madVR - high quality video renderer (GPU assisted)

[mochevolete]

ops, sorry, forgot to mention, just tried a couple of Blu-Ray encoded in AVC, CPU usage is about 55%

ok, in Codecs: H.264 > libavcodec
Output: Planar YUV > only YV12 is checked (is this ?)
Packed YUV has everything checked, so is RGB, do I have to uncheck all ?
No other filter is activated, nor Shader

I'll set the other things in MPC_HC,

thanks for now

[noee]

I would set h.264 to ffmpeg_mt for higher bitrate material
Uncheck all output formats except YV12

[mochevolete]

OK, the "trick" was to set ffdshow as external video decoder and .. to set ffmpeg_mt instead of libavcodec,
unfortunately is VERY prone to crash if I alt-tab to other apps, and once it crashes I have to restart the system coz the audio goes in loop.

BTW in fullscreen works perfectly, why madshi says it can't ?

re-reply, unfortunately it's not yet perfectly fluid compared do EVR custom and DXVA,
anyway, thanks for this great enhancement madshi !

madVR has it's own queue.

I think he refer to exclusive fullscreen?

For Nvidia users, Do we need a madvr update/fix or newer drivers ?

I think a madVR update will be much more exciting.

The madVR's color processing and Lanczos3 scaling make it still my preferred video renderer for AVC/H.264 contents. To me the most stable one is still v0.9 (especially for seeking). Fortunately the huge horse-powered 260GTX+ can handle it well under most situations.

For MPEG-2 contents(DVD, HDTV), I still feel the nVidia PureVideo MPEG2 video decoder + VMR9 renderless mode under WinXP produces better image output. For MPEG-2 1080i content which are native to my PDP TV display, any other combination w/i or w/o madVR never produces the same detailed and vivid-color output if compared to PureVideo decoder.

Unfortunately madVR cannot accept DXVA input, and thus it does not seem able to turn on most advanced video post-processing in GT200. (Ex: pixel adaptive deinterlace, de-ring, de-blocking, noise reduction...)


In addition I found that MPC-HC new EVR sync mode has improved a lot in D3D Exclusive mode under WinXP. It now runs smoothy for FILM content's frame playback at 1080p24 output unless the weird a/v sync logic sometimes still makes the screen frozen for several seconds. Anyway it does not produce such result if the output is 1080i60 or 1080p60 for FILM contents.

So I guess once madVR has the D3D Exclusive mode and functional OSD pin implementations, the entire playback system could become more mature with MPC-HC + madVR.

FYI - JR Media Center is adding support for madVR - http://yabb.jriver.com/interact/index.php?topic=55933.0

Has anyone yet had the opportunity to try one of the "new" 5450 or 5570 cards with madVR?

well i gave the renderer a shot again, still crazy tearing on my 9400 with latest 196 driver, but the videos start every time at least hope this will work better with a new release, i really am looking forward to it

[mikelebron]

Yea.. its unusable with my 9400 also...

well the 0.09 version has been working very well for me even with 24hz, unlike 0.11 which tears all over the place even on my 4890, i'm sure this will be fixed someday

Personally I think the 9400GT is just too weak to use with madVR.
It only is able to hit 67.2 GFlops in shading performance and the 128bit memory controller only has 12.8GB/s of bandwidth.

For nVidia's line, madVR really seems to need >200GFlop of shading performance and at least 512MB of memory with >50GB/s of bandwidth to use all its scaling options and features.

The 9600GSO 512, 9600GT, and GT 240 (DDR5 version) are probably the lowest common denominators of nVidia's line that will work well with madVR.

[namaiki]

My 9600M GT works fine with MadVR .11 @ 1920x1080 32-bit 60p with MadVR default settings(if there are more GPU intensive features, I can try them if you would like).

Specs:
32 Stream Processors.
500 MHz core clock.
1250 MHz shader clock.
800 MHz memory clock.
256MB VRAM.
128-bit memory interface.
25.6 GB/s memory bandwidth.

I think it's 120GFlops..

Using a 3dlut:

Try scaling a 1920x1080 video to 1280x720 (or 1600x900) using Spline64 for luma and chroma.

Also try scaling a 1280x720 video to 1920x1080 using Spline64 for luma and chroma.

Try playing back a 1920x1080 video at 1920x1080 with Spline64 set for luma and chroma.

If you have a bigger display handy, try scaling a 1920x1080 video to 2560x1440 with Spline64 set for luma and chroma. This seems to require >512MB of ram.


If you really want to kill your GPU:

Try playing back a 1280x720 at 1280x720 60fps video using Spline64 for luma and chroma.

Try playing back a 1920x1080 at 1920x1080 60fps video using Spline64 for luma and chroma.

Try scaling a 1280x720 or 1920x1080 60fps video using Spline64 for luma and chroma.


If you see increasing dropped or delayed frames during playback and/or the render queue drops below 8/8 , your GPU isn't powerful enough.

well that's strange, one time i launched the 0.11 version changed some settings and a movie played without a single hiccup with coreavc 2 and cuda enabled, i launched another one, choppy as hell, every resampler was set to bilinear, i don't know where this randomness comes from if 9400 is weak, which i'm sure it is, it handles the 0.09 version at 24hz and cuda enabled very well, so unless something was drastically changed in the next versions i don't know why the latest ones shouldn't work, 256 mb vram on my setup

Yes, I know that from my experience 1920x1080 appears to be the limit of a 256MB card.

Fine without 3dlut. With 3dlut, render queue will drop. Oh well, it's my laptop and only computer with a half decent video card.

I'm really looking forward to a new version of MadVR that works without Aero
