Found this bug report googling for ffmpeg STSC entry is invalid. Perhaps the example files provide enough information to adapt ffmpeg's isom demuxer to tolerate non-compliant files the way avidemux can. Hope these comments are useful:

  1. This problem can be reproduced with another file. It is found here

  1. Common between all three of the example files: (A) they can be opened by MPC, WMP and VLC, (B) they have isom format container, (C) they have variable frame rate video stream. Problem appears to be trouble reading malformed header of isom container, but goes deeper than the header.
  1. The Haali remuxer dsmux.exe can successfully remux the westworld file to mp4 (mp42) file that ffmpeg can ingest. However, dsmux.exe hangs when trying to remux either of the two example attachments uploaded by the OP.
  1. Loading any of the three mentioned files into avidemux v2.6 causes the "Some timing information are incorrect" warning. The user is given the choice of throwing out the timing information or not. Whatever the user's choice, with video and audio codecs set to copy and container set to mp4 (isom), avidemux will output a working mp4 file that ffmpeg can ingest.
