AMD Adds Gallium3D H.264 Profile Encoding Support
Phoronix: AMD Adds Gallium3D H.264 Profile Encoding Support
AMD's Leo Liu has published a set of four patches that improve Gallium3D's video support, particularly around H.264 encoding for Radeon GPUs...
The Force is strong in them.
AMD have been going nuts on Linux drivers lately.
good thing commin
I thought GPU-assisted encoding wasn't practical.
Or was that just OpenCL encoding?
Which engine on the GPU is being used?
The most recent chips have dedicated Video Compression Engine (VCE) hardware. Sometimes called Video Coding Engine or Video Codec Engine, depending on who you ask.
I have a 7730M. Assuming it can do this since it's GCN, what can I expect compared to an 3632QM or any other sufficiently powerful CPU?

Is there somebody who can confirm this problem?
GPU encoding has been possible for a good while now, theres a tradeoff thoguh, the quality and file size and range of encoding options are limited by what the VCE can do, but it can do it very quickly.

I haven't looked at benchmarks for it in a while, but I remember older $100-120 GPUs(HD4000 era I think) where able to transcode a video faster then whatever the current $1200 Intel Extreme Edition CPU was current.
Is there any progress on UVD 2.0 and earlier?
Not going to shift any priorities, only curious.
