4 concatenated fragments of MP4 file, without file header

Hello,

I am currently working on a smooth streaming source plugin for Gstreamer.
This plugin fetches mp4 fragments (a moof box + its mdat box) from a smooth
streaming server and gives it to qtdemux.
To verify it could be done this way, I asked on the #gstreamer IRC channel, and
someone told me it should work.
As an example, I downloaded 4 fragments, concatenated it to a single file, and
tried to play it with gst-launch (with playbin2 or made the pipeline by hand:
"gst-launch-0.10 -v filesrc location=movie.mp4 ! qtdemux ! queue ! ffdec_vc1 !
fakesink"

With playbin2, decodebin2 thinks the source has "image/x-tga" as caps.
With pipeline made by hand, it tries to parse the mp4 file header (ftyp, moov,
...) but doesn't find it, and complains it doesn't find any streams.

You can find the 4 concatenated fragements to the single file movie.mp4 in
attachment.

Gstreamer version is 0.10.34, and gst-plugins-good is 0.10.29.

Cheers,
Christophe Dongieux.
