-> DVD Ripping -> mencoder : my command doesn't work | | n2turtles posted 2009 Nov 05 14:13 | Hello,
I'm trying to rip my DVDs into mkv file using only free codec. To confirm the stereotype of the linux user, I want to do it in command line. I've found mencoder which seems to be exactly what I need.
So I extract the video file :
mplayer -dvd-device /dev/hda -dumpstream dvd://1 -dumpfile myfile.vob
I've already extracted the two audio channel and subtitles I wanted and now I want to do the audio.
As I read on the net x264 seems to be a nice codec. I've read the Mplayer's manuel and made this command line
mencoder myfile.vob -o myfile.avi -ovc x264 -x264encopts subq=1:frameref=1:vpass=1 -nosound
here is the output

Try appending the scale filter to your filter list,

thank you
| | Soopafresh posted 2009 Nov 05 14:44 | try mp4 instead of avi for the output
| | n2turtles posted 2009 Nov 05 15:05 | thank you for your answer but it doesn't change anything
I think I've found
mencoder video.vob -o video.avi -ovc x264 -x264encopts subq=1:frameref=1:pass=1:threads=auto -nosound
instead of
mencoder video.vob -o video.avi -ovc x264 -x264encopts subq=1:frameref=1:vpass=1:threads=auto -nosound
What's the difference ? With some commands I see that "pass" is used, "vpass" with others...
About the extension : does it really matter what I write ?
Because "-o video.avi" or "-o video.mp4" or even "-o video.abcd" seems to produce the same file
edit : ok now let's do the second pass
mencoder video.vob -o video.avi -ovc x264 -x264encopts subq=6:frameref=15:pass=2:threads=auto -nosound
doesn't work either

So there is this error "constant rate-factor is incompatible with 2pass" but I read that for a constant rate factor, I've to use the parameter "--crf"
