Sounds like you enabled Bitstreaming in LAV Audio but your audio renderer does not accept bitstreaming.

Yes, I did actually and my Audio Renderer should support it. Anyway, I disabled it then it surprisingly identified LAV Audio Decoder which output it as PCM! I guess I should be good to go. Thanks for your precious input, buddy! Last edited by salam2009; 2nd December 2015 at 01:42. |

Yes, (since we can't separate acceleration process from 2 cores, and my default player is assigned to nvidia), I just double checked it with few 2160p samples (on 1080p display) (I use the nvidia gpu in an underclocked state (470/800 vs 745/2000 (default))):
1. in underclocked state: - DXVA Copyback direct can accelerate only: 24fps 33Mbitps, 25fps 16Mbitps - CUVID can accelerate : 30fps 16Mbitps, 24fps 130Mbitps (!) 2. in default state: - DXVA Copyback direct can accelerate only: 24fps 33Mbitps, 25fps 16Mbitps, 30fps 16Mbitps - CUVID can accelerate : 24fps 130Mbitps (!) (Bitrates are average bitrates according to mediainfo, bit it could get really high so that's when copyback fails.) I understand that this is an extreme case, just wanted you to know how CUVID vs copyback behaves on my system. Quote:

MPC BE 32 / MPCHC 32 use Lav 32 (Splitter/Audio/video) MPC BE 64 / MPCHC 64 use Lav 64 (Splitter/Audio/video) So to answer your question, use a 64 bit player

think about quicksync. 25 FPS up to 16 mbit is a joke... |

Bit of a testing report. I managed to get a sample of UHD 4K content in HEVC with 10 bit colour in level 5.2 using a very high constant bitrate at 60 FPS. Its 3840x2160P60 as in the 4K TV standard not the cinema 4K. Using an old sandy bridge CPU and a Nvidia Geforce 960, setting the nightly x64 LAV filters with the nightly MPC-HC builds, on my 4K display I see it render smooth and flawless. I run DXVA 2 in native mode using the EVR CP. At 60 fps it takes around 16.6 ms for each frame, and Im pleased to say my max paint times in MPC-HC barely exceed this at around 25 ms, with most frames - well just about all of them - being well under the 16.6 ms cadence at 5 ms. I notice a CPU utilisation around 7% and the GPU video engine peaks at 62% max, the gpu core peaks at 61% and on my 2GB card, the video ram use maxes out at 75%. Overall its a very pleasant experience with excellent video quality, crisp and sharp, played back using barely any CPU and the GPU doing the grunt. Even with 60 FPS material of such complexity its all smooth.

I know, but it was for testing purposes.
If I use quicksync then I'm forced to use iGPU. So it's not enough for madvr

I'm curious - what would you call a slow cpu? I have a Core 2 Duo E6600 (2.4 ghz) on a GeForce 550 Ti. Of course there are other variables like scaling, but I've found in testing that software decoding is slightly faster than hardware (lower madvr render time in the 0.3 ms range...really nothing). I guess it is machine dependent. 550 Ti is still pretty good

madVR's render time is not decoding time, madVR's OSD does not display video decoding times. A Core 2 Duo is a slow CPU today but still fast enough for 1080p H.264 software decoding, 4K or HEVC might cause you some trouble though.
Of course madVR will run faster when it doesn't have to share the GPU with DXVA2 decoding. DXVA2 decoding uses dedicated hardware on the GPU (not shaders) but it still impacts madVR a little bit.

Hi, whats the situation with VP9? During playback the EVR-CP renderer stats says its not using DXVA. I thought the GTX 960 gpu supported VP9 in full hardware GPU accel? Thx
EDIT: DXVAChecker says VP9_VLD_Profile0: DXVA2/D3D11, SD / HD / FHD / 4K so its in the GTX 960 hardware for sure Last edited by Nullack; 3rd December 2015 at 08:41. |

LAV does not yet support VP9 DXVA. The author said he's already working on it, though.

The latest NVIDIA driver also seems to not support VP9 properly yet.
