    Hi!
    Mencoder is working perfect for multiplexing video both with ac3 and wav but why will the resulting video only play back descently in mMplayer? The utility VlcMediaPlayer is playing only the sound without visuals and WombleMpgEditor only shows the video without audio. WindowsMediaPlayer shows nothing at all and complains for not finding the codec. My settings are:
    mencoder -ovc copy -oac copy -audiofile C:\Sound.AC3 C:\Video.MPG -o C:\Output.mpg

    Question: Which codec is needed for playing the video normally in VlcMediaPlayer etc.


    Thanks in advance// Christer Holmberg

    I would try multiplex with mplex and see if it works better.

    Can windows media player play other mpeg2 files fine?

    Answer 1) Yes thankyou, mplex did a great job for me muxing video.mpg and audio.ac3. Sadly mplex ignores CBR160.mp3 and 44100.wav.

    Answer 2) Yes, Windows Media Player is able to play other mpeg2-files fine including VOB-files.

    I have great respect for mencoder but now it seems like I have to use a lot of other utilities.

    My first question still remains unanswered.


    Thanks Baldrick for helping this far// Christer

    WARNING: OUTPUT FILE FORMAT IS _AVI_.
    Check in GSpot.

    Try...
    Code:
    mencoder -of lavf -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames:format=mpg -ovc copy -oac copy -audiofile sound.ac3 video.mpg -o output.mpg
    or
    Code:
    mencoder -of lavf -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames:format=mpeg2 -ovc copy -oac copy -audiofile audio.ac3 video.mpg -o output.vob

    VLC not use external codecs - only internal.
