GDB trace of mplayer -vo gl:yuv=6
Using mesa-7.5 on two r300 cards:
- one xpress200 (aka RS380) (IGP)
- one Radeon 9600 (RV350 AP) (PCIe)
I got mplayer segfaulting in r300_state.c:r300SetupTextures() when rendering
though OpenGL.
I tested a lot of files. I tested both gl and gl2 mplayer drivers.
Aka I used the following commands:
mplayer -vo gl:yuv=6 foobar.avi
mplayer -vo gl2:yuv=6 foobar.avi
See attached log.
The interesting bits concerning the used shader are:
OPTION ARB_precision_hint_fastest;TEMP coord, coord2, cdelta, parmx, parmy, a,
b, yuv;TEX yuv.r, fragment.texcoord[0], texture[0], 2D;TEX yuv.g,
fragment.texcoord[1], texture[1], 2D;TEX yuv.b, fragment.texcoord[2],
texture[2], 2D;TEX result.color, yuv, texture[3], 3D;END
