Thanks! It works! FPS imrpoved from 6fps/s to 36fps/s!

Thanks very much for your reply! But my usecase is a bit different. I'm building a real time VR180 minitoring app, so I will process the video frame by frame to reduce latency. Currently I use STMAP to convert fisheye image to equirectangular format, and render it into a half sphere. AVPlayer way is great, but I won't use AVPlayer... Anyway thanks very much for your reply!

Thanks! It's working now! I have tried the same thing 1 month back and at that time it's not working, must be fixed recently! Ther is another issue comes with Vision OS 26.1, in 26.0.1 I can get 4k resolution options with UVC input, but after upgrade to 26.1, same capture card only supports 1080p..

My app uses UVC input, for 26.0.1 it can supports 4k, but 26.1 only supports 1080p
