
Then it is adjusted according to initial code timestamp of the scramble time stamp interval of pre-adjustment to video data, comprising:
It is adjusted according to initial code timestamp of the first scramble time stamp interval to the video data.
By taking the code rate of encoder is arranged to 100kbps as an example, which is illustrated:
Table 1
| 50 | 100 | 150 | 200 | 250 | 300 | 350 | 400 | 450 | 500 |
| 550 | 600 | 650 | 700 | 750 | 800 | 850 | 900 | 950 | 1000 |
Table 2
| 100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900 | 1000 |
| 1100 | 1200 | 1300 | 1400 | 1500 | 1600 | 1700 | 1800 | 1900 | 2000 |
The code rate of encoder is arranged to 100kbps, i.e., the data that encoder 1s interior coding comes out are 100kb；It is initial to compile
Code timestamp is referring to table 1, i.e., one second 20 frame video datas of coding, size of data 100kb, and every frame video data is averaged energy
It is assigned to 5kb, actual bit rate is 5kb/ frame x20 frame/s=100kbps；Scramble time stamp adjusted was referring to table 2, i.e., one second
Ten frame video datas, size of data 100kb are encoded, the data that every frame encodes out can averagely be assigned to 10kb, and practical every
Second there are 20 frame video datas, i.e. actual bit rate is 10kb/ frame x20 frame/s=200kbps.
Therefore, according to the first scramble time stamp interval, i.e. interval between increase initial code timestamp, to video data
Initial code timestamp be adjusted, can make output video data code rate increase.
Optionally, the scramble time stamp interval of pre-adjustment may be the second scramble time stamp interval, this second coding when
Between stamp interval be less than the corresponding initial code interval of timestamps of initial code timestamp；
It is then adjusted, wraps according to initial code timestamp of the scramble time stamp interval of pre-adjustment to the video data
