Vega GPU encode/decode features info.. #96
Comments
Was going to make a similar post, hoping @MikhailAMD will post (brag? :D) about vega's VCE details. Has B-frame support made a return? Any overall quality improvements for H264/5 over polaris VCE? |
http://pro.radeon.com/en-us/product/radeon-vega-frontier-edition/ seems to be supporting h265 only 4k60 |
At this point this link is the only public information available. Details will follow. Stay tuned. |
What does this mean ? HEVC acceleration is subject to inclusion/installation of compatible HEVC players. GD-81 |
Not sure I understand the question. |
This means that players need to use either Media Foundation or have AMF support to use HW accelerated playback. |
Thanks. OBS seems to be at the cutting edge of support for AMD encode/decode. Do you happen to know how OBS compares to gstreamer support for AMD encode/decode ? I use gstreamer a lot, and have been developing plugins there. |
@MikhailAMD this line is footnote mentioned in link provided by @M4RK22 |
OBS and gstreamer have different focus. OBS is a streaming/recording tool and gstreamer seems to be a multimedia framework. |
OK, thanks. |
From what little information has actually reached me from a Vega FE owner, the card supposedly have a new multimedia IP. If this is VCE 4.0 or not remains to be seen when the consumer oriented cards appear. |
RX Vega now unveiled, care to spill the beans @MikhailAMD? :) |
8K video decode (h264&h265)? vp9 HW decode? vp9 10 bit for YouTube HDR? and Playready 3 support for Netflix 4k? |
someone has dxvachecker of even a Vega FE with 17.20 and 17.30 drivers? |
AMD published a white paper which has details for multimedia HW blocks: |
So a nice speed bump. Are there any quality improvements or new features? Have B-frames made a return? 10-bit encoding? |
No B-frames or 10-bit encoding in this HW. |
So, once again, no VP9 fixed function decoding. VEGA uses hybrid decoding like Polaris according to that PDF. "Vega can also decode the VP9 format at resolutions up to 3840x2160 using a hybrid approach where the video and shader engines collaborate to offload work from the CPU." |
I'm assuming he can't say, but I hope they're busy on AV1 support for Navi. AMD is an AOMedia member after all :) |
I don't think he needs to say anything special or top secret. The PDF posted says everything, I think. |

"Vega can also decode the VP9 format at resolutions up to 3840x2160 using a hybrid approach where the video and shader engines collaborate to offload work from the CPU."[/quote] For AVG Joe and AVG Gamer only practical commercially sound use case scenarios make sense, so it makes no big difference on the Desktop then it does in the Mobile space where Nvidia invests first into fixed function to be the battery king. It would be a problem if Vega Mobiles UVD would be not able to handle it equally efficient (Raven Ridge) in a efficient way and it overall doesn't matter if fixed function DSP or essentially compute the power target efficiency matters. and if you weight overall architectural balance VEGA at least sounds very balanced :) But yeah they are much to few qualified reviewers to really tap into how compute plays a role supporting video decoding encoding on a low level one thing for sure AMD isn't beating Intel engineers yet on this field neither does Nvidia on the Desktop ;) Ryzen + Vega doesn't look like to have this balance but Intel + Vega and Intel + Nvidia does. And that is somehow crazy that Ryzen in all it's lineups didn't gone the same route so hopefully with Raven Ridge we gonna see a massive improvement there, and Mikhail and the other Engineers can go full Power on it ;) I really wonder how many actually understand how powerful the combination of Raven Ridge + Vega Discrete actually will be :) |
Closed as stale issue |
Hi,
today Vega Frontiers Edition is public so can AMD speak about impromevents to video encode/decode vs Polaris GPUs?
I see:
"Multi-stream hardware H.265 HD encode/decode for power-efficient and quick video encoding and playback"
All below I ask for HW acceleration of course:
supports 4k@ 60fps HEVC video encode? also 4k60 H264 encode? supports 10bit HEVC encoding?
what about VP9 decode? is now native.. not hybrid? supports VP9 profile 2 (HDR) for YouTube HDR support?
