On Linux with Intel graphics (vaapi), deinterlacing does not double FPS (Bob, Linear, Yadif 2x)

In MPV it does work with Intel

[InTheWings]

obviously it can't double fps since interlaced is 2 half frames

Yadif2x should double the framerate.

Does it work better with --avcodec-hw=none?

Code: Select all

vlc --no-hw-dec --deinterlace-mode=yadif2x video.mp4

What?

Yadif2x should double the framerate.

Does it work better with --avcodec-hw=none?

Code: Select all

vlc --no-hw-dec --deinterlace-mode=yadif2x video.mp4

Vlc no longer recognizes --no-hw-dec but does recognize --avcodec-hw=none "vlc: unknown option or missing mandatory argument `--no-hw-dec'"

And yes, without HW VAAPI it does double the FPS as it also does with NVDEC, with VAAPI it gives the error:

MPV does double FPS with VAAPI and NVDEC


(I do not know how to view the deinterlacer used by MPV.)
