dx11_video_player

Forked from yabadabu/dx11_video_texture; You can use this sample code to render mp4 files base D3D11 VideoProcessor; Caution! Using nv12 format to render 1080p video has issues, need to fix.

Usage

Choose input file

In app.cpp file to set the input video, now it's CPU decode method

VideoTexture::createAPI();
if (!video.create("data/1080p.mp4"))
  return false;

Set output format

In video_texture.cpp open function, you can set output type to nv12 or other

//CHECK_HR(pVideoReaderAttributes->SetGUID(MF_MT_SUBTYPE, MFVideoFormat_IYUV),
//  "Failed to set media sub type on source reader output media type.");

CHECK_HR(pVideoReaderAttributes->SetGUID(MF_MT_SUBTYPE, MFVideoFormat_NV12),
         "Failed to set media sub type on source reader output media type.");
//CHECK_HR(pReaderOutputType->SetGUID(MF_MT_SUBTYPE, MFVideoFormat_IYUV), "Failed to set media sub type on source reader output media type.");
CHECK_HR(pReaderOutputType->SetGUID(MF_MT_SUBTYPE, MFVideoFormat_NV12), "Failed to set media sub type on source reader output media type.");

Create correct texture

Texture format depends on your video output type, in video_texture.cpp update function, you can choose one texture create method and update method;

//if (!target_texture->create(width, texture_height, DXGI_FORMAT_R8_UNORM, true))
//if (!target_texture->CreateTexture(width, height, DXGI_FORMAT_420_OPAQUE))
if (!target_texture->CreateNV12Texture(width, height))
{
    return;
}

//target_texture->updateFromIYUV(byteBuffer, buffCurrLen);
//target_texture->updateYV12(byteBuffer, buffCurrLen);
//target_texture->updateBGRA(byteBuffer, buffCurrLen);
target_texture->updateNV12(byteBuffer, buffCurrLen);

I recommend you to choose NV12 format, but for now it has issue with 1080p video render, if you have any idea about it, please make an issue

Here is the 1080p render result:
