Replying to [comment:5 MasterQuestionable]:
> ͏ Is it AV1 specific?
Yes I think so. Didn't encounter the error with AVC
> ͏ And per previous description hardware decoding shouldn't matter?
Hardware decoding doesn't matter, except for libplacebo that works. Before
v7 every file worked. I think I also had a working AV1 file, but most
won't work. (Attached file won't work)
>
> ͏ What happens?
> ͏ `ffmpeg -v debug -hide_banner -nostdin -nostats -f lavfi -i
"testsrc" -vframes 1 -vf "scale=1x1" -f null -`
This won't work, because it tries to sue the input as filter:
{{{
ffmpeg -v debug -hide_banner -nostdin -nostats -f lavfi -i "in.mkv"
-vframes 1 -vf "scale=1x1" -f null -
}}}
[AVFilterGraph @ 0x583487e06ec0] No such filter: 'in.mkv'
[AVFilterGraph @ 0x583487e06ec0] Error processing filtergraph: Filter not
found
I put the -f lavfi to the filters
{{{
