Regarding the failure of exclusive mode when playing from a playlist of multiple files of various frame rates and resolutions:
I have a few more observations to add. First, the failure seems to happen when switching from a 29fps to a 24fps (or vice versa). I thought it might have been when switching from an SD avi to a 720p mkv, but after tracking the problem for weeks I have narrowed it down to a frame rate change. Secondly, I was toying with the idea of using "Disable Desktop Composition (Vista or Higher)" since I did not think having a composition frame rate of 60Hz worked well with a monitor resolution of 24Hz... it just seemed wrong, I might be fooling myself however I thought I would see what would happen when enabling this setting. Guess what, there was not one instance of exclusive mode failure during a very long playlist of varying frame rates. So I may have solved my "exclusive mode failed" issue by accident by testing a setting for another reason. I just thought I would share my observations. QB

To clarify, this technically does not work with DVDs right? madvr works as the renderer in my case, but will not decode
Like 6233638 says, File > Open Disc uses Microsoft DTV-DVD automatically and blocking that uses internal MPC-HC one which is poor. The only problem with the Microsoft one was lack of navigation and subtitles, quality was fine IMO. In ffdshow I have MPEG2 decoding (libavcodec, 'DVD decoding' ticked), NV12 output, and using the 'set interlaced flag in output media type' option. This combo seems to activate the deinterlacing on my gpu as I don't have it setup anywhere else. Err is that correct? Last edited by JarrettH; 6th November 2011 at 06:38. |

Did some more deinterlace testing on my HTPC and it looks pretty good. The issue with the dropped frames is less frequent on this PC and the queue fluctuation seems to rellay only be the SD stuff (worse was the DV-AVI material in 720x576/50i). All the HD material (1920x1080/50&60i in VC-1 and h264 as well as MPEG2 1440x1080/50i) had rock solid queues.

This should happen only if you have the madVR debug OSD (Ctrl+J) active. Without the madVR debug OSD the subs should not disappear if you pause the video. Which media player are you using? Quote:

How do you know? Does Ctrl+Alt+Shift+D claim deinterlacing is off? And you can't turn it on? Quote:

When you restore, you don't see the image part of the video playing super crazy fast to catch up with the audio?
That the image hasn't been refreshed since you minimzed 1 minute prior?

I'm losing my latin here.. ^^;;
Here is a debug log. I start playing a video, minimize the player for 15 seconds, then bring it back up. When bringing it back up, I clearly see the video going uber fast to catch up with the audio.

got little bit better results 5 mins ago. I could get the 29.97 fps AVC video to play (almost?) smoothly with queue number of at least 3. (coreavc 16.7mbps) same settings as yesterday (nearest neighbor + trade quality setttings). the VC-1 video was so-so (videodecoderdmo). for ~2 seconds the queue numbers are fine, but then they drop again. repeats all the time. though when I tested the AVC video again just 1 minute later, it wasnt playing smooth any more as before. queues again down to 1, even though I didnt change any setting. both vids seem to play fine or ok when I deactivate deinterlacing with these settings. (a bit better in fullscreen mode) in catalyst settings amd overdrive is ticked, but values are set to default. setting the clock values to max or unticking the overdrive option doesnt seem to change anything though. btw. when using the madvr video decoder, subs (directvobsub) dont seem to get loaded any more, though they do with LAV video for example. (has it always been like that?) btw² ffmpeg has "VC-1 interlaced decoding" listed in their changelog for the next version, so hopefully we have interlaced vc-1 decoding soon (and hooooopefully multithreading support)

Weird problem with Windowed Mode (MPC-HC and jRiver). Source interlaced SD NTSC Video. I get good numbers for the decoder, upload and interlace queues, but the render and backbuffer queues are 0-1 and it drops about 50 frames/second. When I switch to FSE, everything is golden, queues full and playback is "flawless", zero dropped....
I've created (and emailed to you) a log with playback start in windowed mode, about 5 seconds of playback, then the switch to FSE mode. EDIT: Argh, I think this might be related to GPU downclocking, it's happening on all my sources now..... Anyone else with ATI seeing anything like this?

I think I posted a sample from this before, but this should also be film. This was back when I tried getting 29.97 IVTC'ed to 23.976 but couldn't get it working correctly. http://www.mediafire.com/?p60jl7wc61lxa3b Quote:
It looks like that is not the case. Previously, I had been recommending disabling the MS DVD decoder for mod-free DVD playback because the MPC-HC one allowed you to force weave deinterlacing, which was fine on "good" titles where that just worked, but disastrous on "tricky" films. Because that was performing deinterlacing itself, madVR disabled its deinterlacing. (as it should) It looks like madVR will perform deinterlacing if you use the MS DVD decoder though. So with an external filter list of: DVD playback is working and madVR does the deinterlacing. The ffdshow Audio Processor should not be necessary, I use that to downmix audio for headphone output, otherwise ReClock's WASAPI output complains. (I wish there was a better option) I have ReClock selected as my audio renderer, and madVR as my video renderer in the Playback > Output section of MPC-HC. The filter list when playing a DVD ends up as: ReClock Audio RendererNo DLL modifications necessary. EDIT: And I've just done a quick test in windowed mode, performing deinterlacing in a separate thread seems to improve performance here. Deinterlace Queue goes from 6–9/9 to 7–9/9 Render Queue goes from 5–8/8 to 6–8/8 Backbuffer Queue goes from 4–7/8 to 5–7/8 Last edited by 6233638; 6th November 2011 at 16:31. |

I'm gonna switch to NV again later today to check these issues more thoroughly and let you know better.
