[MPlayer-users] Corrupted last frame when using -endpos

[Robert Nichols]

When I use mencoder with the -endpos option, I find that the output
includes a corrupted frame at the end.  FWIW, I get the same result
if I use -frame to end the encoding.  My mencoder version is
1.0rc1-4.1.2.

For example, if I encode with:

    mencoder -oac lavc -ovc lavc -of mpeg -vf scale=720:480,harddup \
             -endpos 10 -o test.mpeg 4-06.avi

then I get the following when playing the resulting file with mplayer:

   $ mplayer test.mpeg

The real problem comes when I make a DVD by splicing together segments
from various AVI files.  The stream has a corrupted frame at the end
of each segment, and my DVD player doesn't like that.

Am I missing something basic here, or is this a bug?
