LAV Filters 0.71
Code:
General - LAV Filters now requires Windows Vista or newer, Windows XP is no longer supported LAV Splitter - NEW: Preliminary support for UHD Blu-ray parsing LAV Video - NEW: D3D11 hardware accelerated decoding (native mode with madVR, Copy-Back otherwise) - Fixed: HDR metadata was not properly communicated to madVR in DXVA2-Native mode - Fixed: Anamorphic WMV9/VC-1 videos were not being played back with the correct aspect ratio in all cases - Fixed: Changing certain settings while playback was paused could result in a deadlock - Fixed: Playing severly corrupted HEVC streams with hardware decoding could result in playback failing entirely, instead of skipping over the corruption LAV Audio - NEW: Basic support for AAC 960 streams (common in DVB radio streams) Its been long overdue to release this, so I can start working on some new things without breaking the release! D3D11 Decoding The main motivation behind offering D3D11 decoding is the ability to be able to process the resulting image on the GPU without any loss - something that was not always possible on DXVA2. To be able to actually leverage this, you'll need a renderer which also supports D3D11 input from a decoder - currently this is only madVR. This allows full performance on-GPU decoding and processing without any quality loss. D3D11 also offers a Copy-Back mode, however it should probably be quite similar in performance then DXVA2. Note that the way you select Native/Copy-Back for D3D11 is different than DXVA2. D3D11 will use Native-mode when its set to "Automatic" device choice, and the renderer supports Native mode. If you select a specific device, that forces Copy-Back mode (because for Native to work, the renderer basically selects the device). There are still a few limitations on using D3D11-Native with madVR, most notably deinterlacing is not supported yet. This is a feature madVR will have to implement in the future.

Thanks for the update!
Native D3D11 caused a 'driver stopped responding' error for me. Using a R9 270X and the 18.2.2 drivers released 2 days ago. I assume this is a driver issue? I also didn't change any settings in madVR or disable deinterlacing. D3D11 CB mode works fine and the load looks similar to DXVA2. |

Just as "anchor":
Officially, the last stable release supporting XP was v0.70.2... There was a link to Aleksoid1978's diff to 0.70.2.1 with experimental CUVID H.265 10-bit decoding. And clsid published MPC-HC 1.7.13.1 incl. a patched LAV Filters 0.70.2.3. From there, the thread kept derailing over and over. |

madVR doesn't support D3D11 deinterlacing yet, it's in the release notes.

With any other renderer you would get the same deinterlacing as you would with any other decoder. Its not performed by LAV.

And native D3D11 works if you go back to 0.71.0 (stable)?

I would expect more things to be broken in the current nightly. Unless you have a reason to, one really shouldn't use in-development versions on a daily basis.

Two questions:
1) Is there a reason 0.71 isn't listed in the first post of this thread? 2) Does D3D11 mode support deinterlacing yet? Thanks.
