obs-ffmpeg: Make AMF encoder work on Linux

Open nowrep opened this issue 3 years ago • 43 comments

Description

Add Linux support for AMF encoder. Only the fallback encoders are available (no texture support).

Requires AMD proprietary Vulkan driver, using different driver will be detected on startup and the encoders disabled.

Motivation and Context

AMF is also available on Linux and thus users on Linux should be able to use it in OBS too.

How Has This Been Tested?

Tested with RX 6700 XT using latest driver version 22.20 on Arch Linux.

VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/amd_pro_icd64.json obs

nowrep once again making awesome things happen on linux. this plugin works great.

For Nobara (Fedora) we set this up so our users can use the AMF encoder easily:

https://github.com/CosmicFusion/fedora-amdgpu-pro

I just tested your plugin on a 6900 XT and was able to record 1440p60 just fine. It should be noted that anything higher than 1440p results in a black video recording (this is a limitation of AMF -- it happens on ffmpeg directly and with the StreamFX plugin), although this may be a limitation only on RDNA2 due to this bug:

https://github.com/GPUOpen-LibrariesAndSDKs/AMF/issues/334

I'll try to test later on the full official driver stack on ubuntu

UPDATE: After digging around the pro packaging, we got h.265 to work via custom ffmpeg -- it needs amdgpu's libdrm (we packaged that today in the same repo) and opencl-filesystem from fedora repos -- these two fix the GPUOpen bug listed (ill post an update letting them know). If we can get the h.265 option added to this PR i'd be happy to test.

It checks for hevc support at runtime, you can test it manually by running obs-amf-test. It doesn't work for me, presumably because of that GPUOpen issue and having to use old vulkan driver - so no features added recently (hevc support, B-frames, ...) work on my AMF installation.

it's working here with custom ffmpeg with the options i noted -- do you have discord or something we can have a discussion about it? if you're on fedora i can help get you sorted on the amd pro driver side

I prefer e-mail or IRC nowrep at libera.chat

nowrep avatar Sep 02 '22 05:09 nowrep

Changes:

  • Try to load AMF library before running obs-amf-test
  • Fixed HEVC detection

nowrep avatar Sep 02 '22 07:09 nowrep

Just dropping in a confirmation that this works great now, worked with nowrep to get the drivers sorted on his side and everything's all good: https://www.youtube.com/watch?v=jlSEf_TPfPA

GloriousEggroll avatar Sep 02 '22 09:09 GloriousEggroll

i have perfected my amdgpu-pro repackging (what @GloriousEggroll uses in nobara) , and this plugin works well on all gpus , with 4k support on all gpus (not great on lower end ones like polaris) , and h265 on RX5XXX and RX6XXX ..

CosmicFusion avatar Sep 02 '22 14:09 CosmicFusion

Made this available as an AUR package too so more people can test it and give it some feedback: https://aur.archlinux.org/packages/obs-studio-amf

Thanks a lot for this @nowrep (And also for vkcapture)

I'm having trouble getting h265 amf to work on Arch. I installed OBS using this AUR package:

https://aur.archlinux.org/packages/obs-studio-amf

As for the proprietary drivers, I tried amf-amdgpu-pro and amf-amdgpu-pro-fix from the AUR, and my PKGBUILD which can be found here:

https://github.com/DoomPenguin9/amdgpu-pro-vulkan-and-amf-only/blob/master/PKGBUILD

With amf-amdgpu-pro, neither AMF H265 or H264 would show up in OBS. With amf-amdgpu-pro-fix and my PKBUILD, AMF h264 shows up and works, but I can't see h265. When I run VK_ICD_FILENAMES=/opt/amdgpu-pro/etc/vulkan/icd.d/amd_icd64.json:/opt/amdgpu-pro/etc/vulkan/icd.d/amd_icd32.json obs-amf-test I get the following output:

Hello doom penguin, currently the -fix packages are stuck to 21.40.2 , but hevc was introduced in 21.50 , on nobara we solved this by using the official libdrm AMD & and the 22.20.3 drivers , the arch maintainers need to replicate our setup, and also heard that with the latest libdrm + kernel , you can use the normal non -fix packages, with out the official AMD lib DRM so try that !

LD_LIBRARY_PATH=/opt/amdgpu/lib/x86_64-linux-gnu:/opt/amdgpu/lib/i386-linux-gnu VK_ICD_FILENAMES=/opt/amdgpu-pro/etc/vulkan/icd.d/amd_icd64.json:/opt/amdgpu-pro/etc/vulkan/icd.d/amd_icd32.json OBS_USE_EGL=1 obs

AMF H.265 still doesn't appear. The AMDGPU-PRO version is 22.20.3. I'm not sure if I'm using libdrm correctly.

EDIT: I am running kernel version 5.19.6-zen1-1-zen, which is the latest on Arch.

Try this

LD_LIBRARY_PATH=/opt/amdgpu/lib/x86_64-linux-gnu:/opt/amdgpu/lib/i386-linux-gnu:"$LD_LIBRARY_PATH" VK_ICD_FILENAMES=/opt/amdgpu-pro/etc/vulkan/icd.d/amd_icd64.json:/opt/amdgpu-pro/etc/vulkan/icd.d/amd_icd32.json OBS_USE_EGL=1 obs

Also make sure you are using the latest normal AMF and Vulkan packages, not the fix ones.

I'm having trouble getting h265 amf to work on Arch. I installed OBS using this AUR package: https://aur.archlinux.org/packages/obs-studio-amf As for the proprietary drivers, I tried amf-amdgpu-pro and amf-amdgpu-pro-fix from the AUR, and my PKGBUILD which can be found here: https://github.com/DoomPenguin9/amdgpu-pro-vulkan-and-amf-only/blob/master/PKGBUILD With amf-amdgpu-pro, neither AMF H265 or H264 would show up in OBS. With amf-amdgpu-pro-fix and my PKBUILD, AMF h264 shows up and works, but I can't see h265. When I run VK_ICD_FILENAMES=/opt/amdgpu-pro/etc/vulkan/icd.d/amd_icd64.json:/opt/amdgpu-pro/etc/vulkan/icd.d/amd_icd32.json obs-amf-test I get the following output:

Also make sure you are using the latest normal AMF and Vulkan packages, not the fix ones.

Still doesn't work. I really don't get what's going wrong here. The normal AMF package from the AUR straight up doesn't work( I don't get h264 or h265 amf) and my personal PKBUILD has everything required in it, and it still only gives me AMF h264. I need libdrm-amdgpu-amdgpu, ibdrm-amdgpu-radeon, and libdrm2-amdgpu, right?

DoomPenguin9 avatar Sep 04 '22 02:09 DoomPenguin9

@DoomPenguin9 Can you give it a try to this repo? It should be the latest AMF / AMDGPU-PRO drivers

https://github.com/HannesMann/archlinux-amdgpu-pro

Just clone the repo and run makepkg -si

alosarjos avatar Sep 04 '22 05:09 alosarjos

You only need to install latest amf and amdgpu-pro vulkan driver, nothing else. For Arch see https://github.com/Ashark/archlinux-amdgpu-pro/pull/78 No libdrm or anything is needed, what made the drivers work on Arch was the amdgpu firmware update.

Also please keep the driver install troubleshooting outside this pull request. Pull request is ready for review, everything works just the same as on Windows (assuming your drivers are installed correctly, and of course without texture encoding).

nowrep avatar Sep 04 '22 05:09 nowrep

Just tested this PR & cloned the following repo and installed it: https://github.com/HannesMann/archlinux-amdgpu-pro

I can safely say that everything is functional when using the right amd-pro driver. This pr makes the AMF encoders viable in the encoder option, if the pro driver is installed properly and has the v22.20.3 or higher. No bugs experienced at all at the current state of this PR.

Tested on Arch Linux & an RX 6700 XT

p0ryae avatar Sep 17 '22 18:09 p0ryae

Forgive my ignorance, but is there any benefit to using this instead of something like this GStreamer based obs-vaapi or the older obs-gstreamer plugins or the even older hevc-vaapi patch? I've used all of those for HEVC encoding on my RX 5700 XT and they've all worked fine.

I get a huge quality difference with way lower bitrate. Specially useful if streaming rather than recording

alosarjos avatar Sep 27 '22 18:09 alosarjos

@DashCruft i use this same spec but the https://github.com/HannesMann/archlinux-amdgpu-pro dont work for me, with the -fix packages from aur i get the h264 to work but not hevc, can you say the packages or what you did for this work for you?

mesmerx avatar Oct 07 '22 06:10 mesmerx

latest amd firmware from 2022-09-13 (on fedora its amd-gpu-firmware, others may be linux-firmware) broke AMF again. Last known working firmware was 2022-08-15. If you dowgrade firmware packages please note you also have to regenerate initramfs and reboot.

On fedora 36: sudo dnf downgrade amd-gpu-firmware sudo dracut -f sudo reboot

Please note this is a firmware issue and -not- an issue with this PR.

GloriousEggroll avatar Oct 07 '22 06:10 GloriousEggroll

@GloriousEggroll oh and I get something strange in my obs, I don't know if it's because of all this strange setup that is needed for the AMF to work. But when I stream to twitch with the AMF in the obs everything seems to be fine but the live never goes on. If I stream to restream the image and sound appears in restream dashboard,but even this when restream to twitch never goes online. I don't know exactly how to debug this. I'll try to make the AMF to work in the last version before return here with more information, but I thing it's good to alert this happens to me

mesmerx avatar Oct 07 '22 09:10 mesmerx

Just to confirm with the firmware 08-15 and the https://github.com/HannesMann/archlinux-amdgpu-pro now my hevc seem to work and the twitch bug are gone, great work ppl :)

arch with 6700xt too

mesmerx avatar Oct 07 '22 09:10 mesmerx

On my new RX 6800 this is literally the only way to get decent encoding quality. obs-vaapi/gstreamer-vaapi or the built in vaapi either require bit rate so high you can only record or the quality is so bad its unusable. My old RX480 is okish with VAAPI but i guess not RDNA2.

Works flawlessly and the quality is the best you can get with an AMDGPU, only better option on linux for AMDGPUs would be when the bargain bin ARC GPUs come rolling out if they have an encoder as a dedicated card.

Currently on Arch you need just the amf-amdgpu-pro and the linux-firmware 20220815 like has been mentioned but otherwise easy to setup.

Big-FG avatar Oct 14 '22 01:10 Big-FG

Thanks to everyone involved to make this work. After many struggles with outdated packages it is now working on my machine as well. To make it easier for everyone finding this thread, I wrote a step-by-step tutorial for Arch:

Workaround to get OBS to record video with HEVC (H.265) or AVC (H.264) hardware encoding using an AMD GPU like the RX 6800 / RX 6900XT on Arch Linux (working state: 2022-10-21):

  1. Install the old version of the linux firmware: linux-firmware-20220815.8413c63-1 (versions above like 2022-09-13 break the HEVC H.265 encoding in OBS)

    1. Downgrade the linux-firmware: sudo pacman -U https://archive.archlinux.org/packages/l/linux-firmware/linux-firmware-20220815.8413c63-1-any.pkg.tar.zst
    2. Downgrade the linux-firmware-whence: sudo pacman -U https://archive.archlinux.org/packages/l/linux-firmware-whence/linux-firmware-whence-20220815.8413c63-1-any.pkg.tar.zst
    3. Confirm both linux-firmware and linux-firmware-whence have been downgraded to 2022-08-15: sudo pacman -Q | grep linux-firmware
    4. Regenerate initramfs: sudo mkinitcpio -p linux
    5. Reboot

  2. Install the OBS package which has the AMF commit merged from the AUR: obs-studio-amf (https://aur.archlinux.org/packages/obs-studio-amf) --> When the pull request (https://github.com/obsproject/obs-studio/pull/7206) is closed, you can use the normal obs-studio version again.

  3. Install the patched version of the proprietary AMDGPU driver of hannesmann:

    1. Clone the repository: git clone https://github.com/hannesmann/archlinux-amdgpu-pro.git
    2. Change into the folder and install it with: sudo makepkg -si

  4. Install the amd vulkan driver switcher from the AUR: amd-vulkan-prefixes (https://aur.archlinux.org/packages/amd-vulkan-prefixes). This package provides vk_pro, vk_radv and vk_amdvlk to start a program with the proprietary AMD driver

  5. Use a tool from the obs-studio-amf package to check, if AMF can be accessed successfully: vk_pro obs-amf-test --> It should say: supports_avc=true supports_hevc=true

  6. Open the terminal and start OBS with the AMD proprietary driver which contains the AMD Media Framework (AMF) which is needed to use hardware enconding H.264 and H.265 in OBS: vk_pro obs

  7. In OBS go to "Settings -> Output -> Advanced (on the top) -> Recording -> Encoder". There select either:

    1. AMD HW H.264
    2. AMD HW H.265 (HEVC)

  8. Start recording. :)

  9. Bonus: To fluently record OpenGL and Vulkan games use obs-vkcapture to enable the "Game Capture" source in OBS:

    1. Install obs-vkcapture from the AUR: https://aur.archlinux.org/obs-vkcapture.git (use the obs-vkcapture package. The obs-vkcapture-git package is outdated)
    2. Install mesa-utils and vulkan-tools providing the testing tools glxgears (OpenGL) and vkcube (Vulkan): sudo pacman -S mesa-utils vulkan-tools
    3. Open OBS with vk_pro obs and add a "Game Capture" source in the Sources section
    4. Open a terminal and execute obs-gamecapture glxgears or obs-gamecapture vkcube to test if OBS recognizes the OpenGL or Vulkan application as an input.

mesmerx avatar Nov 06 '22 05:11 mesmerx

obs-studio-amf is a great build. It has both, AMF and web layers, which is the only two things the average streamer needs.

It would be really nice to have it merged into the main branch, so we don't need to compile every time. It's been months (years?) since this features are working correctly.
