View source for Talk:Indeo Video

I have avi from old computer games, that i can't look. I need the Indeo Codecs, but as I see I have them already (Windows XP SP2). On your  VLC features list (http://www.videolan.org/vlc/features.html) VideoLan does not use the Indeo Codecs.

Why aren't they not supported?<br>
I can't look them with VideoLan or is there something I can do?

(BTW, I can't play the games either) --[[User:Lemmi|Lemmi]] (unsigned)

: In general, VLC ignores the codecs on your machine (the only exception, I believe, is the WMV3 codec). However, VLC does have support for  Indeo Video 2.0 and 3.0, but not 4.0 or 5.0.
: Indeo is owned by [http://ligos.com/ Ligos], who owns the rights to the Indeo codecs. 
: From the [[forum]], markfm (Developer), says:
:: "IV50 is proprietary, that's why VLC doesn't support it, VLC is an open-source, GPL project, so unless someone were to reverse-engineer Indeo Video 5, come out with an open-source implementation, it won't be in VLC.
:: "Reverse-engineering a CODEC is painful, time consuming. CODECs generally work by doing some pretty advanced mathematical operations on the video data -- various Fourier and wavelet transformation techniques, working with the video in the frequency domain, a bunch of matrix math things, various mechanisms to predict movement and only sent small blocks of data at a time (inter frames), all in pursuit of high video quality at minimal bandwidth (a lot of compression)."
