I would love to give the part of the original stream if I could find the
byteposition of the problematic part. But getting out the h264 part with current
ffmpeg already fails terrible. It identifies the stream as 26.65fps. After
several minutes still no 150 frames. An older version SVN-r17923 produces the
frames in a fraction of a second.
