I'm not sure if r300 GPUs have the capability to do this, since they lack unified shaders. My guess is they can't be programmed for this task.

Still, I think it is just sad that this isn't being worked on for R300 cards, where i think it would be the most needed because CPUs from that era can't handle HD video.
I know that Gallium based stuff is supposed to be easily shared between drivers, so I hope it would simplify an eventual port to R300g.
Also, I understand that R300 is old and doesn't necessarily drags interest now, but until a few months ago I had an old pentium 4 rig that did everything I asked perfectly fine, let alone... high def video

CPU cracking BluRay encryption under Linux = even more Watts.
The system + Wifi power costs needed to download a 9GB HD movie = more than a KWh.
The extra 20W or whatever needed to decode the movie in software is a red herring IMHO.
The shaders are not the biggest problem you have if you want to legally watch HD contents. The whole video decoding problem is not technological, it is legal, and Linux will ALWAYS consume more power than Windows doing this.
There is a law which stipulates that you should be punished for watching movies on Linux. If you defeat that law, there are no technological issues left. It's not a G3D/AMD/Nvidia/UVD/h264 discussion, you are using more watts because the media industry made you.

I'm happy about the shader decoding, it's a nice tool to have, and it's a flexible solution. Personally, given the power of my CPU, I don't find it all that important for me, but it might save some people with weaker CPUs.

This is pretty cool, but I still doubt the usefulness of this. Power consumption aspects aside, if your GPU is powerful enough for accelerating HD playback, it's likely your CPU will be powerful enough to do it alone. Also keep in mind that with Gallium's partial acceleration, a fair bit of CPU power is still needed, especially with H.264.
