It's a FFmpeg 4 compatibility issue occurred after bindgen update, type of AVFrameSideData::size changed between FFmpeg 4 and 5. https://github.com/FFmpeg/FFmpeg/blob/release/4.0/libavutil/frame.h#L180 https://github.com/FFmpeg/FFmpeg/blob/release/5.0/libavutil/frame.h#L223

Let me fix it.

@prateekmedia Should be fixed by https://github.com/larksuite/rsmpeg/pull/111 Please try rsmpeg = { version = "0.14.1", features = ["link_system_ffmpeg"] }

Thanks for the quick fix @ldm0
