H.264 decoding is already done on GPU shaders, mind you. Most recent example is Blu-Ray 3D decode on 6770 with the proprietary driver, whose UVD unit is not capable of handling two HD streams simultaneously.

I have read that UVD on JUNIPER can only decode 1 HD + 1 SD stream simultaneously (for Blu-Ray PIP). In order to decode 2 HD streams on the 6770 (for Blu-Ray 3D) some sources claim that shaders are used[1] while others say that the UVD clocks are simply increased[2].
