Error initializing an internal mfx session unsupported 3

I have found that ffmpeg qsv encoder command line ffmpeg -i input.mp4 -b:v 10000k -vcodec h264_qsv -preset fast output.mp4 may throw: "Error initializing an internal MFX session: unsupported (-3)" message on "windows" box configuration. (first noticed on ffmpeg 4.0.2 but recent master build also suffers from with problem). OBS-Studio+QSV works without problem on same machine.

I have found that ffmpeg qsv encoder command line
ffmpeg -i input.mp4 -b:v 10000k -vcodec h264_qsv -preset fast output.mp4
may throw: «Error initializing an internal MFX session: unsupported (-3)» message on «windows» box configuration.
(first noticed on ffmpeg 4.0.2 but recent master build also suffers from with problem).
OBS-Studio+QSV works without problem on same machine.

By using several test machines(4 different windows boxes) i narrowed the circle of suspects and here is repro:

  • windows 10 x64 1809
  • internal intel graphics enabled in bios (windows driver intstalled) but monitor is not connected
  • discrete graphics card enabled and multiple monitors (>=2) connected

OBS works, ffmpeg fails
If only one monitor is connected to discrete card then ffmpeg starting to work.

So i digged in source comparision cause OBS-studio and ffmpeg depending on same libmfx (but different version).

ffmpeg uses this piece of code:
ffmpeg/libavcodec/qsv.c

mfxIMPL impl = MFX_IMPL_AUTO_ANY;
mfxVersion ver = { { QSV_VERSION_MINOR, QSV_VERSION_MAJOR } };
….
ret = MFXInit(impl, &ver, session);

obs:
​https://github.com/obsproject/obs-studio/blob/a4f602b15afcd54e588e76437c639c38278841f6/plugins/obs-qsv11/obs-qsv11-plugin-main.c#L70

mfxIMPL impl = MFX_IMPL_HARDWARE_ANY | MFX_IMPL_VIA_D3D11;
mfxVersion ver = {{0 , 1}};
….
sts = MFXInit(impl, &ver, &session);

if (sts == MFX_ERR_NONE) {
….
} else {

impl = MFX_IMPL_HARDWARE_ANY | MFX_IMPL_VIA_D3D9;
sts = MFXInit(impl, &ver, &session);
if (sts == MFX_ERR_NONE) {

….

OBS force mfx to use HW implementation with «manual» fallback from dx11 to dx9.
I have changed ffmpeg to use OBS technique and it starts to initialize even multiple monitors were connected.

Conclusion:
For some completely unknown reason MFXInit(MFX_IMPL_AUTO_ANY …) call fails with multi monitor config.
It might be releated to some libmfx bug, but OBS-Studio implementation did not triggers it.
So it would be nice if FFmpeg adopts this technique (by adding option to force HW DX11 or/and DX9 QSV implementation)

Im using ffmpeg build for Windows from gyan.dev: release ffmpeg-5.0-full-build with hardware-support.
I need to capture a video from a USB video device, compress it and write it to a file.
I am using the following command line:

ffmpeg -f dshow -i video="USB Video" -c:v h264_qsv m:out21.mp4

And I get error:
Error initializing an internal MFX session: unsupported (-3)

This error occurs on different systems:

Desktop, Windows 7, Intel Core i7-4770

Panel PC, Windows 10 Enterprise, Intel Celeron N3350E

This issue occurs on linux only in ffmpeg qsv decode, and could be reproducde with any clips(H264/H265).
However, it works on windows.

Since there seems to be no difference in FFmpeg level, it may be relevant with the difference between windows and linux.

cmdline:
ffmpeg -v verbose -init_hw_device qsv=hw -filter_hw_device hw -c:v hevc_qsv -i Tears_400_x265.mp4 -y -vframes 2 out.yuv

Error msg:
[hevc_qsv @ 0x1471fc0] Initialized an internal MFX session using hardware accelerated implementation
[hevc_qsv @ 0x1471fc0] Current input bitstream is not supported by QSV decoder.
[hevc_qsv @ 0x1471fc0] Error initializing the MFX video decoder: unsupported (-3)
Error while decoding stream #0:0: Function not implemented

Analysis:
This error may be relevant with FactoryCORE::CreateCORE and VAAPIVideoCORE::SetHandle.
On Linux, the created CORE is used in MFXVideoDECODE_Init/MFX_Utility::CheckVideoParam without calling SetHandle.

However since windows works well, I’m wondering how MSDK for windows cope with this in MFXInit or MFXVideoDecode_Init?

For example, when allocating video core, there is difference between windows and linux.

When I use hevec_qsv encoding, ffmpeg always fails as follows.
And also multimedia/handbrake doesn't show QSV encodings on the Video encoder menu.

```
$ ffmpeg -i /zpool/video/test.avi -vcodec hevc_qsv hevec_qsv_test.mp4

If I downgrade intel-media-sdk to 21.3.0, it works as I expected.

It seems that hardware detection method has been changed since 21.3.1.
Setting environment variable as `INTEL_MEDIA_RUNTIME=MSDK` works for me as a workaround.

Re: Intel Iris Xe и mx450 выдает ошибку

ну, могу только посоветовать заменить mpv.exe на самый последний билд, и если то же самое то только писать письма в интел

Re: Intel Iris Xe и mx450 выдает ошибку

нашел решение: загуглил эту ошибку   «Error initializing an internal MFX session: unsupported (-3)» На реддит , кто то связывал ее с настройками нескольких мониторов. Отключил скринпад и все заработало.

1. What is not working as documented?

My video playback was extremely slow with non-HEVC videos, so I looked at the logs and saw a bunch of:

h264_qsv: failed transcoding

messages. I turned on debug logging and kept seeing

Error initializing an internal MFX session: unsupported (-3)

Hardware transcoding was not working at all. I tried a lot of things that didn’t work, but finally ran ls -l /dev/dri inside the container and saw that the GID for the renderd128 device was a bare number instead of the render group’s name. This seems to be a problem.

So on the host, I ran chmod 777 /dev/dri/renderD128 and restarted the docker container. This time, no more errors and I could see in intel_gpu_top that the GPU was working!

This, however, is not sustainable because it resets on host reboot, and other containers work with hardware acceleration without doing host permission changes (like Plex).

2. How can we reproduce it?

Steps to reproduce the behavior:

  1. Use :preview docker image on an Intel machine that can do QSV and has its /dev/dri/renderd128 owned by the render group that doesn’t have the GID 115 that PhotoPrism seems to hardcode in create-users.sh.
  2. Enable FFMPEG’s intel encoder in the docker options.
  3. Try to stream some video files that required transcoding.
  4. Check the log to see that it fails to transcode using hardware encoder.

3. What behavior do you expect?

The docker container should handle GIDs for the render group that aren’t 115. I think.

4. What could be the cause of your problem?

The create-users.sh file hardcodes the render group’s PID as 115 so there’s a mismatch between the container and the host, stopping the container from accessing the /dev/dri/renderd128 device. The logs don’t clearly indicate this as the cause so it requires lots of debugging.

Someone had a similar issue on the Plex Linuxserver container (linuxserver/docker-plex#207), and it was solved by Linuxserver changing their user/group addition logic to be more dynamic, it seems (https://github.com/linuxserver/docker-plex/blob/master/root/etc/cont-init.d/50-gid-video).

Giving everything in /dev/dri 777 permissions «fixes» the problem, pointing to a permissions issue.

5. Can you provide us with example files for testing, error logs, or screenshots?

See above for the ffmpeg errors.

6. Which software versions do you use?

(a) PhotoPrism Architecture & Build Number: AMD64, 220919-cc8bab446

(b) Database Type & Version: MariaDB, latest

(c) Operating System Types & Versions: Linux

(d) Browser Types & Versions: Safari on Mac

(e) Ad Blockers, Browser Plugins, and/or Firewall Software? No

7. On what kind of device is PhotoPrism installed?

(a) Device / Processor Type: Intel Core i7-7700K

(b) Physical Memory & Swap Space in GB: 16GB + 8GB swap

(c) Storage Type: SSD + HDD

(d) Anything else that might be helpful to know?

I’m also using vGPU for a Windows VM on the same machine. Plex works with hw acceleration in another container.

8. Do you use a Reverse Proxy, Firewall, VPN, or CDN?

No

On Intel 12th gen CPUs (Alder Lake), ffmpeg requires package libmfx-gen1.2 to use QSV hardware decoding/encoding, but it’s not marked as a dependency and therefore not installed with ffmpeg.

As stated on https://github.com/Intel-Media-SDK/MediaSDK#media-sdk-support-matrix, ADL-S, ADL-P and future Intel CPUs are not supported by libmfxhw64.so.1. When h264_qsv is used as a decoder or encoder, without libmfx-gen1.2 installed, ffmpeg exits with error:
Error initializing an internal MFX session: unsupported (-3)

This is because the libmfx.so.1 dispatcher wants to dispatch to libmfx-gen.so.1.2 for the Intel Quick Sync Video support, but can’t due to the missing shared library.

When libmfx-gen1.2 is installed, the dispatcher succeeds and the QSV usage occurs.

It seems to me that libmfx-gen1.2 should be marked as a dependency (possibly as a dependency of libavutil56, of which ffmpeg depends) to ensure QSV hardware can be used on Alder Lake architectures, and beyond, without users figuring this out themselves.
