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.)
