Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.
A transcoding control method, apparatus, electronic device, and storage medium of video data according to an embodiment of the present disclosure are described below with reference to the drawings.
Fig. 1 is a flowchart illustrating a transcoding control method for video data according to an embodiment of the present disclosure.
As shown in fig. 1, the transcoding control method of video data includes:
s101, acquiring original video data to be processed.
The transcoding control method for video data according to the embodiment of the present disclosure is configured in a transcoding control apparatus for video data, and the transcoding control apparatus for video data may be set in an application having a video sharing function, and the application may be set in an electronic device or a server, which is not limited in this embodiment.
The electronic device may include, but is not limited to, a mobile phone, a tablet computer, a wearable device, and the like, and the embodiment is not limited thereto.
The implementation of the present disclosure is described by taking a user publishing a video using a short video-like application in an electronic device as an example.
It should be noted that, in the process that the user issues the video through the short video application program, the video data to be processed may be video data directly recorded by the user through the short video application program, may also be video data locally imported by the user, and may also be video data generated by the short video application program according to multiple pictures through locally importing multiple pictures by the user, which is not limited in this embodiment.
S102, determining a code rate and a key frame interval corresponding to the original video data according to the video parameter information of the original video data.
The video parameter information may include, but is not limited to, a video frame rate, a video resolution, and the like, which is not limited by this embodiment.
As a possible implementation manner, the video frame rate and the video resolution in the video parameter information of the original video data are obtained, and the code rate and the key frame interval corresponding to the original video data are determined according to the video frame rate and the video resolution.
It should be noted that, generally, the higher the resolution of the video is, the higher the determined bitrate corresponding to the original video data is; the higher the video frame rate, the higher the determined bitrate corresponding to the original video data.
It should be noted that the key frame interval refers to an interval between I frames in the original video data, that is, the key frame interval is an I frame interval.
And S103, transcoding the original video data again to output target video data corresponding to the code rate and the key frame interval.
Specifically, after the code rate and the key frame interval corresponding to the original video data are determined, the target video data corresponding to the code rate and the key frame interval can be output when the encoder is controlled to re-encode the original video data according to the code rate and the key frame interval.
According to the transcoding control method of the video data, the code rate and the key frame interval corresponding to the original video data are determined according to the video parameter information of the original video data to be processed, and the original video data are transcoded again according to the code rate and the key frame interval, so that target video data corresponding to the code rate and the key frame interval are obtained. Therefore, the code rate is controlled by combining the video parameter information of the video data to be processed, the code rate control in the transcoding process is realized, and the target video with the code rate and the key frame interval according with the video parameters is transcoded.
The disclosed embodiment provides another transcoding control method for video data, which is a further extension and optimization of the method shown in fig. 1.
Fig. 2 is a flowchart illustrating another transcoding control method for video data according to an embodiment of the present disclosure.
As shown in fig. 2, the transcoding control method for video data includes:
s201, acquiring original video data to be processed.
S202, whether the original video data needs to be transcoded again is determined.
It should be noted that, in different application scenarios, it is determined that the original video data needs to be transcoded in different ways, for example, the following are described:
as an example, it is identified that the video frame rate of the original video data exceeds a preset frame rate threshold, and it is determined that the original video data needs to be transcoded again.
Specifically, whether the video frame rate of the original video data exceeds a preset frame rate threshold or not can be judged according to the video parameter information, and if the video frame rate exceeds the preset frame rate threshold, the original video data is determined to need transcoding again.
As another example, identifying the original video data as imported by the user, it is determined that the original video data needs to be re-transcoded.
Specifically, whether the original video data is imported by a user is judged, and if the original video data is imported by the user, the fact that the original video data needs to be transcoded again is determined
As a possible implementation manner, whether the original video data is imported by the user is determined, and whether the original video data is imported by the user may be determined, where if the original video data is marked with an import identifier, it is determined that the original video data needs to be transcoded again.
It should be noted that, the original video data is marked with an import identifier, which indicates that the original video data is the video data imported from the local by the user.
As another example, identifying that the original video data uses special effects, it is determined that the original video data needs to be re-transcoded.
Specifically, it may be determined whether the original video data uses a special effect, where if the original video data uses a special effect, it is determined that the original video data needs to be transcoded again.
As a possible implementation manner, whether the original video data uses a special effect is judged, whether the original video data to be processed uses the special effect can be judged by judging whether the original video data is marked with a special effect identifier, if the original video data is marked with the special effect identifier, the original video data to be processed uses the special effect is judged, and if the original video data is marked with any special effect identifier, the original video data to be processed does not use the special effect.
As another example, identifying that the original video data uses a preset special effect, it is determined that the original video data needs to be re-transcoded.
The preset special effect is a special effect for adding a special effect to video image data in original video data. The preset effects may include, but are not limited to, color filters, effect filters, any effect such as stickers, watermarks, text, paintbrushes, etc., as the implementation defines.
As another example, it is determined that the original video data needs to be re-transcoded if it is identified that the size of the original video data exceeds a preset threshold.
Specifically, when it is required to determine whether the original video data is transcoded, it may be determined whether the size of the original video data to be processed exceeds a preset threshold, and if the size of the original video data exceeds the preset threshold, it is determined that the original video data needs to be transcoded again.
It can be understood that the size of the original video data may be calculated according to the video code rate and the video duration, or may be obtained by reading the video parameter information of the video data, which is not limited in this embodiment.
S203, performing encapsulation processing on the original video data, or copying a video name of the original video data.
In order to avoid resource waste caused by performing encapsulation processing again on the original video data meeting the requirements, as an exemplary implementation manner, before performing encapsulation processing on the original video data, it may be further determined whether an audio track and/or a video track of the original video data is added with a special effect, and if the audio track and/or the video track is added with the special effect, the audio track and the video track of the original video data are repackaged according to the special effect used on the audio track and/or the video track of the original video data.
When the audio track and/or the video track of the original video data are not added with special effects, transcoding processing and packaging processing of the original video data are not needed, and at the moment, the video name of the original video data can be directly copied.
And S204, determining code rate and key frames corresponding to the original video data according to the video parameter information of the original video data.
S205, re-transcoding the original video data to output target video data corresponding to the bitrate and the key frame interval.
As an exemplary embodiment, in order to share the target video data so that the user can view the target video data on the video platform, the target video data may also be published to the video platform after S205 is performed.
In practical application, in the process of publishing video data to a video platform, a user may use a special effect for a video track and/or an audio track of the video data through a short video-class application program, as an exemplary embodiment, in order to enable the user to view a video to which a corresponding special effect is added on the video platform, before publishing target video data to the video platform, the target video data may be repackaged, and the target video data after being capsulated is published to the video platform.
Specifically, the video track and the audio track of the video data are repackaged according to the special effect used on the video track and/or the audio track of the video data, and the target video data after being packaged is released to the video platform.
The transcoding control method of the video data of the embodiment of the disclosure acquires original video data to be processed, judges whether the original video data needs transcoding, determines a code rate and a key frame interval corresponding to the original video data according to video parameter information of the original video data to be processed when the original video data needs transcoding, and re-transcodes the original video data according to the code rate and the key frame interval to obtain target video data corresponding to the code rate and the key frame interval. Therefore, for the video data needing transcoding, the control of the code rate and the key frame interval in the transcoding process is realized by combining the video parameter information of the video data, and the target video with the code rate and the key frame interval conforming to the video parameters is transcoded.
The disclosed embodiment provides another transcoding control method for video data, which is a further extension and optimization of the method shown in fig. 1.
Fig. 3 is a flowchart illustrating another transcoding control method for video data according to an embodiment of the present disclosure.
As shown in fig. 3, the transcoding control method of video data includes:
s301, acquiring original video data to be processed.
S302, determining whether the original video data is imported by the user, if yes, executing S307 and S310, and if no, executing S303.
S303, determine whether the original video data uses special effects, if yes, execute S304.
It should be noted that, if the original video data does not use a special effect, it is determined that the original video data does not need to be transcoded again.
S304, judging whether the original video data uses a preset special effect, if so, executing S308-S310, otherwise, executing S305.
The preset special effects may include, but are not limited to, color filters, special effect filters, any stickers, watermarks, texts, paintbrushes, and other special effects, which is limited by this implementation.
The preset special effect is a special effect for adding a special effect to video image data in original video data.
S305, determining whether a special effect is added to the audio track and/or the video track of the original video data, if yes, executing S306.
As a possible implementation manner, whether to add a special effect to the audio track and/or the video track of the original video data may be determined by determining whether the audio track and the video track of the original video data are marked with a special effect identifier.
If the audio track and the video track of the original video data are marked with special effect marks, the audio track and the video track of the original video data are judged to be added with special effects.
If the audio track of the original video data is marked with the special effect identification, but the video track is not marked with the special effect identification, the audio track of the original video data is judged to be added with the special effect.
If the video track of the original video data is marked with the special effect identification, but the audio track is not marked with the special effect identification, the video track of the original video data is judged to be added with the special effect.
S306, repackaging the audio track and the video track of the original video data according to the special effect added to the audio track and/or the video track of the original video data.
As an exemplary embodiment, after repackaging the audio track and the video track of the original video data, the video data may be distributed to the video platform after being packaged so that the video data may be shared with other users.
S307, according to the video parameter information of the original video data, determining the code rate and the key frame interval corresponding to the original video data.
S308, acquiring the motion information of the electronic equipment when recording the original video data.
The motion information of the electronic device during recording of the original video data can be obtained through motion information measured by a gyroscope in the electronic device.
S309, determining the video parameter information according to the original video data according to the video parameter information and the motion information of the original video data.
It should be noted that, in the process of recording the original video data, the motion information of the electronic device has a certain influence on the determined code rate and the key frame interval.
In the process of recording original video data, the more drastic the motion amplitude of the electronic device is, and during encoding, the higher the code rate of the video data output by the encoder is required to be, the smaller the key frame interval is.
S310, transcoding the original video data again to output target video data corresponding to the code rate and the key frame interval.
The transcoding control method of the video data of the disclosed embodiment obtains original video data to be processed, and judges whether the original video data is marked with an import mark, if so, determines the code rate and key frames corresponding to the original video data according to the video parameter information of the original video data, and re-transcodes the original video data to output target video data corresponding to the code rate and key frame intervals, and determines whether the original video data needs transcoding by combining the special effect use condition of the original video data when the original video data is not marked with the import mark, and determines the code rate and key frame intervals corresponding to the original video data by combining the video parameter information and motion information of the original video data when transcoding processing is needed, and controls the transcoding of the original video data among frames according to the determined code rate and key, to output the target video data spaced from the bitrate and key frame. Therefore, whether the original video data need transcoding is determined by combining the condition of the original video data, and when transcoding is needed, the control of the code rate and the key frame interval in the transcoding process is realized by combining the video parameter information of the video data and the motion information of the electronic equipment, and the target data of which the code rate and the key frame interval accord with the video parameters and the motion information is transcoded.
It should be noted that, after adding special effects to the original video data through the short video application program, some of the added special effects (for example, a time special effect flashes, slow motions, etc.) may also affect the frame rate of the original video, and further affect the determined bitrate.
