<div dir="ltr"><div class="gmail_default" style="font-size:small">Andrew, when I check into Git the onevpl patch, I would like to checkin Terje's final tested 3 hevc_qsv render formats. Even though there will be relatively few users who not only have the Intel hardware to use these as well as their own build, it seems like a valuable addition.

After finishing the three hevc_qsv presets for _8b420, _10b420 and
_10b422 mp4<br>

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>

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>
