Does anyone know of a program with which I can uncompress an AVI? I downloaded several apps for windoze, but they all give me some errors that dont make sense
Could I ask why you want to do it? By uncompress, do you mean to 'convert' it to another format? Most peoples around like to convert .avi's into play-ables DVD's or VCD's. If that's what you want, any modern burner software should do it.
AVI is a wrapper IIRC. It combines a video, compressed with whatever codec the original author compressed it with, and audio, usually compressed as well. So a program to "uncompress" an AVI would be a mis-termed program. You could have an application that unwrapped the AVI (Audio/Video Interleaved IIRC), found the type of the compression used on the video, and then from there you could begin to transform it. To save that step of unwrapping though, mplayer does a great job of detecting the compression used by just playing it, you don't need to watch it even:
mplayer -vo null -ao null filename.avi
And just look at the headers.
mplayer can decompress i think, using raw dumps ..... or if decompress you mean turn it into a bunch of images use "mplayer -vo help" any of the vo options listed that sound like image formats will turn the movie into a bunch of images in you current directory
Well, my goal is to convert AVIs into rmvb (real media) files. I have a large collection of anime that is occupying a lot of disk space. By converting AVIs to rmvb, I can convert a 170MB Xvid or DivX compressed AVI into a 60MB file, with hardly any quality loss.
Now realproducer supports only uncompressed AVIs. "Uncompressed" as in without any video compression codec such as Xvid or DivX. I have found that the Intel Indeo Codec is also accepted by realproducer.
So what I want is a large uncompressed AVI file with both audio and video, something that I can convert to realplayer format.
I have tried using mplayer -vo mpegpes But I get only video, without any sound
Recompile mplayer with --enable-large-files (or something very close to that, check the --help for the exact tag). Be sure you are using a filesystem that doesn't hinder you either.
