Has anybody successfully used AVCaptionRenderer for anything?
I am attempting to preview what AVMutableCaptions will look like by using AVCaptionRenderer. I am able to render an image with the caption (very small in the lower left corner), but changes to text properties are not having any effect.
I have tried the following:
setBackgroundColor - No effect.
setFontStyle - No Effect.
textAlignment - No effect.
I'm beginning to think that AVCaptionRender isn't what I think it's for. The documentation is sparse, the mention in the WWDC video is brief, and I can't find any sample code.
The video mentions reaching out here for help adopting these APIs, so here I am.
