Random notes
For easy reference, I've used this command to test:
$ mpv --hwdec=v4l2m2m-copy --vo=tct --quiet --no-audio demo-480.webm
And it displays the video directly in the terminal :)
(Rendering speed depends on terminal size)
I'd never played the video to the end.
I notice I get:
[ 397.410006] qcom-venus cc00000.video-codec: session error: event id:1001 (deadb000), session id:79d7c000
[ 397.410114] qcom-venus-decoder cc00000.video-codec:video-decoder: dec: event session error 1001
How bad is that?
Sometimes, decoding simply fails immediately.
Must quit & restart.
Will have to script a 100 starts and check frequency of failures.
Will test with higher-resolution video.
