I am sure there are many other ways to do this. However, I do it on a regular basis using the "mencoder" (the encoder made by the guys who made the best media player, mplayer). Also, I would highly recommend using XVid, not only because it's open source, but because the compression to quality ratio is pretty damm amazing. I have tried this procedure with mpeg2 stream files from SVCDs, .iso's of SVCDs(mpeg-2), .bin (the format made popular by CDR-Win) files of SVCDs. It has worked wonders for me. Hope it does the same for you.
I've been playing around with mplayer and mencode for the past two days now. I had a few more questions on this.
If I have an MPEG-1 (VCD) file and encode it to MPEG-4 (DivX) format, will the file size reduce?
Or do I have to pass some parameters for it to reduce in size?
Also why is it that the MPEG-4 file is generated as an AVI?
Should it not be an mpeg file?
What's the funda here?
I just started to run the following command
mencoder -vcd 2 -ovc lavc -lavcopts vcodec=mpeg4:vpass=1 -oac copy -o disk_01.avi
It's 52% done but it says
Selected audio codec: [mp3] afm:mp3lib (mp3lib MPEG layer-2, layer-3) Selected video codec: [mpeg12] vfm:libmpeg2 (MPEG 1 or 2 (libmpeg2))
So what does this mean?
Am I going to get the same MPEG 1 file at the end of this encoding procedure?
I get to understand that mp3 has some patent issues and thus it would be better to use ogg vorbis. How does one select that codec to encode the file?
Acording to the documentation I'm supposed to run this command after the one above completes
mencoder -vcd 2 -ovc lavc -lavcopts vcodec=mpeg4:vpass=2 -oac copy -o disk_01.avi
is that true?
