Importing mp4 with several mdat atom boxes
It seems that tsMuxer is not able to read 5.1 ac3 encoded audio... I tried to demux several mp4 files with 5.1 ac3 audio and tsMuxer did note open them, but no errors.
Bizarre... No problems on my side. Please provide a link to a problematic mp4 (sample < 50 MB).
It's really strange... The original clip has 299MB corresponding to 2' 29". For give you a part with aprox. 40MB I used MP4Box and splitted the clip. When importing any of the splitted clips all were read by tsMuxer. I observed that MP4Box altered the splitted clips because the bitrate became smaller... I leave here the link to the original clip (299MB) that I can't open. If you can download it...

Thanks for you collaboration to all of us.
@bairradino thanks for the link: it is an interesting mp4 with several mdat (media data) boxes, which is allowed by the ISO standard but rather unusual for non-fragmented mp4. tsMuxer does not cope yet with these kinds of mp4, I'll try to see if I can make it work when I have time.
@bairradino Unfortunately too complicated for me. tsMuxer currently processes mp4 having a single mdat with interleaved track chunks/samples, however your mp4 has a separate mdat box for each track (audio and video). The changes to be made to tsMuxer are above my coding capabilities... Until somebody pushes a fix, you can simply remux the mp4 with ffmpeg or mp4box before processing with tsMuxer.
Could you please rename the title to "Importing mp4 with several mdat atom boxes".
