You can use vainfo to find the Intel gpu device correctly: "vainfo --display drm --device /dev/dri/renderD12X" Then specify device in ffmpeg cmdline with "-qsv_device /dev/dri/renderD12X" BTW, for legacy platforms, suggest to use libvpl with Media SDK for the runtime implementation: https://github.com/intel/libvpl https://github.com/Intel-Media-SDK/MediaSDK Thanks Fei > > My tested ffmpeg code lines and system information below. > > 1) Tested first this simple ffmpeg decode bencmark code line from > https://trac.ffmpeg.org/wiki/Hardware/QuickSync#Decode-only > This works fine on single GPU Caby Lake/UHD 620 and on Alder Lake/Arc > A750, but on Skylake with dual iGPU HD 530 and a Nvidia GeForce GTX > 960 > card, these errors are reported: > > ffmpeg -hide_banner -hwaccel qsv -hwaccel_output_format qsv -i > h264_8bit_yuv420p.mp4 -f null - > .... > [AVHWDeviceContext @ 0x55bed1a7c500] Error creating a MFX > session: -9. > Device creation failed: -1313558101. > [vist#0:0/h264 @ 0x55bed1a656c0] [dec:h264_qsv @ 0x55bed1a64300] > No > device available for decoder: device type qsv needed for codec > h264_qsv. > [vist#0:0/h264 @ 0x55bed1a656c0] [dec:h264_qsv @ 0x55bed1a64300] > Hardware device setup failed for decoder: Unknown error occurred > [vost#0:0/wrapped_avframe @ 0x55bed1a63740] Error initializing a > simple filtergraph > Error opening output file -. > Error opening output files: Unknown error occurred > bench: maxrss=59076KiB > > > > 2) Additional tests where I experimented to apply suggestions from > https://trac.ffmpeg.org/wiki/Hardware/QuickSync#Transcode > > -qsv_device is an qsv customized option can be used to specify > a > hardware device and avoid the default device initialization > failure > when multiple devices usable (eg: an Intel integrated GPU and an > AMD/Nvidia discrete graphics card). > > > ffmpeg -hide_banner -hwaccel qsv -qsv_device /dev/dri/renderD128 > -i > h264_8bit_yuv420p.mp4 -f null - > DRM_IOCTL_VERSION, unsupported drm device by media driver: nvid > DRM_IOCTL_VERSION, unsupported drm device by media driver: nvid > [AVHWDeviceContext @ 0x56330da80dc0] libva: > /usr/lib64/dri/iHD_drv_video.so init failed > [AVHWDeviceContext @ 0x56330da80dc0] Failed to initialise VAAPI > connection: 18 (invalid parameter). > Device creation failed: -5. > Failed to set value '/dev/dri/renderD128' for option > 'qsv_device': > Input/output error > Error parsing global options: Input/output error > > > ffmpeg -hide_banner -hwaccel qsv -qsv_device /dev/dri/renderD129 > -i > h264_8bit_yuv420p.mp4 -f null - > [AVHWDeviceContext @ 0x55deafcbcec0] Error creating a MFX > session: -9. > Device creation failed: -1313558101. > Failed to set value '/dev/dri/renderD129' for option > 'qsv_device': > Unknown error occurred > Error parsing global options: Unknown error occurred > > > ffmpeg -hide_banner -init_hw_device qsv=hw -filter_hw_device hw > -hwaccel_output_format qsv -hwaccel qsv -qsv_device > /dev/dri/renderD128 -i h264_8bit_yuv420p.mp4 -f null - > [AVHWDeviceContext @ 0x563f568e7e00] Error creating a MFX > session: -9. > Device creation failed: -1313558101. > Failed to set value 'qsv=hw' for option 'init_hw_device': Unknown > error occurred > Error parsing global options: Unknown error occurred > > > 3) and also tried to apply the answer from > https://stackoverflow.com/questions/44747381/i-cant-use-hw-encoder-of-qsv-by-ffmpeg#47145215 > > <https://stackoverflow.com/posts/47145215/timeline> > > It looks like ffmpeg is looking in its list of devices for a qsv > type device and not finding it.
