Advanced MPC-HC Setup Guide - Page 8

I'm using this with my computer connected to a Samsung PL50C7000 tv audio is very low. On ffdshow I had the option to select 2 channels so the volume was good but i don't see this option on lav audio.

Any suggestions?

this is not LAV audio`s job & it cannot do downmix.

YOu have to add ffdshow audio processor with your speaker configuration in external filter`s tab.

For you setup [tv speakers] using ffdshow or lav audio is meanless.
The internal MPC-HC audio codec is enough.

On a fresh windows install with no filters, codecs etc:

I successfully installed the LAV audio filters, splitter and the LAV CUVID decoder. Everything is registered and preferred and the built in decoders are disabled. I can bitstream DTS-HD, DD, etc. I also installed madvr and selected it in the Output section.

I have a minor concern, in this guide @ "Step Three: Confirmation" it circles the 2 decoders. When I press ctrl+j I see the image on the right. I'm guessing this is because I'm using LAV CUVID to decode the file before passing the data to the MADVR renderer, rather MADVR using it's modified internal FFMPEG decoders. The madvr preferences controller does show up in the system tray.

Can someone verify that this is correct? If I remove the LAV CUVID filter from the external filters, it does indeed say libav, h264....

Another completely unrelated question, but in media center using the default decoders, when switching to live TV with DD enabled, I very often get silent video for 3 seconds followed by a video decoder error. This is def DD streaming related as it does not happen if I enable volume normalisation. Is this an issue people are familiar with?

i dont know if anybody cares about that but i managed to play a H264 1080p 33Mbps .mkv file with lav video & madVR [chroma/luma] Bilinear using a AMD HD4290 iGPU.








here is sample of the video file: (download)



if the cpu is capable to decode the file , i suppose every iGPU can handle madvr.

...and yes even Bilinear without advanced luma/chroma scaling configuration, the YCbCr -->RGB conversion is better than
doing that in ffdshow using EVR.

Many people will propably say that PQ is a pretty subjective thing or that you need screenshots.
Make your own experiments and decide what you video decoder & renderer you like.

PQ is just a half of madVR. Perfect judder-free, zero frame drop/repeat video playback by madVR + ReClock is the other half, and even low quality settings madVR with ReClock may be indispensable for some people.

Does anyone know how to make madVR convert from BT.601 to BT.709 colorspace? The filters that I can previously do with MPC-HC aren't available when I use the madVR renderer.

I use the BT.601 -> BT.709 filter when I watch DVD material on my BT.709 calibrated projecter.

Cheers

IIRC, there is (or there was?) something like "BT.709" in madVR calibration settings.

I think madVR calculates the 3DLuv automatically depending on the resolution of the video, which in some cases is not always correct (e.g. HDTV xvids).

I meant in madVR settings you can set your TV as calibrated to BT.709. I can be wrong though (too lazy to check ).

would be great if there was a service out there you pay for that integrates lav/madvr into mediabrowser seamlessly (no external filter), did custom 3dlut and guarantees your system's video quality to be on-par with or very close to oppo players for blu ray/mkv playback...

When playing regular dvd files I'm seeing "mpeg-2" as the decoder instead of LAV Cuvid which I see when playing bluray/MKV. Is this normal?

LAV CUVID does not work with DVD Navigator anyway.

so what decoder are you guys using? Or does it not matter for dvd as long as madvr is the renderer? I'm looking for the best picture. I'm using MPC-HC for everything except 3D iso which uses tmt5. XMBC front end. "mpeg-2 video decoder" is the listed decoder under filter. Is this MPC-HC internal decoder?

Do I need DVD nav? I only save the main movie.

The only other problem is that when I set the desktop to 24hzFP, mpc-hc freezes and will not play. So I have it set to 60hz, I then have to manually change the resolution when playing 3D. XBMC, dvdplayer, I did not have issues. It changed the resolution and played .

ffdshow Video Decoder (libavcodec, enabling "DVD decoding"). The current madVR's refresh rate changer can't detect DVD's frame rate correctly (23.976 fps for films, 59.94 for videos), unfortunately. ReClock's VB script does not work well with madVR either.

Oh, which do you play, a DVD folder/iso or a single file (then what file extension)? DVD Navigator is necessary only for DVD folder/iso. LAV CUVID will work with a single file just fine and madVR's auto refresh rate changer should work with no problem ("madVR settings" > devices > [your display device name] > display mode > list..., where you can enter 1080p23, for example; for SD contents, you will have to add a framerate token "23p" or "59p" manually to the file name).

DVD folder using DVDfab main movie. Thanks for all your help in all the forums. It's really been a learning experience....

do you know which are madvr`s input levels?
when using lav video are the levels untouched ?
when using ffdshow + yadiff which should be the YCbCr outputs?

Thanks for a great guide. I have a question though. After I applied your guide on my computer, everytime I doubleclick the screen to switch between fullscreen and windowed mode, the video seems to loose its aspect ratio (even though I have "keep aspect ratio" and "touch window from inside" set) and fulfills the whole screen for a little while, blinks black, and changes to its original aspect ratio afterwards. Im watching older TV shows a lot with 4:3 picture and this is really annoying. I was using MPC before with different set of codecs/filters and it worked fine. Any ideas? Thanks in advance for your help.

I just want to be clear on if my system will be able to handle using LAV Video and MadVR. I have an AMD Sempron 140 CPU (2nd core unlocked and overclocked to 3.2ghz) and an AMD 6850 gpu. Cinebench gives the CPU a score of 1.8pts. This should be enough to handle it all correct? I'm currently also using LAV splitter/Audio to decode audio and Reclock is handling the autoswitch of the framerate and syncs up my audio to the video. Currently I'm using EVR-custom and it is DXVA accelerated. As a result my picture is buttery smooth.

I don't have much if any interlaced video, but I do have a good bit of 480p material, and from what I understand that's where madVR shines (in upscaling), am I correct?

MPC-HC cannot use CUVID when opening the DVD folder but it can use it when opening the .VOB file. Is there anyway around this? I have my DVD files in folder format.

Okay. I understand it takes a while to resample the image. Ill get used to. Anyway, I really miss the volume bar when in fullscreen mode, as it was in the MPC version used in CCCP. Can I get it somehow?

hey there!

maybe I got it all wrong, but i do have some questions concerning the lav filters (lav video decoder) in combination with the madVR!

1.) in the advanced setup guide (1.post) you are told to use the LAV video decoder! if i do this, i get an h264, 8bit, 4:2:0 -> YV12,8bit, 4:2:0 output (for example)

BUT

if i remove the lav video decoder from the external filters list in mpc-hc, my output says: libav, h264, 8bit, 4:2:0

DOES THAT MAKE A QUALITY DIFFERENCE???

isn't libav what i should use, because that is also the setting one should use under madVR -->settings-->processing-->decoding???


my priority is maximum possible image quality.

thank you so much!!!

So I got madvr and lavfilters running now. I can definitely see a difference. Side by side pics seem useless to see the difference. But it is there.

Is there a consensus for the best settings, like spline vs. catmull etc?
