Resize and degrain? read my posts above i said when the system is under stress, not when the system "never breaks a sweat" talk about the complete opposite!! I guess your not using mvtools with 16 8 and 4 blksizes then. Try that on 1080p in real time. Why do people always come and say x works for me or it always runs fine here when other people clearly say something doesn't for them. In any case does it matter what external filter one uses. The point is madvr will drop more frames than evr when the machine is on the limit. Either we must reduce the processing done outside of madvr to compensAte or madvr reduces it's processing. It seems this isn't possible so theres nothing left to discuss. It's no piece of softwares fault just a fact.

I think mark is referring to a frame doubling script such as this. (turns 30fps into 60fps, 24fps into 48fps etc.) I tried it once and it definitely stresses the CPU to the limit. It definitely gives the video a unique look and it's definitely a desired taste. (it kinda gives the "soap opera" effect)
SetMtmode(2,10) source=ffdshow_source() source=changefps(source,source,true) # assume progressive PAL 25 fps or NTSC Film 23.976 source backward_vec = source.MVAnalyse(blksize=16, isb = true, chroma=false, pel=1, searchparam=1, idx=1) # we use explicit idx for more fast processing forward_vec = source.MVAnalyse(blksize=16, isb = false, chroma=false, pel=1, searchparam=1, idx=1) source.MVFlowFps(backward_vec, forward_vec, num=2*FramerateNumerator(source), \ den=FramerateDenominator(source), mask=0, idx=1) distributor()

Ah for 1080p post-processing...Well, that's a different story. Get a more powerful cpu or overclock I guess. I won't deny that I can't post-process with heavy filters on a 1080p stream but I think that's mainly due to the fact that I'm on a C2D vs. a oc'd quad, i7, or even hexacore.

The whole screen turns black for a moment and then MPC and any other windows that are open redraw themselves, this occurs over a couple of seconds. |

Your problem appears unique to only you, since no one else in this thread appears to be have high CPU issues with madVR. Quote:
The following are my suggestions for troubleshooting, please do all of them: Uninstall FFDshow and DivX decoders. Uninstall Haali, LAV, and DivX splitters. Uninstall madVR and delete the settings.bin Open MPC-HC and disable ALL internal filters. Restart your computer. Install Haali as your only splitter. Install FFDshow as your only decoder. Install madVR. Playback a MKV with MPC-HC and madVR. Open madVR settings. Set all resizers to Bilinear, Disable Fullscreen Exclusive, and set all Windowed Mode Tweaks to Don't Flush. Close MPC-HC Playback a MKV with MPC-HC and madVR once again. Does the problem still exist? If so, download Process Explorer, run as administrator, double click on MPC-HC in Process Explorer while playing an MKV in madVR, click on the Threads tab, and take a screenshot of the Threads tab (PrtScn & paste in MS Paint) when you are seeing High CPU usage. Take a screenshot of your entire Process Explorer window during high CPU usage. Navigate the menu View -> System Information and take a screenshot of the System Information window during high CPU usage. Post all three screenshots here. Hopefully that should give some insight to the cause. I'm somewhat suspecting it's a LAV or DivX MKV splitter issue. Last week when I tried LAV splitter with madVR, they didn't get along at all. If madVR.ax is really to blame, it should show with high CPU use in the Threads tab screenshot. In which case, there may be a bug of some sort which madshi needs to fix.

As for your troubleshooting tips, thanks, been there done that: - This is not a codecpack-infested machine. - Although it's not an apple-vs-apple comparison, madVR performed in XPSP3 the same as it does now in Win7 SP1. - Most importantly: I'm perfectly happy with madVR |

Can anybody reproduce any problems with FLV files in Windows 7? There were 2 different people reporting problems now, so it should be credible. Quote:

My post linked above gives a bit more info on those two issues for anyone trying to reproduce them. |

Interestingly enough I can reproduce problems with the internal flv splitter, ffdshow and madVR. This is almost for all FLV files I have now. I thought it was a corrupt file or something but it doesn't happen with EVR-CP.

madshi, I know you looked into this before, but am unsure if you checked it recently. When starting a movie with madVR, I usually get between 4 and 20~ frame drops, randomly falling somewhere in between these. If the very start of the movie, ie the first second, actually contains some content, obviously we will see a noticible judder effect.
Is this something madVR can control, ie can it wait internally for a period of time for whatever causes the frame drops (buffers filling maybe?) to be completed before beginning the rendering process.. Obviously this would be very low priority but just aiming for perfection it would be great to start a clip and see 0 frame drops in the first second or two. |

I don't have a GPU which supports H264 hardware decoding.

Don't know if anyone can point me in the right direction, but I have very frustrating issue with an XP where I start to experience serious delayed frames with MadVR after about 40 minutes of playback no matter what the source material is.
For the 40 minutes or so playback is superb, a maybe 1 or 2 dropped/delayed frames at the start of playback and that's it, but after the system has been running a while, frames start to get delayed at an alarming rate (5 a second). A reboot always sorts it out. I have checked the GPU/CPU/Memory use with various tools and they all seem minimal, but it is like a driver somewhere on the PC goes skew whiff after a while. The PC is XP SP3, Athlon x64 Dual 5000+, 2gb RAM, 2gb Geforce 430, multiple hard disks running on an NForce 630/7025 based motherboard. Playback is always on Mpc-Hc. I am going to do some more investigating this weekend, but any pointers as to what in general causes the delayed frames might give me a headstart. |

Bjd are you usIng reclock? I had issues before when using it when it didn't and still doesn't detect my monitors refresh correctly and started changing the media playback speed in weird ways. Just something to check.

Yeah,I just wanted to make sure nothing was borked on my rig.Since your cpu is about 9% more powerful than mine,your numbers make sense (At least for .264 1080p but for .264 1080i,ouch ! Seems that Coreavc outperforms very noticeably your actuel decoder.) Still,I don't understand how you managed to evaluate the madVR cpu usage.You were speaking about a 3% but I might have completely misunderstood your post... |

now that I have access to my forum account and I can post I'm glad to report that all GUI draw issues with ZoomPlayer are fixed with v0.42
now if only I can find what's causing the access violation when going to the next file I'll be one more step closer to the home theater nirvana |

I've recently installed madvr after reading for it's excellent pq (congratulations @madshi)!!
I updated today to 0.42,using mpc-hc and ffdshowand i'm going to do some tests...the resizing is done to 1280*720 in ffdshow because i use an avisynth script to interpolate 23.976->59.94.... Are there any benefits of using exclusive modein madvr?does it "bypasses" any "dirty" processes that may occur in the os during the playback? i realize that aero is disabled when in fullscreen exclusive mode but there is an option to leave it enabled when we are not in exclusive... Till now i used evr cp,D3d fullscreen mode and full floating point processing enabled in mpc-hc options with aero enabled...so i'd prefer to start my tests with aero enabled.. Can i do that when in exclusive mode? Thanks! |
