I'm working on a project where I'm using Metal to draw an overlay on top of live video. After getting everything up and running I'm running into issues with the output. Please see linked video for an example. This is just with drawing the CMSamplebuffer into a Metal Texture and then back into a CVPixelbuffer and writing to file. Very new to Metal in general and having a hard time narrowing down where the problem lies. As for process, I'm rendering the sample buffer into an offscreen texture using drawPrimitives of a MTLCommandEncoder. Happy to provide more information as need. https://youtu.be/I9ZLxuZDyS8

So I'm digging through the Apple Music API trying to implement it into a music app. I feel like I have to be missing a huge piece of the puzzle. Did Apple really miss something this big?Let's take Apple Curators for instance, catalog/{storefront}/apple-curators/{id} Where do I get the list of all available Apple Curators? Same can be said for stations, artists, curators and activities. catalog/{storefront}/search looked promising for a second, until you realize you're required to supply a search term.At first glance, Top Chart Genres catalog/{storefront}/genres looked promising. Returns a full list of available Genres, but you then take one of those items and hit catalog/{storefront}/genres/{id} with it and you end up with the same exact json. Huh? Shouldn't that return me a list of albums and songs from that genre or at the very least, a link to get that information?Thus far the only thing that seems to return anything useful is /me/recent/played and /me/recommendations. /me/history/heavy-rotation is returning an empty data set, but I assume that's due to my lack of use of Apple Music (signed up a few weeks ago).Someone, please, tell me what I'm missing here. Is the API this lacking in functionality?
