You can convert your sample with:
$ ffmpeg -flags2 +showall -i vid.h264 vid.mp4
(MPlayer always sets showall to speed up seeking.)

Before I open a ticket:
Could you elaborate how (exactly) you captured 
the stream? Is FFmpeg able to read frames 
directly from the camera? Or does this also 
need "-flags2 +showall"?

Thank you for the sample, Carl Eugen
