bz2 compressed vid showing the issue -

To be clear this is just the test rez vid I used so you can
possibly recreate the issue your self.

Hmm, interesting, with bicubic, hqscaling=1 this vid behaves
differently with mplayer compared to mpv, the latter looks like
it's scaling a bit, maybe there's an off by one somewhere in mpv

I don't know if it's the cause, but looking for differences between
mplayer and mpv it seems that mpv sets video mixer height so it's
divisible by 32 but mplayer doesn't. For this 720p sample it uses 736
and mplayer uses 720.

vdp_video_mixer_create(1, 1, {11}, 3, {0, 1, 2}, {1280, 736, 0}, -)

for output surfaces and render calls it uses 720.

So does the bicubic code see/use this 736 somewhere?

To answer my own question - it does.

Putting a printf in vl_bicubic.c create_frag_shader video_height = 736
