convert rmvb to avi

[sunny]

In this article, I am going to show how to convert a rmvb file to an avi file (mpeg4 video + mp3 audio)

Tools
1. mplayer
2. mencoder
3. essential codecs for mplayer

note: to install the above tools, please take a look to http://stanton-finley.net/fedora_cor...ion_notes.html

File
1. rmvb file: in.rmvb
2. avi file: out.avi

Information for the avi file
Video
format: mpeg4
bitrate:1200 kb/s
fps: 25 fps
Audio
format: mp3
bitrate: 128 kb/s

Command
mencoder in.rmvb -oac mp3lame -lameopts preset=128 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1200 -ofps 25 -of avi -o out.avi

Explanation
-oac: output audio codec
mp3lame: library used for audio encoding
-lameopts: options used along with lame
preset: values for audio bitrate, you can set 64, 128, 224, etc
-ovc: ouput video codec
lavc: library used for video encoding
-lavcopts: options used along with lavc
vcodec: video codec, you can use mpeg1video, mpeg4, etc
vbitrate: video bitrate, you can set 600, 1000, 1200, etc
-ofps: outpt frame per second ( fps)
-of: output file container type
-o: output filename

Mencoder is a powerful tool to convert multimedia, just like the above example, we can use it to convert rmvb to avi. With suitable library and codecs, we can even use it to convert file format like rm, wmv etc.

working on encoding an avi to vcd format.
I am fairly new to linux. i searched for alot of guides, but i have to admit that ur guide is the best i have seen so far.
i am off doing the reading the trying to understand how this encoder works.
wish me luck creating a vcd.
the only reason i had xp installed is because nero did the encoding for me, but i decided to delete the windows partion and it has been a while since i burned my own vcd. lets hope i get it done then only i will be relified and wont miss nero on xp anymore.

Thanks again

Marvelous, thanks your reply.

To create VCD from an avi files, there are 3 steps to go through:

1. avi --> mpg
2. mpg --> image for VCD
3. burn the VCD

There are various method to finish step 1, one of them is using mencoder. The details is described in the following link:

http://www2.mplayerhq.hu/DOCS/HTML/e...t-vcd-dvd.html

What I prefer is using "ffmpeg" as it is fast and command is simple. Here is the command I use to create mpg file:

ffmpeg -i input.avi -target pal-vcd output.mpg

note: above is for pal-vcd, if you want ntsc standard, replace "pal-vcd" by "ntsc-vcd"

For step2, a tool called "vcdimager" is needed, command is as follows:

vcdimager input.mpg <---- for single mpg file
vcdimager input1.mpg input2.mpg input3.mpg <--- for multiple mpg file

Vcdimager will create 2 files ( videocd.cue and videocd.bin) for burning

For step3, a tool called "cdrdao" is needed, command is

cdrdao write --device ATA:1,0,0 --eject videocd.cue

note: to find the device ID, run "cdrdao scanbus"

I hope the above method can help, good luck.

Thats great !
its hard work getting to learn all of this, yet you made it look so simple.
saved your post and backed it up. its very easy to handle... its spoon feeding tbh.
Thanks a million you made life much more easier !
Hats off to you

check out this site, it works reasonably well http://f0rked.com/projects/simplerip the only problem i ran into was i had to change the audio codec from copy to mp3lame, and also add the appropriate lameopts from the command above, but it's just so easy and requires almost no thought

After updated mplayer and mencoder to version 1.0-0.28, I got a -vo error (cannot find match codecs) when playing rm/rmvb files. My workaround is to copy the essential codecs to

/usr/lib/codecs/

Should anyone have this problem, letś try it and see it works. Good luck.

I have the same problem, waiting for your answers...

Yeah, I'm way late on this one. Just wanted to say thanks for the help, I can finally re-encode the stuff I (foolishly?) put in rmvb back to a "normal" format. The stuff I encoded with your command wouldn't play on my DIVX player for the kids to watch on tv (worked fine for viewing on the computer of course). The solution was to encode with xvid instead (I believe xvidcore-devel needs to be installed for this to work with mencoder) with something like this:

mencoder your_input_movie.rmvb -oac mp3lame -lameopts preset=128 -ovc xvid -xvidencopts fixed_quant=4 -of avi -o your_output_movie.avi

edit: here is a helpful guide by a guy I know: http://www.pclinuxos.com/index.php?o...&topic=49481.0

Thanks for your post - you got me doing my homework over at the Gentoo wiki (is there anything those guys can't do? )http://gentoo-wiki.com/HOWTO_Mencode...oduction_Guide

I had the same problem the other day. It used to work fine. Since Feb. when I made that reply I have since switched to a 64 bit system. That is the only variable for me, so there must be a slightly different way to write up the mencoder command, or perhaps a need to symlink some of those realmedia codecs... I don't really know, so I'll be watching replies to this one...

Edit: We need to download the drvc.so, which is in the mencoder codec essential package: http://www.mplayerhq.hu/design7/dloa...#binary_codecs

Error loading dll
ERROR: Could not open required DirectShow codec drvc.so.

Edit number 2: I see Ubuntu/Medibuntu has a win64 package. Maybe we have something like that too?
