Public bug reported:
Binary package hint: libgl1-mesa-dri
Using Jaunty with Mesa/DRI drivers, Elisa displays video with
greenish/purplish colors, it was working in Intrepid.
In Elisa, the video playback is done by the Pigment library which uses
an OpenGL fragment program to do fast color space conversion from YUV to
RGB. The fragment program uses 3 luminance textures containing the Y, U
and V planes. For each rasterized fragment, the fragment program fetches
the values from the 3 textures, computes the resulting RGB color, and
stores it as fragment color.
The Mesa version used in Jaunty contains a bug making that fragment
program output wrong colors. I just tried the last revision from the git
repository and the bug is not there anymore. I'll try to bisect to get
the right fix. It would be nice to get that back-ported to Jaunty
because that's quite critical since Elisa can't be used to watch videos,
which makes it a really useless media center. By the way, that bug is
certainly breaking other programs using 3D acceleration through OpenGL
and fragment programs.
