These test cases can work on intel-vaapi-driver One CMD line shown as below: ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -y -s:v 1920x1080 -i ./1080p_blue_sky.yuv -vf format=nv12,hwupload -c:v vp8_vaapi -loop_filter_level 16 -loop_filter_sharpness 12 -g 30 -global_quality 40 1080p_1920x1080_i420_looplevel16_loopsharpness12_bf1_gop30_gquality40_fps30.ivf

which platform? in my SKL, use vainfo can't find the VP8 ENC entrypoint, so I think VP8 ENC fail in SKL is a expectable action if iHD didn't support VP8 ENC.

@FocusLuo hi focus, could you share your platform information

[FocusLuo]

@XinfengZhang Carl, I used the CFL/KBL/GLK/SKL/APL platforms

[XinfengZhang]

@focus, VP8 encode support is from CNL

[XinfengZhang]

close it , for VP8 encode support is from CNL.
