FIG. 1 is an offline transcoding method provided by an embodiment of the present application, which is applicable to an offline transcoding system, and the method includes the following steps S10-S13.

In step S10, the transcoding task data sent by the transcoding control device is received, and the transcoding task data includes a storage path and transcoding configuration information of the video file to be transcoded.

The transcoding control device may be a computer used by a video service provider editor, a server console, etc., for calling a service interface of the offline transcoding system, and delivering the transcoding task data.

The storage path of the video file to be transcoded may be a storage path of the video file to be transcoded in the cloud storage system, and the cloud storage system is a plurality of node servers for saving the source video file, and is distributed in each area.

The transcoding configuration information is an attribute parameter of the transcoding task configured by the editing personnel through the transcoding control device, including: black edge removal, occlusion identification, audio track and channel selection, picture rotation, adding subtitles, and custom aspect ratio. , volume adjustment, bit rate quality ratio setting, end-of-sale promotion settings, multi-track configuration, original painting, Digital Theatre System (DTS) or Dolby transcoding.

In step S11, the video file to be transcoded is obtained according to the storage path.

The storage path is parsed and downloaded from the corresponding storage path to the video file to be transcoded.

In step S12, the first attribute information of the video file is acquired, and the video file is transcoded according to the first attribute information and the transcoding configuration information.

The first attribute information includes audio and video encoding format, audio and video code rate, total file rate, audio and video duration and total duration, audio sampling rate, and encapsulation mode of the video file, to reflect current audio and video attributes of the video file. . Then, the video file is transcoded according to the transcoding configuration information in the transcoding task data, and the finished file corresponding to the transcoding configuration information is generated.

In step S13, the result information of the transcoding task is returned to the transcoding control device.

If the transcoding process is successful in step S12, the message that the transcoding task has been successfully executed is returned; if the transcoding process fails, the message that the transcoding task fails to be processed is returned, and the execution result of the transcoding task is notified to the editor.

In this embodiment, on the basis of providing basic offline transcoding function, an easy-to-expand customization requirement is provided, and an editor can set attribute parameters for the transcoding task, and flexibly implement various transcoding functions to meet Internet users. Various video needs.

In an embodiment, step S12 may be further implemented as the following steps S120-S122.

In step S120, the first attribute information of the video file is acquired, and according to the first attribute information, it is verified whether the video file can be transcoded.

The audio and video encoding format of the video file is obtained from the header information of the video file, and the files of different encoding formats have different file header identifiers. For example, the file header identifiers in the format of asf, wma, wmv, etc. are “30 26 B2 75 8E 66 CF 11 A6”, the file header of the avi format is identified as “41 56 49 20” and so on.

The offline transcoding system presets a list of encoding formats that cannot be transcoded, and matches the audio and video encoding formats of the video files to determine whether the video files can be transcoded.

In step S121, in response to the video file being transcoded, the video file is transcoded according to the transcoding configuration information.

If the audio and video encoding format of the video file does not appear in the preset list, the transcoding can be performed and processed according to the transcoding configuration information.

In step S122, in response to the video file being unable to be transcoded, the transcoding task is exited and the verification information that the video file cannot be transcoded is returned to the transcoding control device.

If the audio and video encoding format of the video file appears in the preset list, the transcoding processing cannot be performed, the transcoding task is exited, and the verification information that cannot be transcoded is returned to the transcoding control device to notify the user that the A user is an editor or developer who uses a transcoding control device.

In this embodiment, the audio and video encoding format of the video file is verified before the start of the transcoding process to determine whether it can be transcoded. If the transcoding cannot be transcoded, the reason why the transcoding cannot be transcoded is returned to the transcoding control device. Prompt editor or developer.

In one embodiment, in one embodiment, step S12 may be further implemented as the following steps S123-S124.

In step S123, the first attribute information of the video file is acquired, and the video file is verified to be complete according to the first attribute information.

Obtaining the length of the file after the video file is packaged by the method of transcapsulation, and comparing with the total duration information of the video file in the first attribute information, if the length of the file after the package is smaller than the total length of the video file in the first attribute information The duration determines that the video file is incomplete.

In step S124, in response to the video file being incomplete, the verification information that the video file is incomplete is returned to the transcoding control device.

If the video file is incomplete, the transcoding will continue, but the incomplete video will be returned to the transcoding control device, and the editor or developer has been notified to consider whether it needs to be replaced with another video file for transcoding. .

In this embodiment, the integrity of the video file is verified before the transcoding process, and when the video file is incomplete, the verification result can be notified to the editor or developer.

The verification of the correctness of the video encoding attribute in the above steps S120-S122 and the verification of the video integrity in steps S123-S124 can also be simultaneously performed in parallel, and all the verification results are fed back to the transcoding control device, and the editor has been informed.

In an embodiment, step S12 further includes the following steps S125-S126.

In step S125, the video file is transcoded according to the first attribute information and the transcoding configuration information, and the transcoding task is monitored in real time to determine whether the transcoding task is in an abnormal state.

After the transcoding task starts to execute, monitor the running status of the transcoding task to determine whether the transcoding task has an abnormality. Monitoring of transcoding tasks can include progress monitoring and memory usage monitoring.

The progress monitoring is to monitor the current progress of the transcoding task, redirect the standard output of the transcoding program to the preset file, and read the number of frames, duration and file size of the transcoding from the preset file, according to The duration of the source video file predicts the remaining time of the transcoding, and returns the current progress information to the transcoding control device for editing by the editor.

When the progress card of the transcoding task exceeds the preset threshold for a certain value duration, it is determined that the transcoding sub-process is stuck, and the transcoding task is in an abnormal state.

Memory usage monitoring is the monitoring of the memory usage of the transcoding task. The amount of memory occupied by the transcoded subprocess is obtained according to the process identifier (pid) of the transcoded subprocess. When the usage exceeds a preset threshold (for example, when 40% of the system memory is exceeded), it is determined that the transcoding task is abnormal.

In step S126, in response to the transcoding task being in an abnormal state, the transcoding task is ended.

In this embodiment, while performing the transcoding task, the running status of the transcoding task is monitored, and the progress information is fed back to the transcoding control device, and when the transcoding task is stuck or the system resource occupancy is too high, the determination is transferred. The code task is abnormal and ends the transcoding task.

In an embodiment, step S12 further includes the following step S127 on the basis of including steps S125-S126.

In step S127, the transcoding task is reprocessed by the preset retry transcoding scheme according to the error type corresponding to the abnormal state.

The corresponding retry transcoding scheme is preset for different error types, and the preset retry transcoding scheme can be set by a workaround parameter, such as the "--ffmpeg-workaround-bugs" parameter under ffmpeg.

If the task abnormality is ended due to the card death, the audio and video encoding format of the output file may be re-encoded, for example, the video encoding is converted from the avi format to the rm format, and the audio encoding is converted from the mp3 format to the FXA. format.

If the task is abnormally terminated due to high memory usage, the code rate of the output file can be appropriately reduced, the cached data in the encoding process can be reduced, and the memory usage of the encoding process can be reduced.

In this embodiment, for the transcoding task that ends in the abnormal state, the retry is performed according to the preset retry transcoding scheme, so that the delivered transcoding task is successfully executed as much as possible.

In an embodiment, step S12 can be further implemented as the following step S128.

In step S128, the video file is secondarily encoded according to the first attribute information and the transcoding configuration information (2pass encoding)

2pass means that you need to do two encodings. The first pass encodes the whole slice first, and gets a stats file and a macroblock tree (mbtree) file. The second pass encodes the two files for reference to assign a reasonable bit rate. If a specific code rate (or file size) is required for the finished file, it is usually encoded with 2pass (or multiple pass) to ensure the quality of the transcoding, save the code stream resources, and achieve the same effect on the file audio.

In an embodiment, step S13 may further be the following step S131.

In step S131, the second attribute information of the finished file of the transcoding task is acquired and returned to the transcoding control device.

The second attribute information includes information such as audio and video duration, code rate, frame rate, etc. of the finished file, and is compared with the target code stream version of the transcoding task, and outputs the verification result and returns to the transcoding control device for the editor to the finished product. The attribute information of the file is checked and it is determined whether the finished file is output and content is distributed.

In an embodiment, step S13 may further be the following step S132.

In step S132, the image of the finished document of the transcoding task is intercepted and returned to the transcoding control device.

Directly dividing the finished file by a first predetermined number of divisions (for example, 16 equal parts), randomly capturing a first preset number of (for example, 16) JPG images, and using the image optimization program as the first preset number of images. The score is saved, and a second preset number of (for example, 8) JPG images with higher scores are saved and returned to the transcoding control device for the editor to visually view the image quality of the finished document.

Or, during the transcoding process, randomly selecting a first preset number (eg, 16) of pictures in the first predetermined number of (eg, 16) partitions to intercept the YUV color space data and saving the data in the transcoding directory, YUV color space data is transcoded into JPG format, and then the image is optimized to score a first preset number (for example, 16 images), and a second predetermined number of (for example, 8) JPG images with higher scores are saved and Return to the transcoding control device for the editor to visually view the image quality of the finished document during the transcoding process.

The above steps S131 and S132 can also be processed in parallel at the same time, and the attribute information of the finished file and the image are returned together to the transcoding control device, and the editor combines the attribute information and the intercepted image to comprehensively consider the transcoding effect to determine whether the finished document is to be processed.
