    Question Can't play mkv in precise

    Hello guys. Are any of you able to play mvk files in Ubuntu Precise?

    I get this error in Totem:

    "An error ocurred.

    Could not find GStreamer caps mapping for FFmpeg codec 'h264', and you are using an external libavcodec. This is most likely due to a packaging problem and/or libavcodec having been upgraded to a version that is not compatible with this version of gstreamer-ffmpeg. Make sure your gstreamer-ffmpeg and libavcodec packages come from the same source/repository."


    It mentions libavcodec,
    The libavcodec that I have installed is fromt the standard universe repository: libavcodec-extra-53, version 4:0.8.1ubuntu1

    I see that there is another one called "libavcodec53". What is the difference between libavcodec53 and libavcodec-extra-53 ? Ubuntu-restricted-extras seems to install the latter.

    I tried to use both libavcodec53 and libavcodec-extra-53. None works.


    gstreamer-ffmpeg dosn't seem to exist in the repository.


    EDIT: I cannot play it with Totem, but I can play it with VLC.

    I added medibuntu, but gstreamer-ffmpeg is not there [yet?].


    Well, I will mark this thread as solved for now since I was able to play the file using VLC.
    But, I am worried that Ubuntu's default media player cannot play this format.

    Is this a bug or simply Totem's limitation?
    Could there be a solution?

    The one file that I can locate on my system with a ".mkv" suffix plays okay with totem, vlc, and banshee.

    As I recall, mkv is not a codec, but a wrapper format that can contain encoded videos of various sorts, so whatever the error is, it doesn't necessarily have to do with a missing codec.

    Your right. I use handbrake and the H.264 for the video encoding. I tried VP3 just to see what its all about, but it compresses too much. I prefer H.264.

    VLC plays anything I through at it so far.

    The file that I tried to play seems to be a H.264 inside mkv.

    Try mplayer2 with smplayer in the repos.
