There's a NextLevel video capture library in Swift called "NextLevel".
According to NextLevel's description, https://github.com/NextLevel/NextLevel,
it supports Custom Buffer Rendering.
But I'd like to know it's supported for slow motion mode. So far, I was trying to use it without luck. It worked for normal recording, but not for slow motion.
Am I missing something?
My goal is adding a logo/watermark to the recorded video.
Any help would be much appreciated.
