I will do as what you said above once I am freemadshi
PS:my displayer refresh rate 50 or 60Hz,movies fratemate is 4 frame , 5 or 8 ,too

Any possibilty of getting CPU (GPU???) usage in the CTRL+J OSD?

[moliko]

after long 5 days

using: mpc-hc, ffdshow, lavsplitter, madvr
i got problems with sounds playback of aac (lc) & pcm (big/unsigned) in mov and mp4 container
the sound is scratchy and many clicks and pops
when i change back to evr renderer i have a clear sound

And now i have scratchy sound in some mkv with ac3 too, i got this terrible sound only in combination with madvr.

but i like the damn good video quality with spline

i do not like change back to evr in some files

how can it possible that madvr destroy my sound

here is a sample of my sound
it sounds to me when i use madvr

[Mark_A_W]

madshi, the disable desktop composition setting (obviously when the PC has Aero enabled), drops it to 60i, rather than 96i. During the black flash Powerstrip is disabled somehow - in a similar fashion to when you install a program and it all goes dark for the prompt question.

My workaround is to turn of Aero completely, just thought you'd like to know.

First of all, a big for this wonderful software!

A quick question, after updating my ffdshow, madvr, resetting MPC-HC I have everything working pretty well. Using the lavsplitter and Arcsoft HD audio decoder to get DTS-MA, too. My rather modest setup (ATI 5450, Win7, 2.4GHz CoreDuo CPU) can play all but the most demanding material (i.e. Avatar).

My question is when I launch MPC-HC from within XBMC, it comes up in full screen, but not exclusive mode. If I bring up the settings window for one of the filters and then close it, it will switch to exclusive mode and all is well. Not sure if this is a madvr issue or MPC-HC?

Some remarks about vc-1 stream in m2ts container.

.56, W7, 5750, 11.3, MPC-HC, Aero on

8 prepresented frames
Cyberlink 10 decoder - madvr reports unknown fps, very smooth, no dropping frames
MPC HC decoder - madvr reports 23.976, very smooth, no dropping frames
WMV decoder - madvr reports 23.976, many dropped and delayed frames

4 prepresented frames
Cyberlink 10 decoder - very smooth, no dropping frames
MPC HC decoder - very smooth, no dropping frames
WMV decoder - very smooth, no dropping frames

16 prepresented frames
Cyberlink 10 decoder - very smooth, no dropping frames
MPC HC decoder - very smooth, no dropping frames
WMV decoder - many dropped and delayed frames


madshi for all!

What is your CPU usage like? Usually that is the cause of audio problems.

I have never found the WMV Decoder to have smooth playback with madVR and use libavcodec.

Hi,

terrible glitches on your setup. Pls download this utitlity, run it with madVR and EVR a post both results:
http://www.thesycon.de/deu/latency_check.shtml

I have reported DPC issues with madVR a 2 months ago. Some sound chips can handle the sound also if DPC peaks are occuring - without any sound glitches. This is the case of my motherboards Realtek ALC889. But my main soundcard, RME Babyface does not like DPC latencies at all - I hear occasional dropouts ( not like yours ) when mpc-hc with madVR is running.

The difference in DPC latency between EVR and madVR is here to see:

http://img220.imageshack.us/f/madvrdpclatency.png/

Till date I havent found out, what is madVR doing differently from EVR CP that these DPC latencies occur. My CPU is i7 980x where madVR setup runs on 5-7 percent (0.56)

Plutotype,
I've just checked it and the latest version of madVR is not giving me high DPC latency ... it's either fixed or it could be that I've recently changed my video card to NVIDIA ... if I have more time tomorrow I'll test with the old version of madVR, which I used when I had the problem a few months ago, and report

I try today with other movies and I have lots of glitches even without ctrl+j function activated.

Your new exclusive mode function doesn't work with my computer since madvr 0.51.

Is it possible to correct this problem?

With madvr 0.5 it works very well.

here another system pic in was i change my cpu back to X2

as X2 he is still able to play 1080p vids with spline

running XPSP3/8800GS and a USB audio transport(Firestone Bravo), I only get spikes when going FSE<>FSW. They're not red, and they don't make audio glitches:

Have you tried to lock the clock speeds of your CPU/GPU?

Hi Leepery,
Yes I have tried everything. Will try to swap the graphics for another model, because users Moliko and Pankov had also Sapphire graphics ( 5670/57xx ) and we all have experienced DPC latency spikes. Just an idea, dont want to discuss it here more.

Anyway, 0.56 rocks, yesterday watched 140min movie a at the end pressed ctrl-j: zero dropped frames and 1 dropped frame in 15hours. Nice.

[leeperry]

It used to be possible w/ <0.50 to switch refresh rates on the fly, but now all I get is a black screen and PotPlayer's frozen. This can't be good for Reclock users

Well at least it is not just me! I'm using the "old path" at present and really looking foward to the addition of refresh rate changing as a part of madVR!

Makes no difference to quality. Might impact speed slightly.

The only options that impact quality are those in the "trade quality for performance" section (leave them all unchecked, if you want max quality) and of course the scaling algorithms (choose the algorithm which is most pleasing to your eyes, there's no "best" algorithm).

All other options do not affect image quality. Unless you have tearing or non-smooth playback in windowed mode. In that case I would suggest to use the exclusive mode.

I do remember right around the time the 500 series launched, that I tried to install the driver for one (normally I don't bother to select my GPU on the Nvidia site as they're supposed to be universal) and it said it was incompatible.

I have experimented with the flush settings and it seems that anything that stops the present error from happening (pretty much sleep/loop on "after copy to backbuffer") then causes my previous issue of the buffers gradually dropping to 0, or near-enough and having constant dropped frames. No combination seems to fix both.

As mentioned before, I only get these present errors when the refresh rate and video framerate are not matched 1:1.

24p film at 24Hz is fine, 25p film downclocked to 24Hz is fine, 25p video at 50Hz or 30p at 60Hz is not. Unfortunately I don't think my display accepts 25Hz or 30Hz.

Very weird. My 9400 seems to work best with all flushes disabled and 10 pre-presented frames. With these settings I have about 2-3 pretty much invisible glitches per movie when playing back 25p film on 50Hz. I've no idea why your 570 makes such problems. You're the only madVR user who seems to have these "present errors". Maybe reinstalling the driver version or trying a different driver version might be worth a try?

A while ago you mentioned that the old rendering path was scaling chroma directly from the source resolution to the target resolution in a single step, and that the new render path you were working on would scale chroma to the luma resolution, and then scale chroma & luma to your target resolution using the selected luma algorithm on both.

Has this been implemented?

Not yet, but it will come very soon now.

Not anytime soon. Too much other important stuff to do.

How about FLAC? DTS? Does it apply to all audio codecs and containers or only to some? Have you tried different splitters and/or different decoders? Maybe a different audio renderer?

In theory madVR does not do anything to audio.

If you create a debug log for me I can have a look at why it doesn't go to exclusive mode. Try to keep the log short, please, as in: Delete any old logs. Then start MPC-HC so that it doesn't go exclusive (although it should). Let it play for 5 seconds in windowed mode. Then exit MPC-HC. Then zip and upload the log somewhere.

The reason why it's smooth with 4 frames is that the decoder queue is not fully utilized in that case by the presentation queue. Once the frames are presented, they're out of madVR's hands. With only 4 pre-presented frames, 4 frames in the decoder queue are always still under madVR's control. Which allows madVR to "repair" any faulty timestamps.

The *real* cause of the problem is a faulty splitter, though! Choose a good splitter, please, and you'll have perfectly smooth VC-1 playback with the MS VC-1 decoder + madVR with 8 or 16 pre-presented frames, too.

Then you've probably never used a correctly working splitter yet. Try playing back VC-1 MKVs created by eac3to by using the Haali Splitter. That gives me perfectly fluid results with the MS VC-1 decoder and madVR. When muxing MKVs by using eac3to, eac3to is responsible for creating the timestamps. If you then use a splitter which simply outputs the timestamps as they are without fiddling around with them, you should get perfectly smooth results.

With madvr 0.5 it works very well.

Do your eyes tell you that v0.56 is less smooth than v0.50? You can't trust the v0.50 statistics because v0.50 was not able to detect glitches at all.

The only possible reason I can imagine why madVR could cause DPC latency issues is that I'm reading the VSync scanlines in a thread which runs at very high priority. Maybe this thread interrupts the audio drivers too much sometimes, depending on how they're written. I could probably lower the thread priority, but then eventually video playback could become less smooth (not sure).

This seems to be caused by the VSync scanline reading stopping to work sometimes. I've done some changes in that regard in newer versions which actually improve things in certain situations. But it seems things got worse in other situations. I'm playing around with using a different scanline reading API now. Maybe that will fix things completely. Or not...
