mofeng-git 01e01430da feat: 支持 MJPEG 解码与 MSD 目录配置
- FFmpeg/hwcodec 增加 RKMPP MJPEG 解码与 RAM FFI,ARM 构建启用对应解码器
  - 共享视频管线新增 MJPEG 解码路径(RKMPP/TurboJPEG),优化 WebRTC 发送与 MJPEG 去重
  - MSD 配置改为 msd_dir 并自动创建子目录,接口与前端设置同步更新
  - 更新包依赖与版本号

A real-time hardware codec library for RustDesk based on FFmpeg

Codec

Windows

GPU FFmpeg ram FFmpeg vram sdk vram
intel encode qsv qsv Y
intel decode d3d11 d3d11 Y
nvidia encode nvenc(nv12->d3d11) nvenc(d3d11) Y
nvidia decode d3d11 d3d11 N
amd encode amf amf Y
amd decode d3d11 d3d11 Y

Notes

  • The reason for discarding the codecs using Cucontext is discussed in the following forum thread: https://forums.developer.nvidia.com/t/cuctxdestroy-causing-system-freeze-and-black-screen/290542/1. Based on the information above, there are several optimizations and changes made to the codec:

    • FFmpeg encoding AV_PIX_FMT_NV12 directly: The codec is modified to transfer AV_PIX_FMT_NV12 to AV_PIX_FMT_D3D11. This is done because FFmpeg doesn't use Cucontext if the device type is AV_HWDEVICE_TYPE_D3D11VA.
    • FFmpeg decoding with AV_HWDEVICE_TYPE_CUDA acceleration: This functionality is disabled and replaced with AV_HWDEVICE_TYPE_D3D11VA. The decoding process now utilizes D3D11VA acceleration instead of CUDA.
    • SDK decoding with CUDA acceleration: The CUDA acceleration support is disabled.
  • amd sdk remove h265 support, https://github.com/GPUOpen-LibrariesAndSDKs/AMF/issues/432
