 |

Hi everyone,
I'm trying to encode a video using vaapi but I get the following error:
| Code: | adel@t14 ~ $ ffmpeg -y -hwaccel vaapi -f x11grab -framerate 25 -video_size 1920x1200 -i :0.0 -vcodec h264 /media/ssd/recordings/output.mp4

Device creation failed: -5.

any idea what I'm missing here? |

When media-libs/libva is installed, part of the message says, roughly:
| Code: | To support "Older Intel GPU support up to Gen8", install media-libs/libva-intel-driver
To support "Newer Intel GPU support from Gen9+", install media-libs/libva-intel-media-driver

| fwiw may want to try -c:v h264_vaapi video codec rather than -hwaccel so it doesn't trip on the rawvideo thing, albeit if it doesn't init at all that likely won't help |

To me the command looks like you're trying to do vaapi hardware accelerated raw video decoding, not encoding.
Try Ionen's suggestion. And if neccessary add -hwaccel vaapi after you have specified the input (after -i :0.0).

thanks grknight, I have installed libva-intel-media-driver and vainfo is working now
as for hardware acceleration of the encoding I modified the command as follows:
| Code: | | adel@t14 ~ $ ffmpeg -y -f x11grab -framerate 25 -video_size 1920x1200 -i :0.0 -c:v h264_vaapi /media/ssd/recordings/output.mp4 |
but I encountered:
| Code: | [x11grab @ 0x565106841940] Stream #0: not enough frames to estimate rate; consider increasing probesize

Try adding
-vaapi_device /dev/dri/renderD128
before input and
-vf 'hwupload,scale_vaapi=format=nv12'
after input as shown in the example here: https://trac.ffmpeg.org/wiki/Hardware/VAAPI#ScreenCapture
| Code: | | ffmpeg -vaapi_device /dev/dri/renderD128 -f x11grab -video_size 1920x1080 -i :0 -vf 'hwupload,scale_vaapi=format=nv12' -c:v h264_vaapi -qp 24 output.mp4 |

| thanks that works like a charm, what about HEVC or h.265? I cannot find the vaapi video codec for that |

There should be -c:v hevc_vaapi, and afaik it should be supported with your hardware (albeit don't use vaapi myself, on nvidia, so not entirely sure) |

doesn't seem to work:

Is it missing from FFmpeg perhaps?
Try 'ffmpeg -encoders | grep vaapi'.
Example output:
| Code: | V....D h264_vaapi H.264/AVC (VAAPI) (codec h264)
V....D hevc_vaapi H.265/HEVC (VAAPI) (codec hevc)
V....D mjpeg_vaapi MJPEG (VAAPI) (codec mjpeg)
V....D mpeg2_vaapi MPEG-2 (VAAPI) (codec mpeg2video)
V....D vp8_vaapi VP8 (VAAPI) (codec vp8)
V....D vp9_vaapi VP9 (VAAPI) (codec vp9) |

Maybe the format=nv12 or so is not valid for it? Sounds to me hevc_vaapi itself is reporting an error rather than not being found.
The page chiitoo linked gives some hevc examples too, may want to check these. |

Oh, yeah, probably...
I did try
| Code: | | ffmpeg -vaapi_device /dev/dri/renderD128 -f x11grab -video_size 1920x1080 -i :0 -vf 'hwupload,scale_vaapi=format=nv12' -c:v hevc_vaapi -qp 24 output.mp4 |
which works here with an AMD RX 5700 XT / amdgpu, but yeah, maybe the format is not right for everything.
One of the examples mentions "recent hardware required - Kaby Lake or later Intel"... not sure what that means here, if anything. :]

the encoder is present in ffmpeg:
| Code: | V....D h264_vaapi H.264/AVC (VAAPI) (codec h264)
V....D hevc_vaapi H.265/HEVC (VAAPI) (codec hevc)
V....D mjpeg_vaapi MJPEG (VAAPI) (codec mjpeg)
V....D mpeg2_vaapi MPEG-2 (VAAPI) (codec mpeg2video)
V....D vp8_vaapi VP8 (VAAPI) (codec vp8)
V....D vp9_vaapi VP9 (VAAPI) (codec vp9) |
I'll look at the exmaples and try them out |
