Hi, first post on this list. I run a small game development company specializing in casual Windows/Mac games. We've been using Theora for video playback inside our engine for a while, but we always run into performance issues. I've tracked them down to two parts : YUV to RGB decoding (done via software) and uploading the new pixel data to the video card as a texture. For the YUV to RGB

...Assignee: nouveau at lists.freedesktop.org Reporter: kungfujesus06 at gmail.com QA Contact: nouveau at lists.freedesktop.org When using an NV43 based GPU on a PPC64 kernel with a 64 bit userspace, it seems applications will have byte swapped textures when specified with GL_RGBA and GL_UNSIGNED_BYTE. Matplotlib will do this when blit=True for the plot routines, and several games will have this issue. In particular, for Legacy Doom, I've found that if I swap the textures so that they are A,B,G,R just before the textures are mapped, everything is correct. I also fou...

This patchset applies some minor fixes to renouveau.xml and then unifies the nv30 and nv40 register definitions. nv30 and nv40 are very similar and have the same offsets for the registers they share. The major differences are: 1. Texture setup is different due to full NPOT support on nv40 2. More advanced blending/render targets on nv40 3. NV30 has fixed function registers, which NV40 lacks The
