As you observed, the nvidia driver unloads the video engines on certain GPUs when they go idle to save power. You can disable this behavior by loading the nvidia kernel module with: modprobe nvidia NVreg_RegistryDwords="RMPowerFeature=64"
Regarding your H.264 hangs, the most likely cause is mis-programming the video engine. I suggest double-checking that the nouveau driver sends the exact same parameters for each decode operation as the nvidia driver does. In particular, check that buffer alignments match up, as those m...
