Rendering of the control runs even on Visual Studio Designer so you can see live changes that have been performed.</p> <p>The Media Player has been developed in C# from scratch to reach best performance and low resource consumption. It is based on FFmpeg multimedia framework (Decoding hardware acceleration &amp; threading) and performs Direct3D / Direct2D / DirectWrite interops based on SharpDX for Video &amp; Text Rendering and does Hardware Acceleration (VideoProcessorBlt &amp; PixelShaders).</p> <p><a href="https://github.com/SuRGeoNix/Flyleaf">https://github.com/SuRGeoNix/Flyleaf</a></p> csharp dotnet showdev github John Stamatakis Thu, 04 Jun 2020 14:22:20 +0000 https://dev.to/surgeonix/how-to-perform-hardware-gpu-video-acceleration-in-net-based-on-ffmpeg-sharpdx-5d5p https://dev.to/surgeonix/how-to-perform-hardware-gpu-video-acceleration-in-net-based-on-ffmpeg-sharpdx-5d5p <p>As I've not found any similar resources / documentation I've decided to write my own tutorial / project for how to perform Hardware (GPU) Video Acceleration without using CPU or even RAM at all (focusing on Windows platforms and DirectX).</p> <p>I've been using on my Video Player project FFmpeg 's Hardware Acceleration for decoding already, but that was not the heavy part for CPU/RAM as the Video Processing is (converting NV12 texture2D to RGBA - I was doing that with ffmpeg 's sws_scale).</p> <p>After straggling by reading few resources and large low level code I've managed to perform it by grabbing ID3D11Texture2D from ffmpeg's decoder and transfer it to mine ID3D11Device (with the help of SharpDX).</p> <p>Finally, as I had access to that texture in GPU i called DirectX VideoProcessorBlt to convert it without bringing it back in CPU.</p> <p>You will be able to find a Sample .NET CSharp Project and more details at my github -&gt; <a href="https://github.com/SuRGeoNix/MediaRouter/tree/master/Tutorials/VideoPlayer_HWAcceleration">https://github.com/SuRGeoNix/MediaRouter/tree/master/Tutorials/VideoPlayer_HWAcceleration</a> </p> csharp dotnet showdev tutorial John Stamatakis Tue, 26 May 2020 04:35:00 +0000 https://dev.to/surgeonix/partytime-v1-2-video-player-torrent-streamer-based-on-ffmpeg-2nk7 https://dev.to/surgeonix/partytime-v1-2-video-player-torrent-streamer-based-on-ffmpeg-2nk7 <p>The new release (v1.2) is out, supporting more formats and Torrent streaming with much better performance. I would be interested how it does (performance wise) in comparison with other players. Please have a try and let me know!</p> <p>Download: <a href="https://github.com/SuRGeoNix/MediaRouter/releases/download/v1.2/PartyTime_v1.2_x64.7z">https://github.com/SuRGeoNix/MediaRouter/releases/download/v1.2/PartyTime_v1.2_x64.7z</a></p> <p>Github: <a href="https://github.com/SuRGeoNix/MediaRouter">https://github.com/SuRGeoNix/MediaRouter</a></p> csharp dotnet showdev github
