I thought to do the corresponding for hevc_vaapi<br>
<br>
However I am struggling to get 10bit 422 output rendered
from Cingg, which so far falls back to 10bit 420 chroma
subsampling<br>

<br>
In a previous thread I proved that ffmpeg hevc_vaapi
encoding has this 10bit-422 capability<br>
3) 10-bit yuv422p10le hevc_vaapi encoding using -vf
'format=y210,hwupload'<br>

<br>
<br>
And yes, there was also issues before
hevc_qsv_10b422.mp4 combinations Pixel format/profile
finally succeeded.<br>
But here are some differences, yet. While hevc_qsv
provided a Pixels drop down menu with pixel formats,<br>
hevc_vaapi just has a single "vaapi" pixel format.<br>
<br>
Any idea why, and what can fulfill the vaapi 10bit 422
encoding here?<br>

Just to clarify: my tests vaapi tests and qsv tests are run on Cingg
with the onevpl patch and internal ffmpeg<br>
