[FFmpeg-user] Bad keyframes when encoding to the ogg container format

[Robert McIntyre]

I updated to the latest version of ffmpeg and re-encoded my video, but
I still get the error message "[ogg @ 0x121f2a0] Broken file,
keyframes not correctly marked."

this is using the test-images at:
http://aurellem.org/test-pics.tar.bz2

the encoded video is here:
http://aurellem.org/out-37806.ogg
(this is a 2 second video again, just to show that the error message
is still there)

Should I still be seeing the message "[ogg @ 0x121f2a0] Broken file,
keyframes not correctly marked." using the latest ffmpeg?

sincerely,
