I uploaded the files "20090202 Mplayer first frame is no keyframe test.mp4"
and "20090202 Mplayer first frame is no keyframe test.txt".

The explanation again:

"20090202 Mplayer test.mp4

The clip is encoded with iMovie '08 (v7.1.4.) under Mac OSX. I used the
following options: "Export using QuickTime" feature, Movie to MPEG-4, "video
format" H.264, bitrate 2000, framerate 25, keyframe: automatic, optimized
for CD/DVD-ROM.

The resulting clip plays nicely under MacOSX's QuickTime player (v7.6) , but
when I try to play them with mplayer either under Mac (v1.0 rc2) or Linux
(Debian, v.dev-SVN-r25315, or dev-SVN-rUNKNOWN-4.2.3), I get the error
"first frame is no keyframe". The clip is played, but the first few seconds
are garbled."

Thanks,
   tc.
