[MPlayer-users] MEncoder not able to crop a video when reincoding

[Thomas Kempkes]

Hi there,

I habe a problem with mencoder. I can't use the crop function to crop
some ugly black borders.
I used the latest cvs version from this morning. I did:

./configure --enable-debug=3 --enable-gui --enable-largefiles --cc=gcc-3.4.1

make

sudo make install

Is this a problem of me (since mencoder tells me "The selected video_out
device is incompatible with this codec.") or a problem of mencoder
(which should not crash anyway, I suppose)? I wanted to transform the
film to be able to view it on my Palm Tungsten T3 with MMPlayer from
http://www.mmplayer.com/ which would fit perfectly if only I could crop
the black borders. A pure scaling to 320x320 pixel works fine, but since
I have a larger display I want to have it with a width of 480 pixel.
Should I try other options? MMPlayer supports

Video codecs H263
             MPEG 1,2,4
             DivX
             MJPEG

Audio codecs MPEG audio (layer 1,2,3 -aka MP3-)
             AAC
             Ogg Vorbis
             PCM

on the palm. Other options I should try to get a cropped version playin
on my palm?
Thank in advance!
