VAAPI: Transcoding MJPEG to VP9 fails on GeminiLake

[radek.hvizdos]

Encoding VP9 via VAAPI works, but not when trying to use VAAPI to also HWAccel MJPEG decode. The error is: Failed to end picture encode issue: 6 (invalid VASurfaceID).

Tested combinations:

decoder encoder    result
HWAccel vp9_vaapi  FAIL
SW      vp9_vaapi  OK
HWAccel vp8_vaapi  OK
SW      vp8_vaapi  OK
HWAccel libvpx-vp9 OK

I am not sure if this is a bug in ffmpeg, vaapi or the gpu driver.

[jkqxz]

It's decoding the JPEG to vaapi/yuv420p, and that gets passed directly to the vp9_vaapi encoder. The encoder agrees it supports that format, but then seems to fail on encode saying the surface is invalid.

Despite what the capabilties say, maybe it doesn't support yuv420p input - try adding -vf scale_vaapi=format=nv12?

Adding the specified options has 'fixed' the issue, I can now run the transcode fully in hardware. The speedup is almost 3x :)

The following was shown in ffmpeg output, the different surface was accepted by the encoder:

Can we fix the encoder to either support yuv420p, or stop it from advertising the capability to do so? How come this works for vp8_vaapi?

Thank you!

Any updates?
