  • Hardware Accelerated H264 Decode using DirectX11 in Unity Plugin for UWP

    8 janvier 2019, par rohit n

    I’ve built an Unity plugin for my UWP app which converts raw h264 packets to RGB data and renders it to a texture. I’ve used FFMPEG to do this and it works fine.

    int framefinished = avcodec_send_packet(m_pCodecCtx, &packet);
    
framefinished = avcodec_receive_frame(m_pCodecCtx, m_pFrame);
    
// YUV to RGB conversion and render to texture after this

    Now, I’m trying to shift to hardware based decoding using DirectX11 DXVA2.0.

    Using this : https://docs.microsoft.com/en-us/windows/desktop/medfound/supporting-direct3d-11-video-decoding-in-media-foundation

    I was able to create a decoder(ID3D11VideoDecoder) but I don’t know how to supply it the raw H264 packets and get the YUV or NV12 data as output.
    (Or if its possible to render the output directly to the texture since I can get the ID3D11Texture2D pointer)

    so my question is, How do you send the raw h264 packets to this decoder and get the output from it ?

    Also, this is for real time operation so I’m trying to achieve minimal latency.

    Thanks in advance !

    I have downloaded FFMPEG source code(c code) by the following link

    http://ffmpeg.zeranoe.com/builds/

    After that,I have completed the configuration part then i was generated and linked the library files *[avcodec-54.lib,avdevice-54.lib,avfilter-3.lib,avformat-54.lib,avutil-52.lib,swresample-0.lib,swscale-2.lib ]*on Microsoft Visual Studio C++ by creating a new project by including all .c and header files.
