There seems to be an exception in avcodec-lav-53.dll when using the filter without registering it: http://pastebin.com/DQGu1whV
When it does work though: http://pastebin.com/qyXdgLem Edit: On a side note, the tool tip for multi-threaded decoding is missing punctuation in codec names here and there (mostly periods and dashes). Last edited by Snowknight26; 12th January 2012 at 00:05. |

Two samples, both high bit rate bluray rips.

What version intel driver are people using with QS?
I've tried both 2509 & 2559 and they both stutter in hatdware and software mode. The only one that seems to work at all is 2372 in software mode only. While hardware mode on 2372 does that wierd frame flicker. Specs are: i3 2100 on asrock z68m/usb3 using win7 64bit. With dsplayer in xbmc (hardware & software) and mc17 (software only) to verify it's not just the player. |

1. As a ATI user, Thx nev first.
2. I simply tested all 1080p and 1080i I have(BD files .m2ts). 3. My M hd4650(UVD2.0) supports H.264_VLD, VC1(WMV3)_VLD, MPEG2_IDCT, the project for ATI only works on H.264 and VC1(WMV3), MPEG2 failed, just like MPC-HC whose DXVA is only based on VLD(Variable Length Decoding). 4. Compared with H.264, VC1 files perform poor,not very smooth(Same is CUVID).. Yep, 1080p's playback is better than 1080i too. 5. Everything(except VC1) seems to be running smoothly, I only found one 1080i/H.264 clip(Image is broken) .Maybe you can try it here. Mobility HD4650, Catalyst 12.1a preview, win7 x86 H.264 1080I(Image broken) VC1 WMV3 MPEG2 |

From all these numbers it looks like anything up to 60i will most likely play properly, however 60p might be too slow, somewhat similar to my own results.
We'll see if i can find a better way to lock and retrieve the video frame. I didn't even optimize the memory copying yet because all the time is spent in LockRect, not copying the data. I must be doing somethign wrong still, because even on my NVIDIA the performance isn't close to what i would expect. Does anyone have any experience with copying the data from the GPU? Right now i'm just LockRect'ing the DXVA surface and copying the data over - but the LockRect can quite frequently take a long time. I read that an alternative is using GetRenderTargetData to copy the data to system memory, and because that method is async in the background, i could potentially gain some benefits from it? PS: Partial acceleration is annoyingly complicated to support for only a small gain, which is why its not supported and never will be. Even Microsoft got the hint, and any new formats don't have a partial acceleration type (and won't have).

2. The 64 bit version of MPC-HC. Yes. We all know that 64bit player cannot run a 32bit renderer. I was asking: "why not install the 64bits components of LAV Filters?" (so that they will be available for other [64bit] programs) 3. But why? LAV Splitter does a much better job. 4. Well, wasn't this a "newbie" guide? Adding ffdshow to the filter chain would be be useless for 99.999% of the users, since they don't even know what video post processing is or how to setup it properly. 5. It doesn't mess up the MPC-HC GUI. The move to exclusive full screen is just fine (does the quick "flash" really bother anyone?). They must have forgotten exclusive mode results in a much smoother playback (which is one of the best features of madVR). |

LOL
I spent a week going around in circles trying to find an easy step by step install guide and i've just found it at the very page i first started at, nevcairiel own HomePage. http://1f0.de/lav-cuvid/guide/ nevcairiel is there any chance you could make this guide more obvious in the first post of this thread and on the start of your webpage so newbies and people with low computer skills such as myself can avoid the obnoxious comments from users when asking for guidance as if LAV filters is some how for the elite and you need to search and read about codecs and splitters before you can use it.As all we need to know is what to adjust and tick/untick so we can just get on and use it and your guide does that prefectly. Plus the more accessible it is and the quicker we can get going the quicker newbies can hit the paypal donate. Thanks |

The weird thing is that the locking speed is not consistent, its going like 20ms, 1ms, 1ms, 20ms, 1ms, 1ms .. as if its still decoding a frame there and waiting. I'll see about running more tests later.

No, because the guide is outdated, and LAV CUVID has been deprecated.

I write code, not guides.
