Revive: dumping/ffmpeg_backend: Various fixes (#6528)
* dumping/ffmpeg_backend: Add FPS filter So that the recorded video can be at 60FPS (which is supported by most encoders) while still maintaining correct speed. * dumping/ffmpeg_backend: Add HW context support Required for some HW acceled encoders. Not tested as my devices don't seem to require this. * CMake: Copy avfilter dll for MSVC * CMakeLists: Require FFmpeg 4.0 * ffmpeg: Fix dumper compile error on MSVC. * ffmpeg: Address review comments. --------- Co-authored-by: zhupengfei <zhupf321@gmail.com>
