Re: FFmpeg qsv_av1

shinigami_28 · ‎09-27-2023

I am having a hard time enabling qsv hw acceleration on latest ffmpeg 6.0, on a headless Ubuntu 22.04 server, 6.5.5 kernel, Intel ARC 770. I successfully compiled oneVPL, oneVPL-gpu and Intel MediaSDK, but I keep getting errors like "No VA display found for device".

Any help please?

Hi,

Thank you for posting in Intel communities.

Can you please provide us more details on below points so that we can assist you better:

1. CPU, Processor and OS details

2. Please confirm that you have the latest versions of all the components (oneVPL, oneVPL-intel-gpu, MediaSDK, etc.)

3. Exact commands which you tried along with screenshot if possible

Regards,

Sreedevi

Sure:

- AMD Ryzen Threadripper 2920X 12-Core Processor

- Acer Predator BiFrost Intel Arc A770 OC 16GB GDDR6

- Ubuntu 20.04.6 LTS

- Kernel 6.5.5-060505-generic

I compiled all the latest master branches as of yesterday of oneVPL, oneVPL-intel-gpu, MediaSDK, libva, libva-utils, GmmLib, Intel(R) Media Driver for VAAPI, and enabled --libvpl configuring latest FFmpeg 6.0...

I couldn't find the strictly required libs for transcoding AV1 on the A770 with FFmpeg, so maybe I installed something that is not strictly required?

I set there env variables:

export LIBVA_DRIVERS_PATH=/usr/local/lib/x86_64-linux-gnu/dri/
export LIBVA_DRIVER_NAME=iHD

Sample cmd:

ffmpeg -hwaccel qsv -qsv_device /dev/dri/renderD128 -c:v h264_qsv -i input.ts -c:v av1_qsv -preset slow -b:v 512k -bufsize 512k -maxrate 1024k -c:a libopus -vbr off -ac 2 -b:a 48k -f Matroska output.mkv

Thank you.

AMD Ryzen Threadripper 2920X 12-Core Processor

Acer Predator BiFrost Intel Arc A770 OC 16GB GDDR6

Kernel 6.5.5-060505-generic

Ubuntu Server 22.04.6

There is a bit of confusion imho about what are the strictly needed libs/driver for enabling AV1 hw transcoding pipeline on Linux...

By the way, I have all the latest versions compiled, and enabled --libvpl during FFmpeg 6.0 configure.

Sample cmd:

ffmpeg -hwaccel qsv -qsv_device /dev/dri/renderD128 -c:v h264_qsv -i input.ts -c:v av1_qsv -preset slow -b:v 512k -bufsize 512k -maxrate 1024k -c:a libopus -vbr off -ac 2 -b:a 48k -f Matroska output.mkv

shinigami_28 · ‎10-03-2023

Any news on this topic?

Even a simple cmd like this one:

ffmpeg -hwaccel qsv -qsv_device /dev/dri/card0 -i input.mp4 -preset slow -b:v 512k -bufsize 512k -maxrate 1024k -c:a libopus -vbr off -ac 2 -b:a 48k output.mp4

results in:

[AVHWDeviceContext @ 0x560204e90080] Failed to initialise VAAPI connection: -1 (unknown libva error).

Device creation failed: -5.

Failed to set value '/dev/dri/card0' for option 'qsv_device': Input/output error

ffmpeg -encoders | grep qsv

QSV encoders and decoders are both listed by FFmpeg.

Any help please?

Hi,

We are checking on this internally and will get back to you with an update shortly.

Meanwhile, could you please share the below details:

1. VAinfo output details

2. Is the card inserted in qsv_device supported by FFmpeg?

Regards,

I also tried with a monitor attached, or with export DISPLAY=:0.0, same output.

I tried both devices listed in /dev/dri/, which are card0 and renderD128.

A770 is the only GPU currently installed in the server.

Hi,

It seems like you were not able to enable media stack properly for VPL. So, can you please follow the below installation steps:

https://dgpu-docs.intel.com/driver/installation.html#ubuntu-install-steps

Also, please check if FFmpeg-VPL(FFmpeg-qsv-av1) is enabled or not.

Regards,

Sreedevi

shinigami_28 · ‎10-05-2023

Managed to install everything.

vainfo output:

Is there something wrong with latest libva?

SreedeviK_Intel · ‎10-31-2023

Hi,

Thank you for sharing all the details that we had requested.

Though you have mentioned that you have installed libva-utils, we assume that the libva-utils might have an issue. Could you please follow all the steps given in this readme file :

https://github.com/intel/libva-utils

Please let us know if the issue still persists or not.

Regards,

Sreedevi

shinigami_28 · ‎10-31-2023

I think you are right, libva-utils returns an error both using meson/ninja and autogen.

Hi,

Thank you for sharing the details.

We observed that you have two different versions of Intel media stack.

libva info: VA-API version 1.21.0

libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so

libva info: Found init function __vaDriverInit_1_21

and

libva info: VA-API version 1.21.0

libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so

libva info: Found init function __vaDriverInit_1_14

In the latest one, iHD was built against VA-API 1.14, so the init function is __vaDriverInit_1_14. So, can you please try a clean-up to the system since the init function should be __vaDriverInit_1_21 if it was built against VA-API 1.21.0

For the error, ffmpeg: symbol lookup error: /lib/x86_64-linux-gnu/libva-x11.so.2: undefined symbol: va_fool_postp

This can also be caused because of two different media stack. Usually, libva-x11.so.2 is installed under /usr/lib/x86_64-linux-gnu/ in Ubuntu, not /lib/x86_64-linux-gnu/

Could you please try to clean up your system to make sure that you don't have conflicting versions and let us know if the issue still persists?

Regards,

Sreedevi

shinigami_28 · ‎11-02-2023

Thanks.

So, I tried again on a clean system, both using mediasdk and oneVPL-intel-gpu frontends (which one is the best??), without luck.

sudo vainfo --display drm --device /dev/dri/renderD128

Trying display: drm
libva info: VA-API version 1.21.0

vaInitialize failed with error code -1 (unknown libva error),exit

ffmpeg: symbol lookup error: /lib/x86_64-linux-gnu/libva-x11.so.2: undefined symbol: va_fool_postp

As you said, libva-x11.so.2 path seems to be different.

Any hints?

Can you please try uninstalling and reinstalling FFMpeg and libva with the below commands once again to see if the issue disappears?

sudo apt-get --purge remove libav-tools
sudo apt-get --purge autoremove
sudo apt remove ffmpeg

For reinstalling, try as below:

sudo apt-get update -qq && sudo apt-get -y install \
 autoconf \
 automake \
 build-essential \
 cmake \

 libxcb-shm0-dev \
 libxcb-xfixes0-dev \
 meson \
 ninja-build \
 pkg-config \

 zlib1g-dev

sudo apt-get upgrade
sudo apt-get install ffmpeg

sudo apt-get install git cmake pkg-config meson libdrm-dev automake libtool
git clone https://github.com/intel/libva.git
cd libva
./autogen.sh --prefix=/usr --libdir=/usr/lib/x86_64-linux-gnu

make
sudo make install

sudo apt install autoconf libtool libdrm-dev xorg xorg-dev openbox libx11-dev libgl1-mesa-glx

git clone https://github.com/intel/media-driver.git
mkdir build_media
cd build_media
cmake ../media-driver
make -j"$(nproc)"
sudo make install

Check vainfo command

Can you please try these and let us know if the issue still persists.

Regards,

but if I try to convert using FFmpeg av1_qsv I still get:

Hi,

Thank you for sharing the information with us.

We were able to run the command provided by you. Observing your error, it seems like something is wrong with your environment.

QSV is based on VA-API under Linux, QSV won't work as expected if VA-API is not supported. Can you please provide the output of the command below:

$ ffmpeg -hwaccels | grep vaapi

If vaapi isn't supported in your FFmpeg, you may reinstall your libva or add libva to the search path of pkg-config, then check whether libva (VA-API) is available.

$ pkg-config --modversion libva

Once libva (VA-API) is available in your environment, you may rebuild your FFmpeg.

Kindly let us know if the issue still persists.

Regards,

Sreedevi
