Again, your problem seems to be -vf scale,lavc. Have you tried without

There is nothing wrong with that, in your day-to-day use that is. But
it can make it unnecessarily more difficult to understand what is going
on. And there is always always copy and paste and the shell history to
make things easier.

I get that.

Which error message did you not expect? An error or a warning is what I
would expect, if I were trying to use an unsupported codec.

"The selected video_out device is incompatible with this codec." is the
exact error message I get when I use any ff*vdpau in combination with
-vf filters. Those are software filters which cannot work, since the
video gets decoded by your graphics card and the undecoded frames go
directly to your screen and not again through the CPU, where those -vf
filters are executed.
So it is most certainly not "-vc ffhevcvdpau," that is causing an
error, because the trailing comma allows a fallback to other codecs.

If anything, that error message is misleading, because it is not the
video _codec_ that is incompatible with the output device but the video

The part about ffhevcvdpau was just meant as a BTW, nothing more. And
you weren't exactly forthcoming with the information you just provided
above, so how would I know that to be the reason for having it in the
