I've never gotten QSV to work, but I use Linux. You can also try --param use-hw-accel
instead
I'm trying to run uv with qsv encoder and decoder, but it always end task without any failure, or warning.
./uv -t testcard -c libavcodec:encoder=h264_qsv:subsampling=420:bitrate=10M -d gl --param force-lavd-decoder=h264_qsv
when I use encoder libx264 / libx265 and decoder h264_qsv / h265_qsv it works so great.
So to simplify that, the QuickSync encoder doesn't work, so minimal not-working example is:
uv -t testcard -c libavcodec:encoder=h264_qsv
right? I've tried with i7-8750H, which has Intel UHD 630 (compared to i5-8350U's 620) and it worked for me (both encoder and decoder). But I've tested with Win 10, I may try to retry with W11 if I get it there.
Okay, my fault. I've realized where the problem perhaps lies. There was a small error that has been already fixed by d3dbe09. It is already include in our continous development builds. That's perhaps why it worked for me flawlessly because I've tested with the current version.
The fix will be released in next bugfix release 1.8.1.
(Just FYI, I've also retested the continuous build in W11 and it works but it is quite clear from the above.)
Hi Martin, thank u so much, continous build works greatfully with qsv encoder an decoder too. There is one question is a continous dev build safe for show?

We run continuous Linux build in production.
There is one question is a continuous dev build safe for show?
I'd say so. The continuous channel is not supposed to be unstable. On the other hand, it is true that new bugs may occur (in contrary to the stable channel). But vast majority of them doesn't have any impact on running stability and are rather dispatched during initialization (just like the bug reported by you).
Hallo and Happy New Year,
I'm trying to run uv with qsv encoder and decoder, but it always end task without any failure, or warning.
./uv -t testcard -c libavcodec:encoder=h264_qsv:subsampling=420:bitrate=10M -d gl --param force-lavd-decoder=h264_qsv
when I use encoder libx264 / libx265 and decoder h264_qsv / h265_qsv it works so great.
There is a terminal after run with qsv encoder
and here is libavcodec help, qsv encoders are listed:
