[gentoo-user] mplayer: xvid and lavc

[gentoo-user] mplayer: xvid and lavc

[Arnau Bria]

Hi all,

I'm trying to add some sub to a video with menconder (following a
receipt).

I run something like:

mencoder mi_video.avi -oac pcm -ovc lavc -lavcopts vcodec=xvid:mbd=2:trell:autoaspect -sub mis_subs.srt -subfont-text-scale 3 -o video_final.avi

but I get the error:

[...]
Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)
==========================================================================
Cannot find codec 'xvid' in libavcodec...
Couldn't open video filter 'lavc'.
Failed to open the encoder.


I though that building mplayer with xvid support should be enough:

$ eix media-video/mplayer

Um...it is not the exact command you should use in your case with the 
subs, it is an example on how to bypass the lavc problem.
Producing a working command, that suits _your_ needs is still your job ;-).

Has this worked before? As fas a I know, AVI does not officially support srt 
subs.

If you have a problem, call your system-administrator.

It worked for me:

mencoder ITC0101.avi -oac pcm -ovc xvid -xvidencopts bitrate=886 -sub ITC0101.srt -subfont-text-scale 3 -o video_final.avi


my problem is that new video is much bigger than original. More or less
twice original. I don't know why...

My guess is that you really want -oac copy instead of pcm. PCM is 
uncompressed.
