Ha! So happy I'm not the only one I feel a fever coming on that day I'm afraid I'll have to miss work

The beta has me all revved up; I can't wait to get past Level 14 and see some new stuff!!

Anyone have a recommendation for minimum CPU/GPU for MPC-HC/madVR/LAV.

I currently am getting about 300 frame drops during a typical BD movie ripped to .mkv with a 23.976fps/bitrate of about 32mbps. I also get a huge number of frame drops playing back a 59fps 720p .mkv. I seem to get fewer frame drops using no HW decoding compared to DXVA Copyback or DXVA Native. I would have expected the reverse.

I currently have a E4200 2.2Ghz/ATI 5570. Is it time for an HTPC upgrade?

I have this one:

http://www.asus.com/Graphics_Cards/N...0_DC_SLDI1GD3/

No fan. I also use it with a passively cooled Intel Core i3 2120T. Couldn't be more happy, it has played back everything I have thrown at it without problems.

Are you using CUVID with LAV with this card or relying on the CPU to decode the video?

I have some questions about the configuration settings of my JVC RS45 projector with LAV filters+MPC-HC.

1. HDMI Input
I can select a. Standard (16-235), b. Enhanced (0-255) or c. Super White (16-255) in the JVC RS45 projector menu.
What is the setting that should be used when using a HTPC with:
- Blu-Ray content to play
- Media Player Classic Home Cinema
- madVR as output renderer (set to PC levels 0-255 as RGB output levels)
- LAV video filter (RGB set to 'untouched' in LAV video filter)
- NVIDIA GTX460 with default 1080p23 profile BUT with n vidia fix during installation (for further information about this fix check http://forums.nvidia.com/index.php?s...post&p=1328716)

2. Color Space
I can select YCbCr (4:4:4), YCbCr (4:2:2) or RGB. It seems that only RGB seems to show the correct colours. I thought Blu-Ray specification was 4:2:2?

Hi,

I put together a small test version.
I remember someone asking about speex support, and because i put together a cross-compiling environment today, i thought i would just build the speex library and see if it worked.

x86: http://files.1f0.de/lavf/LAVFilters-...3-g0e154c3.zip
x64: http://files.1f0.de/lavf/LAVFilters-...e154c3-x64.zip

Other then speex, nothing interesting since 0.50.2

If you can, please try speex decoding. I only had one sample, but that one worked.
Note that most likely only LAV Splitter + LAV Audio will work. If you can provide me with files that contain speex, and an info which other splitter properly outputs it, i can maybe make it work with that as well.

Yes, CUVID exclusively. I've configured my screen for pure 23,976 for all progressive material.

For interlaced 29,970 and 25,000 I use 59,940 and 50,000, respectively. Works like a charm with the hardware deinterlacer provided by CUVID.

Thank you, I could reproduce the bug with mplayer2 too.
I submitted the bug here.

LAV Audio decoder does not work with system AVI splitter.

It doesn't have one. It only has support for libspeex, which i use now.

madVR should output RGB to your projector, that could explain why only RGB looks right.
Most BD videos are still 4:2:0 but it doesn't matter since it gets converted to RGB anyway.

nevcairiel, been looking at this VC1 thing for the bd source filter. Looking at LAV, it looks like you are only using an allocator of 256000 bytes or 0.25~ meg for VC1. If for VC1 entire frames have to be sent to the decoder, does that mean it might just die if frames are over that size? I can see key frames maybe being larger .. ? Unless I am missing some critical piece of understanding.

You are.
There is no fixed packet size, the allocator just has some dummy value set, but since the source filter controls the allocator, it'll just have the packets matching the frame size perfectly, no extra allocation is done. Every packet has a different size.

For no VBR format you can use a static packet size, unless you specify it to be way huge, which isn't a good idea. However you have to tell the allocator some value in that allocator properties structure, could as well be "1" or something.
Most other splitters use a static size, and just increase that static size once a frame exceeds it. I used to do that as well, but implemented a better method recently.

Out of interest I've run lavfilters sources through CppCheck and found these warnings:

decoder/LAVAudio/Media.cpp:274
incorrectLogicOperator : style : Expression always evaluates to false. Did you intend to use || instead?
Code:
  if (num_channels < 1 && num_channels > 8)
    return 0;
demuxer/LAVSplitter/PacketAllocator.cpp:36
duplicateBreak : style : The second of the two statements can never be executed, and so should be removed

Code:
    return GetInterface((ILAVMediaSample *) this, ppv);
    return S_OK;
demuxer/Demuxers/LAVFDemuxer.cpp:74
uninitVar : style : Member variable 'CLAVFDemuxer::m_pBluRay' is not initialized in the constructor.

And some other "not initialized in the constructor" warnings, which are too many to describe here.

There were other minor things like assignments to a variable that is never used, like ret in CBDDemuxer::Open(), but that's not that important.

Hope it helps!

Maybe use static code chekers sometimes?
