Descrizione

Currently, the video player in the editor just shows a black background for videos with an alpha channel. I think this is a limitation in AVPlayerView, but if anyone knows a way to make it work, let me know. According to this session from WWDC 2019, AVPlayer should support videos with alpha channel.

Here's a sample video: puppets_with_alpha_hevc.mov.zip
