Navi 10 (Rx5600xt) FFMPEG OpenCL/Vaapi Pop-os 20.04 LTS not functioning correctly/ Halting on openCL initialize

Camofelix · September 20, 2020, 7:05pm

Hey Everyone!

A bit of a weird one on my hands. I’m in the process of getting a special build of FFmpeg going to accelerate HDR->SDR tone-mapping of HEVC content. I can do it all in software as of now, but (to the surprise of nobody) it isn’t exactly realtime performance, even with 24 threads.

As such, I’m trying to implement the same sort of thing using an rx 5600xt as an accelerator card. both VA-API and OpenCL support versions of the transforms I’m looking to use, so unless there’s a massive performance difference, I’m not overly bothered about which one to use.

I’ve listed a lot of details/steps I’ve already tried below, am open to any and all suggestions!

As of now that would mean 3 options for HWacceleration configuration:

AMD’s AMF decoder/encoder. Unfortunately little to no linux support whatsoever, tho I am following the github issues to see if/when that changes.
VA-API. Well supported and reasonably well documented, this is my first choice if I can get it working.
OpenCL. VERY well documented but not included in the open source amdgpu driver, you can perform a “hack” using the amdgpu-pro package topotentially install the OpenCL libraries with support for Navi-10

When I run vainfo I get: error: can't connect to X server! error: failed to initialize display

Where it get’s very weird is that, when running journalctl -b | grep -iE 'vdpau | dri driver' it returns

Sep 19 19:19:49 felix-server /usr/lib/gdm3/gdm-x-session[1764]: (II) AMDGPU(0): [DRI2] DRI driver : radeonsi

Sep 19 19:19:49 felix-server /usr/lib/gdm3/gdm-x-session[1764]: (II) AMDGPU(0): [DRI2] VDPAU driver: radeonsi

Indicating what I think is that the radeon driver has flagged that the system is capable of VA-API support.

When Trying to run clinfo it initially returned:

clinfo
Number of platforms 0

Trying to trouble shoot I found this guide on the blender forums for enabling OpenCL by only using a portion of the AMDGPUPro drivers- with documented success of openCL working on popos 20.04 LTS, tho in their case it was with an RX580.

After having used that “Hack” and then running clinfo, I received:

Unfortunately it now seems that the OpenCL packages are installed and recognized, but are not grabbing the GPU as an eligible device.

in terms of platform, here’s the output of uname -a followed by lshw -short inside of the summery tab

Two things.
Are you running xorg or wayland as your display server?
With Navi, you need to be on the 5.6/5.7 kernel at the very least to use features of this card natively. If you run the AMDGPU Pro driver, you may be able to get this to work, but that method is not recommended. It seems that the hack that you used puts you running a hybrid stack.

VAA and AMF should take care of what you need me thinks.

TLDR; with all the video metadata removed vaapi no longer complains, but ffmpeg can no longer parse the file. So I think that if we can figure out what exact metadata needs to be changed, that will crack this puzzle! Any idea which metadata fields would need to be changed/removed for a file to not be considered HDR?

Currently running x11 (confirmed via loginctl show-session $(awk '/tty/ {print $1}' <(loginctl)) -p Type | awk -F= '{print $2}' )

I managed to get open CL installed using the newest version of the standard driver- thankfully without the hybrid graphics stack. (output of clinfo at the bottom.)

VAAPI is also detected now, but unfortunately I’ve hit the next snag.

When I try and use any opencl filter ffmpeg just locks up completely without doing anything (even if I only do a HWupload/hwdownload without invoking any features).

ffmpeg -loglevel verbose -init_hw_device opencl=gpu -threads 12 -filter_hw_device gpu -i input.mp4 -vf "format=p010,hwupload,hwdownload,format=p010" output.mp4

Returns :
[AVHWDeviceContext @ 0x555fb18689c0] 0.0: AMD Accelerated Parallel Processing / gfx1010
Then just’s sits there until I kill the process/ hit ctrl-c. I’ve had it run for over an hour to see if it’s just taking a really long time to initialize, but with only a 30 second file that doesn’t seem reasonable

Trying to get the tonemping working using VAAPI instead. Sample of the command is:
ffmpeg -loglevel verbose -init_hw_device vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format yuv420p10 -i input.mp4 -vf "zscale=t=linear,format=gbrpf32le,zscale=p=bt709,format=p010,hwupload,tonemap_vaapi=format=p010:t=bt2020-10,hwdownload,format=p010" output.mp4

Note: the reason for using the zscale conversions has to do with attemting to “trick” VAAPI into not realizing it’s working on HDR material. Not sure if it’s a flag that get’s set up an initialazation off the FFMPEG filters. To try another way of getting around the HDR NOT SUPPORTED issue, I added
-map_metadata -1

but unfortunately the HDR not supported flag was still triggered.

Returns:

Conversion failed!

So Trying to trick it, I considered ffmpeg -i initial.mp4 -map_metadata -1 -c copy input.mp4 and then piping that into the VAAPI command. thankfully this process is incredibly quick, operating ~ 93.2x speed.

so, the total command would then be: ffmpeg -loglevel verbose -i initial.mp4 -map_metadata -1 -c copy input.mp4 | rm output.mp4 | ffmpeg -loglevel verbose -init_hw_device vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i input.mp4 -vf "hwupload,tonemap_vaapi=format=p010:t=bt2020-10,hwdownload,format=p010" output.mp4 | rm input.mp4

Now what’s interesting now is that VAAPI is not complaining anymore. with all the video metadata removed, but ffmpeg can no longer parse the file. So I think that if we can figure out what exact metadata needs to be changed, that will crack this puzzle!

Metada removal piped into vaapi tonemap output

ffmpeg -hide_banner -loglevel verbose -i initial.mp4 -map_metadata:s:v  -1 -c copy input.mp4 |ffmpeg -hide_banner -loglevel verbose -init_hw_device vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i input.mp4 -vf "hwupload,tonemap_vaapi=format=p010:t=bt2020-10,hwdownload,format=p010" output.mp4 | rm input.mp4
