Lav video dxva2 native vs copy back

MediaPortal 1. After clicking on the screwdriver icon next to the LAV Video Decoder, you'll be presented with the following settings screen:. DXVA implementations come in two variants: native and copy-back. Almost all implementations are of the native type. The LAV video decoder that is included in the pack offers both variants. With the native type, the decoded video stays in GPU memory until it has been displayed. This brings some limitations with regard to playback. The DXVA decoder must be connected directly to the video renderer. There can be no processing filter in between. The video renderer must also support DXVA, which give you a bit less freedom of choice in renderers. The reason for keeping the decoded video inside GPU memory is efficiency. They are too slow for smooth playback.

Though it is taking place in every part of the System not only Video and 3D also Web Browsing HTML5 benefits these days i left this out in the Demo though due to limited Space And for many things these days in Video you wont need Pre Rendered Processing anymore because you can do it efficiently in "Realtime" and it evolves constantly so to lav video dxva2 native vs copy back the same result on another system you wont need to render it out all just share your edit script embed them as metadata you fixed everything with and their you go no no need to waste hours on rendering anymore but instant results that are changeable at anytime as you wish maximum flexibility, lav video dxva2 native vs copy back.

I would assume that "copy back" means that the decompressed frames are copied back to main memory after they have been decompressed by the graphic card's hardware decoder.

CUVID forces the graphics card into its highest performance state. One of the reasons to use hardware accelerated decoding is to reduce power consumption. With a high powered graphics card such as my GTX , most of that benefit is lost.

I think it might be my next display, though it is really expensive. Here's what I use for my TI for upscaling settings. The graph building has never used GPU information before, so this change does require creating a Direct3d device, asking it a few questions, and releasing it. Theoretically there should be no difference whether TV is receiving 24 or but in reality there might be some small differences depending on the video processor or the way the panel is being driven when at higher refresh rates. My understanding is that the author madshi is busy working on another project and probably won't be taking feature requests. If you are seeing dropped and repeated frames, it sounds like your madVR settings are too demanding for the card. Log in. It's encouraging to hear that people are actually noticing reduced GPU load and temperatures from this change. Insert Quotes Quotes Post Reply. No, I dont have the TV, still waiting for some new model to check the improvement if any. I should probably write a tutorial. May 26, Do you have references you can site about the gtx s 10 bit support? I haven't done extensive testing of this though.

Our decoding and rendering benchmarks consists of standardized test clips varying codecs, resolutions and frame rates being played back through MPC-HC. The former provides hints on whether frame drops could occur, while the latter is an indicator of the efficiency of the platform for the most common HTPC task - video playback. The Enhanced Video Renderer is the default renderer made available by Windows 8.

Also i went for copyback manual selection, since there is a possibility i might add some devices to PC which are a Hardware video decoder, but i dont want them to be used. Ideally you would want both modes available as some content is 24 and most is Page tree. Glad to have finally managed to solve this pet peeve of mine. Hi guys. Originally Posted by EpsilonX.
