Does Quicktime play them ? If not they are broken files. > This was my fear as well. Also, we currently default the ID for a new > stream to be the number of streams now in the list.

Lacking a tkhd is a broken file, and I know that FFmpeg has a policy of trying to play broken files. Now the good thing is that mp4 is supported everywhere and many other demuxer just refuse to play broken files :) The main issue with this new field is that it really looks like a hack. They are also many atoms that are not supposed to appear twice in a file and can break the code down the flow, so should we add “has_<atom>” for all of them ? "st->id" is not necessary for demuxing AFAIK, please correct me if Im wrong. Would an init value to -1 for st->id work ?
