RE: vaapi-sse4: Deinterlacing Testing - ant_thomas - 2014-07-18
I believe I have.
There's no "De-interlace" option when VAAPI is enabled. Just Auto-select, Bob and Bob (inverted). "De-interlace" only appears when using software decoding.
There's also no options for
Use Mpeg-2 VAAPI: Yes
Use Mpeg-4 VAAPI: if you like
UseVC-1 VAAPI: off
So I imagine I'm not using a build with these changes.
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-07-18
I have no idea which OpenELEC version you are running - but OpenELEC 4.0 has the Option "Use SW Filter", Deinterlace can only be used in this version when that option is enabled. It's hidden in Experimental hierarchy.
All newer version, which run the code of the first page don't need to trigger that setting seprately, cause it can be switched on the fly - directly from selection screen.
RE: vaapi-sse4: Deinterlacing Testing - CrazyCoder - 2014-07-18
Live HD TV channels have stopped working after updating to the current build (I didn't update for a month or so).
SD live channels, FullHD local videos still work just fine.
Any ideas?

Known ... found ... and will be fixed.

RE: vaapi-sse4: Deinterlacing Testing - CrazyCoder - 2014-07-18
Thanks for the information. Reverted to the June 30 version from apt cache and it works again.
RE: vaapi-sse4: Deinterlacing Testing - ant_thomas - 2014-07-18
Currently using
OpenELEC_Helix (official) Version: devel-20140611170617-r18580-ga84b926

RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-07-18
Most likely the patch was not integrated ... use a 4.0.7 build and you will get it.
RE: vaapi-sse4: Deinterlacing Testing - ant_thomas - 2014-07-18
Apologies, I'm an idiot. I only had Advanced settings enabled and not Expert.
Well it looks like the Intel J1900 isn't fast enough to do yadif well enough with VAAPI enabled but it's fine when using full software decoding which is nice to know.
Stable 50fps with all software
30-40 fps with yadif and vaapi
(You probably know all this already though!)
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-07-18
Yeah the J1900 has probably the worst GPU that you can imagine ... intel fucked that up completely.
VAAPI + YADIF won't work on this J1900, cause the GPU is under too much load when doing decoding + rendering ... it sucks balls :-)
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-07-18
The only thing we got to work "gpu only" is VAAPI decoding + VAAPI BOB, which is not in your current version.
RE: vaapi-sse4: Deinterlacing Testing - ant_thomas - 2014-07-18
But it handles it all fine in software which isn't so bad I guess.
Shame I can't get the nvidia 820m graphics in my Asus EB1037 working alongside side it!
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-07-18
Yes - the CPU is really okay. GPU is stressed to death in the above scenario.
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-07-18
Can you play this one, please (with VAAPI and with your swdecoding): https://dl.dropboxusercontent.com/u/55728161/1080p50-recode.mkv
Skips, Drops?

Maybe it gets better when Intel improve their Linux drivers?

The GPU seems to work good under Windows:

RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-07-18
Hopefully ... File a bug on freedesktop and tell them that the Baytrail GPU is currently unusable ... will get funny to see the reply :-)
