[MPlayer-users] mencoder and -vop expand

[Kiko Piris]

Hi all,

I have a video that I would like to resize (not rescale but expand, in
order to be able to transform it to SVCD).

Original video size is 672:288.

I've used the option -vop expand=704:576 in mplayer and it plays fine
with the black bands on top and bottom.

My problem is with mencoder, I've tried the following :

mencoder input.avi -oac copy -ovc copy -vop expand=704:576 -v > output.log

And the generated test.avi continues to have the same format than the
original.

I've tried placing '-vop expand=704:576' in different places in the
command line, I've searched the docs, the web, and the list archives
with no success at all.

Could anyone tell-me what I'm doing wrong ?

Here follows the output.log contents:
