Because as far as i remember DXVA Native can work only with ur primary and active vga.

So i guess ur monitor/tv is currently connected to your CPU iGPU.

I have found software only Mainconcept HEVC Video Decoder 5.0.14.053 http://www.mediafire.com/download/kt...k1xq/mc0416.7z that pretty well for my purposes in DVBViewer - I see online slideshow of all UltraHD channels with good soundtrack when I set SkipPB and sometimes Synchronization Off instead off PTS in Mainconcept decoder's settings.
Why Mainconcept HEVC Video Decoder could not connect to LAV Splitter? Can you correct it because your LAV Splitter much more universal?

I don't use hevc but I decided to watch. VictorLS if you are using the hevc decoding on CPU use http://xhevc.com/en/hevc/decoder/download.jsp I got minus 40% from 80-96% on the CPU (amd 3391x2 hz avx1). With Strongene Lentoid decoder I have ~40% on CPU on Win 32 bit, decoder without opencl with this file. Exemple file: encoder N-80129-ga1953d4 https://www.cubbyusercontent.com/pl/...4a3030b14ae001

UltraHD - hmm, look at, they have decoder: cpu + gpu on opencl.

1) Because it was designed so by the Mainconcept developers?

2) If you pester the Mainconcept people, then maybe you'll get what you want.
The Lentoid HEVC decoder became "connectable" to LAV Splitter only after I sent an e-mail to Strongene themselves.

I don't have hevc files, I have hevc files, just to see how they look. Me don't need 2-4K. 4K on the CPU is not really use not with vp9, not with h264/avc, not with h265. Maybe can only with cpu frequencies above 3000 Hz Phenom 2 x6 or Bulldozer x8, or multi-core Xeon processors with avx512 4k will work acceptable or not bad. I never thought about it seriously use 4k. About Lentoid HEVC I know about ~8 months.

Video hevc 1080p 25 fps 1000 kbit/sec with CPU load 3391x2 hz avx1 80-96% is too much. With Lentoid HEVC decoder minus 40-56%, decode on cpu.

I have so: Lentoid hevc decoder and lav hevc decoder use the CPU is 30-50% more intensive compared with lav h264/avc decoder (s/w). Checked files with the same resolution and with the same frame rate, and with the same bitrate.

Thank you for your e-mail to Strongene.

1. Lentoid (last three version) never decrease CPU load on my computer neither in XP nor in 7x64. I don't know why. You can try my files http://forum.doom9.org/showthread.ph...45#post1726845
2. Only last v2.1.0.2_2015_12_02_r4644 of Lentoid can decode 10bit;
3. Even last Lentoid decodes bad in sat programs like DVBViewer both 8bit and 10bit (like Elecard HEVC Video decoder decodes 10bit in sat programs):

VictorLS I сommented personal message.

Lentoid hevc decoder can't create miracles. Video 3840 x 2160 (4k) 50 fps 30 MB/s this much for normal decode on the CPU. Such video files need checked for 6 or 8 (not logical cores, real cores) core processor with a frequency above 3000 Hz. On their website they have information the test, with a maximum file size of 2560 x 1600 30 fps 32937 Kbit and tested on Win. 7 Cpu i7-2600 8GB RAM from a year 2013.11

With Lentoid HEVC decoder minus 40-56%, decode on cpu, for this file and this cpu: Video hevc 1080p 25 fps 1000 kbit/sec with CPU load AMD 3391x2 hz avx1 80-96% is too much. = ~40% with Lentoid HEVC decoder load cpu for this file hevc 1080p 25 fps 1000 kbit/sec.

I agree, middle Core i7 plays that files well.

I would like these features implemented in LAV Filters: Normalize, Max Amplification 400% and Regain Volume.
Reason is sound is too low for my normal hearing on my sony headphone even with all volume settings on max and loudness equalization enabled in sound manager, equalizer did nothing too.
On ffdshow audio decoder with these settings enabled, my problem is solved but ffdshow is outdated.

Sorry, but there are no plans to offer volume processing like that.

kirakami Use the "ffdshow raw audio processor" priority prefer, with the lav audio decoder or with another audio decoder.

Taro mentions the differences for his builds in an old blog post.
https://astrataro.wordpress.com/2014...vfilters-tmod/
But that was back in 2014, now sure how the two builds compare today.

Some questions regarding deinterlacing.

1) Is there a quality difference between CUVID deinterlacing and what madVR uses for deinterlacing (which I guess it's DXVA2, judging from OSD info)? In favour of which approach?

2) Is Weston Complex supposed to be lighter on CPU usage than YADIF?

3) Is it supposed to lead to better results or simply different results and one has to judge subjectively?

Thanks nevcariel for all the good work you put in LAV Filters. If you are still in touch with tiben20, tell him Kodi users miss him enormously now that Aracnoz has thrown the towel on Kodi DSPlayer (we were missing him before too but now... it's a desperate situation).

Both use the GPU's deinterlacing algorithms, so should be identical.

Different for sure. Worse, IMO.

Isn't CUVID using CUDA, thus being programmable and potentially different from standard built in DXVA deinterlacing? Otherwise I wouldn't understand why is deinterlacing through LAV only selectable when using CUVID and not when using DXVA2 CP with Nvidia cards.

Looking at your previous posts, do I understand correctly that you place hardware deinterlacing as the best solution?

DXVA deintelancing is possible too with DXVA decoding but lavfilter doesn't support that.

nvidia would be pretty dumb to write two different deinterlancer.

and who said that DXVA decoding can't use CUDA too. the hybrid decoder are using CUDA nearly for sure.

Nobody said anything. I think I was pretty clear about my ignorance, by asking information here.

nevcairiel did not answer my question about Mainconcept too
I am sure he saw it
May be it is impossible to realize in LAV Splitter (but I am not believe in this version).

Nev,

Thank you for implementing MVC support in .m2ts container i am happy to report that in your last nightly my 3D .m2ts files are indeed reported as 3D in madvr, BUT (there is always a "BUT" ) playback is jerky and picture is often getting corrupt with pixels and recovers after a while.

FYI same movie inside .ssif container is playing fine, the moment i remux it into .m2ts the issue appears.
