is there a program that can extract the content of an mkv file to be combined later

i have some mkv files that come out pixelated and i don't want to go through the trouble of finding a suitable media player so i want to extract the desired audio channel and video channel to combine them into an avi file that will hopefully be playable on most media players

i already have mkv-toolnix installed but i see nothing that will extract the contents of an mkv or as far as i know i think it's though command line. and how would you combine the audio and video together

is the pixalation the normal mostly green with some red and blue added and all jumbled up ?
if so it is encrypted and you would need some odd proprietary codec from whomever made it . Check the web site of the content creator

i just extracted it from the mkv file and the video comes out mpeg and when i play it in anything it goes really fast and i can't put it in avidemux to slow it down. i extracted it with mkvextract but here are the tracks after running mkvmerge

Code:

$ mkvmerge -i movie.mkv
File 'movie.mkv': container: Matroska
Track ID 1: video (V_MPEG4/ISO/AVC)
Track ID 2: audio (A_AC3)
Track ID 3: audio (A_AC3)
Track ID 4: subtitles (S_TEXT/ASS)
Attachment ID 1: type 'application/x-truetype-font', size 97080 bytes, file name 'LT.ttf'
Chapters: 15 entries

and this is what i ran to get the video

Code:

$ mkvextract tracks movie.mkv 1:video.mpeg
Extracting track 1 with the CodecID 'V_MPEG4/ISO/AVC' to the file 'video.mpeg'. Container format: AVC/h.264 elementary stream
Progress: 100%

and since it's an mkv it doesn't play nice with vlc which is what i used to play it but i have read that mplayer plays mkv files more smoothly and it worked but i still want to make it into an avi file format

hi there.
i recently converted a dvd iso file with a movie on it to ogg compressed to 700MB.

i looked at the log file and through it i found this command that it used to combine the audio and video together .

maybe starting from this would another more experienced user give the corrent command ... i think it is for ogg . please anyone say for avi ...

Do you have ffmpeg installed?
Example:

Code:

ffmpeg myfile.mkv -b 2000k -ab 128k -s wvga -ac 2 -acodec ac3 myfile.avi

Look at man ffmpeg

There are lots of options to choose from
