Hi Leo, Christian and Julien,

I tested the patch with Vaapi Encoding and Transcoding, it seems
working fine. We are using "VAAPI_DISABLE_INTERLACE" env, so
interlaced is always disabled.

Though I notice it will break screen recording scripts for existing
users who previously didn't need the env set but will after this.

Totally untested/thought through, but maybe the env should default to

Agree, can you come up a patch for that?

OK, but maybe I should test a bit first to see if anything regresses.

It seems true is needed for most gstreamer encodes now, so I guess it will need to be set on.

As for regressions I haven't tried ffmpeg encode as it's currently not working.

One I found with mpv which I guess is obvious =

mpv --hwdec=vaapi --vo=vaapi foo

works with or without the env, but if foo is interlaced you can't use the vavpp de-interlacer with the env set.
