I see that memory is reducing before this although I still have spare - is this
the same issue you explained on users WRT leaking on decode?
Yeah, I also run out of ... something ... at around 7200 frames. It's not fds
or memory. I don't think it's the buffer problem (which, incidentally, should
finally be fixable sensibly in libva2 soon), because that ended up manifesting
as leaking memory. It's also not a problem for Intel (I've already been
running that for a long time to test). Maybe some other sort of handle on the
Mesa side? I'll investigate further tomorrow.
Leo has fixed the leak.
Yep, checked with the updated Mesa postproc patches + libva2 fixes and it all
looks good now. (And colours are even correct, yay! I still need to look into
why the default comes out wrong with the postproc bits for that on Intel...)
One thing that comes out in testing the patches WRT postproc is that for
deinterlace 1080i25 -> 1080p50 there is an issue with the surface size
being 1088.
This means the result gets scaled to 1088. It is possible to put scale
after to get 1080, but this seems sub-optimal, costs about 8% perf and
hypothetical quality issue (not that I could see it).
Apparently vaapi_scale does things differently and the driver is set for
that way, so changing in the driver will break scale.
AFAICT this is orthogonal to the 1080/1088 encode issue discussed long
ago where ffmpeg is doing the right thing, that should be fixable in the
driver.
This case can be demonstrated with 1920x1080 nv12 hwupload -> deint ->
hwdownload, so no chance for h26x cropping info being used.
