Will it be possible to select DXVA for interlaced VC-1 and CUVID for H264 or MPEG-2? Now one can only select either DXVA or CUVID for everything. Bat

I don't say it often enough so for all your work! This thread has everything! I follow it every day. Sometimes it makes me laugh, sometimes I cringe at the responses some people get (justified or not ) but mostly I feel educated by reading and look forward to testing something new! Thanks Nev!

Several.
- DXVA1 doesnt allow frame copyback - DXVA1 is only for Windows XP - FFMPEG only supports DXVA2

Why would you want that? CUVID is superior.

nev, do you know if HD MPEG2 software decoding handles errors differently than DXVA decoding? I've just started testing the 1080i and 720p wtv from OTA channels (I'm in the US so ATSC) recorded in Win 7's Media Center. They play relatively well, but with LAV Video's MPEG2 I get heavy gray blocking. With ffdshow, and the MS DTV-DVD decoder however, I don't get blocking, but I get slight color (reddish-greenish) and black level shifts. I don't get either when I just switch to EVR and a full DXVA chain, it plays just perfectly like on MC itself. So I still don't know for sure what's going on here, that's why I'm asking if errors from the capture could be the culprit, and somehow DXVA has better error resilience or something like that.
If it's not as simple as that, I could upload samples if anyone is interested to confirm.

@ Andy o:
Are you using LAVSplitter? LAVvideo doesn't seem to like Microsoft's .wtv spltter (StreamBufferSource). If you use mpc-hc, block StreamBufferSource - you lose continuous live TV playback, but LAVSplitter works better for everything else, and gives you the ability to select audio streams.

Benchmark results - Signature system - Video clip requested - LAV 0.44 latest

UPDATE: According to AMD and other sources over the Net, the only way to use Frame Copy with zero penalty is through OpenCL. If you want to implement a fast DXVA Frame copy solution for ATI hardware, you have to use OVD API (OpenVideo Decode). It's like NVCUVID and Intel's MSDK in its basic principle. No other way. Sorry.

If you are running nothing but MPC-HC with LAV Filters do you only uncheck all the Transform Filters or do you uncheck all the Source Filters aswell. ?
All the guides seem to contradict each other with some even saying "Transform filters (Prefer) in 'External filters' override transform filters in 'Internal Filters' (usually). So there is no reason to disable all transform filters." |

Just exploring the latest LAV package with MPC and MadVR on XP SP2, Nvidia 8400GS with 285.58 driver.
However, with HW decoding (Nvidia CUVID) enabled in the LAV Video Decoder, 720p mkv files are incredibly pixelated and torn: if I disable HW decoding, it is smooth and unpixellated. Divx avi is fine. Doesn't change if I use EVR instead of MadVR. Is my 8400GS (the updated version, not the original) inadequate to support CUVID, or is something else wrong with my setup? |

@ Nev the latest x64 version ( "Revision 870a5b4451 dxva2: implement software fallback " ) it's just crashing (MPC-HC) while the x86 version it's not crashing (working with VC1i too ) but also has no DXVA just software

Note that MPC-HCs DXVA status display doesn't work with this decoder.

Nev: I believe everything DVR-MS is a small subset of WTV container, is it at all possible to support DVR-MS in LAV Splitter? Last edited by Mixer73; 14th January 2012 at 13:29. |

DVR-MS works just fine with LAV Splitter, its just not a option in the installer. Just block the StreamBufferSource in MPC-HC and it should just work.

Yes it is
But maybe you can do something about the "DXVA" message cause even in the MPC-HC's stats (ctrl+J) it's saying "DXVA: Not using DXVA" ! and it's very confusing especially now with all this testing
