  cbs : Add some read/write tests
  Use the appropriate metadata filter for each codec - in the absence of any
  
  options to modify the stream, the output bitstream should be identical to
  
  the input (though the output file may differ in padding).
  All tests use conformance bitstreams, the MPEG-2 streams are newly added
  
  from the conformance test streams

• Why the audio of my mp4 file is going out of async

  16 juillet 2018, par Dop

  I am having a problem converting a wmv file to mp4. I am using x264.exe this command to get the video stream

  x264 --output temporal.264 --fps 25 --preset slow --bitrate 2048 --vbv-maxrate 2048 --vbv-bufsize 9600 --min-keyint 48 --keyint 48 --scenecut 0 --no-scenecut --pass 1 --video-filter "resize:width=640,height=480" Original.wmv

  Then I use ffmpeg.exe to extract the audio stream with this line :

  ffmpeg -i .wmv -acodec libfdk_aac -b:a 32000 temporal.aac

  finally I use MP4Box to merges each stream with this line :

  MP4Box -add temporal.264 Final.mp4
MP4Box -add temporal.aac Final.mp4

  The problem is that the final.mp4 audio is out of sync. It starts good but with time it goes out of sync with time.

  I run this command :

  MP4Box -info 010004470063PE-10022017083824-2_MultiMedia--1.mp4

  and I discover that the estimated time of both streams are different :
