Hi,
I'm trying to play IIS Smooth Streaming wire files, e.g. http://ispmix1.edgesuite.net/NAB/showcase1.ism/QualityLevels(3450000)/Fragments(video=0).
They are in the fragmented mp4 format, which ffmpeg usually supports (as I have now learnt by looking at mov.c source code) however they lack a trex box/atom. Ffmpeg just complains that it can't find the trex box then quits. How can I either 1) get it to play on ffmpeg without a trex box or 2) make a trex box for this kind of video?

I've tried simply commenting out the error checking but that only results in a segmentation fault due to the parameters required that are in trex.

Thanks,
Adam
