Reverse video playback on MacOS and iOS

[tannker]

Does fvp / mdk-sdk support reverse playing video on MacOS and iOS?

With flutter video_player package I have discovered that for some videos (e.g. HEIC MOV) reverse playing is working, if I modify plugin code and allow negative playback speed. I guess this is due to fact that Apple's AVPlayer generally supports reverse playback if its canPlayReverse property returns true for a specific video file.
Reverse playback is also working on QuickTime player on Mac.

I have tried to alter also fvp code in order to support negative playback speed, but currently have not succeeded - it always seems to default to 1.0 in such case. Maybe there is some additional check on mdk-sdk C++ side or it just does not support it at all.

Hence the question - does fvp / mdk-sdk theoretically support reverse playing video (e.g. HEIC MOV that reverse plays with AVPlayer) on MacOS and iOS?
