It doesn't seem that anyone has reported this, but 0.50.2 breaks DVD playback with madVR.
I have madVR set as the video renderer, and ReClock set as the audio renderer in MPC-HC. External filter list is configured as:

The only thing from that list even active for DVDs would be LAV Audio, which has only gotten very minor internal changes in the last version.
I never understood when DVD with madVR worked and when it breaks, it seems completely arbitrary to me, so i don't consider this a bug, because it probably isn't caused by any of the changes but some other random thing.

Did you manage please to test the Ivy Bridge platform with madVR and high bitrate 1080p material? Is discrete graphics not needed anymore for a HTPC? Thanks Pluto

I have no regrets. The issues I'm facing will get fixed, and when they are, this machine is going to be INSANE. In a month or two I'll add a 680 and I'll have a machine that'll last me a good number of years.

One thing at a time, the deinterlacing feature is far from completion. A new reason to add HW scaling is for downscaling 4K video when the screen is smaller it will reduce copying significantly. I believe this should also be controlled by the player and/or filter.

Committed my changes to SVN (r50).
This version is for testing/development purposes only and should not be used in production SW.

Found a little problem: LAVSplitter cannot handle sample rate changes in DV (AVI Type-1 DV) files: For example some recordings start with 32khz 12bit for the first few frames because it was some previous recording on the tape, then the audio is actually 48khz/16bit. Microsoft DV Splitter has no problem with that, but LAVSplitter won´t update the format and mess up audio. Could this please be fixed?

Hendrik,
When using LAV Video Decoder (in CUVID mode) + madVR (with madVR set to do deinterlacing), is there any advantage to selecting 'High Quality Processing' in the LAV Video Decoder configuration? |

Anyway, it only affects deinterlacing, if you have LAV set to "Weave", it won't change anything because then the renderer does the job.

If you disable HQP, madVRs or EVRs will be better. But why would you turn it off? I should just remove that option.

Yes, although CUVID only works with NVIDIA, and NVIDIA has all these settings off by default, so its your own fault for turning them on.

So, I have some interesting results in this area with the GT 540M (Maybe others can try to reproduce with other GPUs?):
Configuration 1 : LAV CUVID + Adaptive HQP Deinterlacing + Aggressive Deinterlacing madVR : Force deinterlacing if in doubt Configuration 2 : LAV CUVID + Weave (None) / HQP Turned Off + Aggressive Deinterlacing Ticked (should have no effect?) madVR : Force deinterlacing if in doubt For renethx's La Travita 1080i60 H.264 clip : GPU usage in configuration 1 goes more than 95% and plenty of dropped frames throughout. in configuration 2, stays around 85 - 92%, no dropped frames -- the render and presentation queues remain almost full all throughout. |

Its not really interesting, rather expected actually.
The first configuration will need more power because it has to download 60 full frames from the GPU, and then upload them back in madVR. The second configuration only downloads 30 frames from the GPU (and uploads those back in madVR), and the deinterlaced 60 progressive frames never leave the GPU again (its happening all inside madVR) This can cause quite a bit of extra load on memory constraint systems, like mobile GPUs. Even the second case is already running very close to capacity.

nev I have a question: Pure DXVA costs less GPU performance compared to those cb/qs etc. because it needn't do a copy-back step, but how to explain the same result about cpu usage(naitve < cb/qs)? |

When you copy from GPU to CPU, and then back from CPU to GPU, obviously the CPU also has to do some work.
