Reading / reusing smooth streaming (fragmented ismv / isma) ?

[radius]

Hi,

I've been looking for a way to read fragmented files from a smooth streaming source, I've seen a LOT of discussions but couldn't find anything working in my case,
the source provides separated video and audio, each fragment (video or audio) starts on a "moof" like this :
...Ùmoof....mfhd...........Átraf....tfhd... ......€.....trun

I can download the fragments with urls ending like :
/QualityLevels(400000)/Fragments(video=610275114)
and
/QualityLevels(48000)/Fragments(audio=610275114)

but I couldn't find a tool that can use them (ffmpeg / mp4box / mp4split ...), do you guys have any idea for this ?

Thanks

Just found that ismdownloader2 (by dvb-crew) just does this,
it automatically downloads fragments then remux the all thing in a MKV,
by the way does anyone know how does it extract elementary streams from fragments ?
