• FFmpeg : Parallel encoding with custom thread pool

  13 novembre 2017, par ZeroDefect

  One of the things I’m trying to achieve is parallel encoding via FFmpeg’s c API. This looks to work out of the box quite nicely ; however, I’ve changed the goal posts slightly :

  In an existing application, I already have a thread pool at hand. Instead of using another thread pool via FFmpeg, I would like reuse the existing thread pool in my application. Having studied the latest FFmpeg trunk docs, it very much looks possible.

  Using some FFmpeg sample code, I’ve created a sample application to demonstrate what I’m trying to achieve (see below). The sample app generates a video-only mpeg2 ts using the mp2v codec.

  The problem I’m experiencing is that the custom ’thread_execute’ or ’thread_execute2’ are never invoked. This is despite the fact that the codec appears to indicate that threading is supported. Please be aware that I have not yet plumbed in the thread pool just yet. My first goal is for it to call the custom function pointer.

  I’ve tried to get assistance on the FFmpeg mailing lists but to no avail.

  As seen from the screenshots there are 14 frames of difference, and later rise to 35

  Can frames be damaged and ffmpeg skip them ?

  The video for the first 13 minutes is perfectly synchronized

  FinalOutput.mpeg has the same frames as output.mpeg
  I have several TransportStreams to process and everyone has a frame difference

  someone can help me to solve the problem ?

  I need FinalOutput.mpeg to be aligned frame by frame with the original and necessarily the video must impress the timecode.

  a possible solution would also be a replace "damaged" frame but I can not find out how to replace the skipped frames

  EDIT :

  i’ve tried to work from OriginalVideo.ts and extracted video with -map directly with FFMPEG but the result is the same

  CL : ffmpeg -i OriginalVideo.ts -map 0:0 -c:v copy output.h264
