When using VideoPlayer in SwiftUI it adds a black background to the video player and I would like to make it clear. Trying to add .background() of clear does nothing. Seems like a really silly "default" style to add this black background to a video. Any suggestions on how to achieve this?
Perhaps I misunderstand your question, but the way I see it:
There is nothing „silly“ about this behaviour, because the "background" is part of and encoded into the video. Is there even a standard for "transparent video“? How should the video player know which part of the video you consider "background".
If you meant to remove the "black bars" of letterboxed widescreen videos they may also be part of the video or if not, make sure you size the video player to the correct aspect ratio to prevent it from padding your video. (I have not tested this).
