    Can't find libx264 or libxvid

    I'm using mencoder to encode a DVD on my computer (reading it is not an issue), and I'm having trouble getting the codec to read a certain library.

    My command includes these options:
    Code:
    -ovc lavc
    -lavcopts vcodec=libx264 (I also tried with libxvid)
    It spat out this error at the end:
    Code:
    Cannot find codec 'libxvid' in libavcodec...
    Couldn't open video filter 'lavc'.
    Failed to open the encoder.
    
    Exiting...
    Unless I can get this working I'll fall back on mpeg4 but I would like these codecs. I've had good experiences with them. I've checked and the libx264-98 package is installed, along with libxvidcore4 and avifile-xvid-plugin

    Is this a permission problem? Or do I have to set a conf file?

    DO NOT suggest using a different -ovc or vcodec. If you have one that works for you, keep that for yourself. I am going to use lavc.

    This isn't really life or death here. I'd just like it to be able to work!

    Re: Can't find libx264 or libxvid

    AFAIK this error is related to the stripped libavcodec, format

    If you add medibuntu ppa (& load the key) in synaptic & then reload.

    libavcodec format util etc should be replaced with unstripped "extra" packages.

    You could also install w32-codecs or w64-codecs & libdvdcss.

    Search ubuntu website for restricted formats & medibuntu for clear instructions.

    Now it gives me this:

    Code:

    It is strongly recommended to use presets with x264 (libx264) now.

    The error is telling you the mencoder options for ffmpeg, you are using, are invalid now for x264.

    Mencoder uses ffmpeg & w32-codecs w64-codecs & other stuff AFAIK.

    I think mencoder is deprecated in favour of using mplayer directly.

    There is loads of web info about mencoder x264 presets etc..

    A typical use of x264 presets with MEncoder could be:

    Code:
    -ovc x264 -x264encopts preset=slow:tune=film:crf=22

    You think that's air you're breathing now?
