 Posted: Fri Feb 03, 2023 2:54 am Post subject: OBS studio AMD hardware encoder through amf |
 |
|
Hey guys,
It seems that I could'nt get to work HVEC or amf hardware encoding to work properly.
As per wiki, amf use flag only through ffmpeg.
On Arch, I have installed obs-studio-amf through AUR and I can choose AMD hvec and it is recording really well.
On gentoo though, there is no option for amd hardware encoder. Am I missing something?
TIA

amf only works with amdgpu-pro  - IIRC
from obs-studio-amf https://aur.archlinux.org/packages/obs-studio-amf
| Code: | Dependencies (32)
amf-amdgpu-pro |
and from media-video/ffmpeg ebuild
| Code: | RDEPEND="
amf? ( media-video/amdgpu-pro-amf ) |

after enabling amf on ffmpeg, it is naturally pulling the amd-gpu-pro drivers.
on wiki AMDGPU-PRO page, drivers available are
| Code: |
https://wiki.gentoo.org/wiki/AMDGPU-PRO
media-video/amdgpu-pro-amf
dev-libs/amdgpu-pro-opencl
media-libs/amdgpu-pro-vulkan |
in which I have both except the opencl
| Code: | [ebuild R ] media-libs/amdgpu-pro-vulkan-22.20.3.1462318::gentoo ABI_X86="(64) -32" VIDEO_CARDS="amdgpu" 0 KiB
[ebuild R ] media-video/amdgpu-pro-amf-1.4.26.1462318::gentoo 0 KiB
Total: 2 packages (2 reinstalls), Size of downloads: 0 KiB |
I have launched as well obs using

| Hmmmm (nevermind)... Thought I had encoded a video using the AMF encoder with ffmpeg on my system when I had Arch Linux installed... but I can't go back to verify if it had pulled in the propietary drivers or not. |

I believe there were some work arounds before obs officially support amf... now that obs officially support, it should be able to use x264 or x265(hvec) hardware encoder...

On closer look...
AMF is not enabled for Linux in the OBS source.
The obs-studio-amf package in arch linux's aur contains a patch '7206.patch' to add it in. You can clone the git repo for the aur package to grab the patch. |

Wow thanks for looking.
after getting the patch, how can I apply it? Is there a wiki or guide that I can look into?
TIA
edit:
Nevermind found how to apply patches
unfortunately

Honestly no... do I have to?
Anyway, I saw that there is a new update today. Perhaps one of the devs can just add another use flags to obs-studio like like amf for example....
Ive got to be honest, this patches is too much for me lmao.... I hope that some Gentoo amd - obs user can figure it out how to enable the amf functionality

I doubt we'll see a USE flag for AMF until the feature is supported upstream.
I had yet to patch an ebuild... so I decided to give a try. I found this video to be helpful in understanding patch: https://www.youtube.com/watch?v=yIU92YySlW0
I created a local repo and copied the ebuild for media-video/obs-studio-29.0.0-r1
I cleaned up the patch, added it to the ebuild, and installed the patched package. It seems to work. I can use the AMD hardware encoder for h264 in OBS. I don't see the hevc encoder here, however I can't use the hevc_amf encoder in ffmpeg either. I believe my GPU might be a little too old for hardware hevc encoding (RX 580). The patch also enables building of an obs-amf-test binary from the OBS source. That test tells me that I don't have AMF hevc support as well.
Here's a pastebin for the patch if you're interested: https://pastebin.com/aPDNZWJK |

Indeed, very likely when/if the upstream pull request 7206 [1] gets in.
1. https://github.com/obsproject/obs-studio/pull/7206

Thanks alot for sharing. Gonna be busy trying to figure out but its great you gave me some idea and what to look at
Never done patching nor creating and local ebuild before so gonna took some time for me
