Comment (by cehoyos):

 Replying to [ticket:2918 nealzebub]:
 > Attempting to transmux an MP4 file downloaded from Facebook to mpeg-ts
 or HLS stream results in an an invalid stream.  By invalid, I mean an
 mpeg-ts file or pipe stream is produced that FFmpeg itself cannot use.

 I tried to remux the mp4 file you attached, and the output stream plays
 fine here with ffplay and can be transcoded with ffmpeg. Could you explain
 (again) what is wrong with the output file?
