madVR - high quality video renderer (GPU assisted)

Yeah, but there's not much reason to bitstream when you can already fully decode all formats.

Thats my problem. I need itstreaming because I own a D-Box system

If you need a Dolby Digital stream, then ReClock can encode to DD on-the-fly. Better use the lossless tracks, decode them, and let ReClock do its thing and encode to DD.

I don t fully understand this, sorry.

I ll try to explain what I want/need so you can tell if this is possible:

A D-Box decoder needs the core DD/DTS track that comes on a BR-disc to be able to 'read'. For years all D-Box owners thought that enjoy both D-Box AND high res. (DTS-MA/True-HD) audio to receiver simultanously was not possible due to windows limitations. So most D-Box users use a Dune media player. With this player audio is send out over both HDMI (lossless) and SPDIF (lossy core) simultanously.

But there has been a new D-Box user who developed an MPC-HC and LAV audio decoder which makes it possible to have two audio streams send out. One with the DTS-MA track send through the HDMI audio out of a NVIDIA/ATI card and one with the core DTS/DD track over a second audio device (a plain simple external USB audio device with just a regular SPDIF output on it). This works good until now; there are some minor fixes on his to-to list but the main feature works.

So what we would need is to be able to get the UNALTERED lossy core signal send over via the external USB audio device and at the same time send the lossless DTS-MA/True-HD that is decoded by ReClock via LPCM over HDMI and all this simultanously.

I think the author of this project will join soon here to give further explanation but the main thing is explained now, maybe not very technical but I think you will know the problem now and what we (D-Box users) need/want.

It's ok, I got it. I don't think you could do it with ReClock if you need two audio stream outputs simultaneously.

ATI is more accurate 'out-of-the-box' than Nv with refresh rates. I can go a whole movie without a single dropped frame without reclock and my refresh rate is 23.9774 (Radeon 5570). I've used Reclock for the past year or two and recently stopped using it because I found it was unnecessary.

If you really don't want to use reclock, you can play around with custom resolutions to alter the timings to get the refresh rate closer to the target 23.976. As you can see, you don't need the refresh rate to be perfect.

Here's some reading for you:

THis is great and just the solution I was looking for! I ll try this tonight. If this works, I don t need ReClock.

[kennae]

With reclock, should I use 24.000 or 23.976 for monitor when watching typical 23.976 material reclock being set to "AUTO"? I can get close to both Hz's but not sure what to use. Sorry for OT, but you guys were speaking about it anyway.
I tested both ways, even without reclock, but I want to be sure.

23.976. It is closer (even if its not 23.976) than 24.000... I recommend to use madVR internal frequency- switcher and put there all the max resolution frequencys that your TV/projector supports... Then it chooses the best for each media file...

Been using it when it came out, AutoFrequency before that. I have 24p/50p/59p/60p available and everything works great.

Thanks for clearing this up.

[pirlouy]

I think there are false answers here.

Let Reclock to Auto.
in MadVR, if your TV is compatible with 23.976Hz and 24Hz, you have the choice:
1) you allow 23.976 in madVR, then your movie will be at that rate
2) you don't allow 23.976, and keep only 24 in madVR, and then Reclock will "speed up" a little bit the video

Personally, I've chosen the 2nd solution, since several videos are "recorded" in 24fps, then put at 23.976 for Blu-Ray.
But be careful, some movies are really "recorded" in 23.976 Hz, and watching them in 23.976 would be preferable.

It's just my opinion; maybe I'm wrong. People like Leeperry knows this kind of stuff far better than me...

[Thunderbolt8]

so whats the way to find out whether a movie has been recorded with 24 or 23.976 fps?

[pirlouy]

I think you have to search and search.
Maybe some "skilled" guys reading this thread could give you useful links.

[SamuriHL]

I finally got my system back to stable after the latest nVidia WHQL driver. My settings are similar to Nev's but not identical. I had to create new custom res's for 59.940 and 23.976 again. Now it's silky smooth again. nVidia, I swear, if you touch this again.....

This seems to work fine for me. Now I can bitstream AND have accurate corresponding refresh rates. I made a custom refresh rate of 23,978, this corresponds with 23,977xx which is pretty close to 23,97600 I get a dropped frame every 16 hours in the report now.

However, I found a new problem I have tonight:
I ran the Avatar Blu-Ray disc and with this movie with MPC-HC/madVR I get heavy hick-ups every 10 seconds or so. I are not really stutters but it just looks like the player is 'hanging' for half a second.
I get no dropped frames or anything. When this hanging happens and I check madVR the line 'dropped frame every ...' disappears for just a slight moment.

Any thoughts?

EDIT:
I just found out that ALL my movies has this problem and that PRESENTATION GLITCHES is counting up heavy during playback.

Running W7 X64

EDIT2:
things are getting even more strange:
All off a sudden I get a red notification 'Creating Direct3D Device Failed (8876086c)' and madVR does not work anymore. A re-installation won t help either!

[linzki]

I'm using mpc-hc with lav filters, madvr, ffdshow raw video filter.

Is there a way to check my frame rate? because i'm not sure if anything happens with LAV video decoders deinterlacing 25p/30p or 50p/60p. Nothing seems to change when i switch between those two options.

Then if i use ffdshow with yadif's deinterlacing double framerate, i can hear fan picking up speed immediately and if i use zoom players playing information, i can see actual frame rate doubleing.

i tried ctrl+j in mpc-hc but can't see it telling me if framerate is doubeling; nothin changes if i switch between 25p/30p or 50p/60p in LAV video decoder.

i'm using GF 460 gtx, Intel® Core™2 Quad Processor Q6600, 4gb ddr3

Not recorded, but encoded. MediaInfo(Lib) 0.7 - Reading information about media files
Set ReClock to Auto, let it do its job.

[pirlouy]

No; "recorded" (or maybe it's not the exact word), not encoded. :-)

I meant, before to be on a Blu-Ray, the film has been shot at a certain frequency, this is this frequency I talk about (with my limited language).

Did these issues happen before your made a custom resolution?

Seems like a few others received this message, too.

Maybe if you post a log, madshi can help you.

Exclusive mode has started causing major problems for me in terms of dropped frames and low present then render queues. Everything is fine in windowed mode though. I'm guessing this has to do with process priority or something like that but I can't say for sure.

EDIT: Scale in linear light is the cause of dropped frames in exclusive mode is enabled in Luma Upscaling for those with CPU's that aren't powerful enough.
