Description

Summary of the bug: I'm trying to remux a MOV file to a TS file and ffmpeg creates a TS file without an audio track. The original file plays file with WMP 12, the TS remuxed file has no audio. This is also reflected in ffmpeg -i on the converted file, see output below.

-bsf h264_mp4toannexb is required otherwise ffmpeg throws an error

[mpegts @ 043788a0] H.264 bitstream malformed, no startcode found, use the h264_mp4toannexb bitstream filter (-bsf h264_
mp4toannexb)
av_interleaved_write_frame(): Invalid argument

How to reproduce:

ffmpeg -i ChrisWalkingZoomOnLegsGoodVideo.MOV -codec copy -bsf h264_mp4toannexb test.ts

  • Resolution set to invalid
  • Status changed from new to closed

As discussed before, you cannot put random codecs into transport streams. This is not a limitation of FFmpeg, it is a limitation of transport streams.

So instead of "successfully" finishing teh remuxing shouldn't ffmpeg throw an error?
