Indeo Video

Indeo Video is a video codec. Indeo is still a widely used codec, despite the release of DivX.

Compatability

Template:Unsupported VLC supports Indeo Video 1.0 - 3.0. VLC does not support Indeo Video 4.0 or 5.0 (see below).

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?
I can't look them with VideoLan or is there something I can do?

(BTW, I can't play the games either) --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 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)."
