RE: vaapi-sse4: Deinterlacing Testing - -DDD- - 2014-06-05
The difference would be that we have a lower CPU Load, or are there any other Benefits in VPP?
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-06-05
Yes. Quality wise it's not easy to get better than yadif.
My tests with MACI and MADI on 576i and 1080i mpeg-2 material are "okay" - but nothing too fancy. I hope that slow GPU systems like Baytrails could be able to do 1080i50 and 576i in a quality better than bob.

Given that I tend to wait for the georgeous things to come.
But anyway, based on previous posts I have pulled
Code:
[remote "origin"]
url = https://github.com/fritsch/xbmc.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin

See first post:-)
RE: vaapi-sse4: Deinterlacing Testing - Juanjo - 2014-06-06
I just noticed a mesa upgrade in Ubuntu repos, if I upgrade, will the patches from your repos to make all this work disapear and installation get messed up? Or is it safe to upgrade?
Thanks a lot.
Juanjo
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-06-06
If you are on 14.04 and had the mesa ppa running, upgrade will be smooth and you loose nothing, as we only provided mesa for trusty cause of some bugs in there.
If you already installed on 13.10, then you already have a broken system since upgrade to 14.04 if you did not remove the mesa ppa before.

Looks like an interesting release of libva coming up
http://cgit.freedesktop.org/vaapi/intel-driver/commit/?id=364d9b1968f905573bd6ae0e27d43ccdaedea4d5
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-06-10
No, see:

MADI / MACI / BOB and additionally yadif is already implement by FernetMenta on his vpp branch. On HSW only BOB works - despite that the current MADI quality looks rather shitty:
MADI-VPP:
Deinterlace-Yadif:
BOB-VPP
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-06-10
So to make some things and expectations short:
- Without massive fixing on the intel side, we don't get that running at all
- Without massive improvement of their MADI / MACI filter (currently only one forward reference) the quality won't be nowhere nearly as good as yadif / nvidia vdpau / amd oss temporal(!).
From the lib the following should work (but does not):
HSW: Bob, MACI (*), MADI(*)
IVB: Bob, MADI
SNB: Bob, MADI (**)
Baytrail is IVB - so happy testing.
* non working: see above bugreports
** not tested
RE: vaapi-sse4: Deinterlacing Testing - dr88dr88 - 2014-06-10
@fritsch
I am running Deinterlace-Yadif on my NUC with OpenElec and it is the best quality I have seen when I compare it with AMD hardware Deinterlacing on windows.
I am worried that the option will be removed when Intel fix its drivers and that I will get a worse quality in return.
Can you tell me if you are planning the maintain this nice hack in future OpenElec versions ?
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-06-10
It won't be removed. Fernet's vpp branch can do both and switch on the fly (I also don't want to miss Yadif anymore). It supports the VPP modes and additionally our SSE4.2 + cpu deinterlacing.
RE: vaapi-sse4: Deinterlacing Testing - FernetMenta - 2014-06-10
No worries that we drop the best option. And it won't be a hack anymore
RE: vaapi-sse4: Deinterlacing Testing - Frank-NL - 2014-06-10
Will it be used in OE?
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-06-11
Will you receive your pension when you are ready with fully paying it?
RE: vaapi-sse4: Deinterlacing Testing - Frank-NL - 2014-06-11
Good
