madVR wiki thread
SamuriHL:
It's not madVR that's the issue. For me, I have an Athlon X2 4200+ as one of my HTPC's. It's just not powerful enough to decode HD video (h.264 or VC-1) using a software decoder. Since madVR doesn't work with DXVA, a software decoder is needed. Your CPU is a quad core....hardly "low end" like my dual core laptop and second HTPC. ;) GPU decoding works wonders in that environment.
BryanC:
I was having some problems with my Haali->CoreAVC->madVR setup getting stuck on some sections of my x264 rips, so I decided to experiment a little. I tried using LAVSplitter instead of Haali and I could not get any movies to play. madVR would pop up a gray dialog box, but I could not tell what it was saying. Next I replaced CoreAVC with LAV CUVID and I would see one frame of the movie, but it would not play and I could not seek. I replaced LAVSplitter with Haali again and everything worked fine. So my question is:
How do I get LAVSplitter and madVR to work together nicely? It appears that I can get madVR to work with hardware accelerated decoding if I use CoreAVC or LAV CUVID but proper playback is dependent on the splitter.
Also, I've obviously used LAVSplitter as my source filter, but there is also a choice to use LAVSplitter in my decoding filters. Do I need to select it twice? What does the LAVSplitter decoder do? Is it just the non-accelerated decoder?
Thanks!

@Bryanhoop:
On my setup, I have the LAV Splitter Source set up for "Source". I have FFDshow Video Decoder, LAVAudio and Arcsoft HD Audio (DTS only) set up for other filters and, of course, madVR set up as the VidRen.
Assuming your video decoder is working properly, this should be all you need to set up (sans FFDshow), assuming your hardware is up to the task.
You might try substituting the video decoder to FFDshow (-MT under codecs for AVC) to see what happens. I assume when you say "x264 rips", you really mean x264 encodes of AVC material?
You probably already know this too, but madVR requires the video decoder to output NV12 or YV12 format.
Another test is to configure MPC-HC for the same playback graph and see what happens.
BryanC:
Mike, thanks for the input.
I don't know if it is a hardware issue but I cannot get any file to play when using LAVSplitter, regardless of decoder and renderer. Strangely, I can also not get playback using Haali, LAV CUVID and madVR if using ffdshow audio decoder or LAV audio but AC3filter works fine.
Weird stuff. Maybe I'll just wait for a few more revisions of LAVSplitter and LAV audio to give it a try.
BryanC:
Oh, and a heads up...the upcoming LAV Audio 0.25 will be able to bitstream AC3, E-AC3, TrueHD, DTS and DTS-HD.
I'm just hoping I'll be able to use it.
