  avformat/mpegts.c : ignore a section with next flag
  'current_next_indicator' of 0 (next) on each section header indicates
  
  the service information is for immediate future one.
  
  ffmpeg doesn't need to parse it but current (1) one.

• How to manually reset the offset of an mp4 video created from m4s files ?

  12 août 2020, par natdev

  I'm building a service that combine .m4s files (from a dash stream) to a mp4 video.
  
I have some sample m4s files from a random point in time of a stream,
  
using ffmpeg on those file + the init file does the job.

  


  cat init.mp4 032.m4s 033.m4s 034.m4s > output.mp4


  


  I have tried concating the m4s files to the mp4 init file and I manage to play the video,
  
but there is an offset from the encoded video segments.

  


  I guess ffmpeg does reset that somehow, and I was wondering how can I reset that offset as well ?
  
Having a little bit of experience with dash, I know that there is a field name presentationTimeOffset that is responsible to set the offset.
