ffmpeg is now running natively on AROS on my Mac. The clip here is a 2784x1888 h264 at 60fps, and it decodes and plays at full speed in a little viewer I built. All native ARM code, running ffmpeg's real aarch64 NEON assembly (not the C fallback), no transcoding, no host tricks. The text on top (frame, size, codec, fps) is drawn by the player itself, so what you see is really what's running. Cheers to @Kalamatee. A lot of the recent stdc/posixc code in AROS is his and ffmpeg sits right on top of it. PS: the mouse cursor you see moving is in the recording itself, and this video shows my reverse engineering WIP version of Moonstone to C#🗡️
