mofeng-git e670f1ffd1 refactor: 升级依赖版本并优化构建系统 
- 升级核心依赖 (axum 0.8, tower-http 0.6, alsa 0.11 等)
- 简化交叉编译配置，切换至 Debian 11 提高兼容性
- 新增 Debian 包打包支持 (debuerreotype 模板)
- 移除独立的 mjpeg 解码器，简化视频模块
- 静态链接 libx264/libx265/libopus 到二进制

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
