We've been running a 24.x version of OBS on an iMac running 10.14.6 Mojave for the past three months, connected via USB to an iPhone 10 with 13.3.1 software, as a video source for Facebook Live streaming. To date, it has run seamlessly. Then, starting today, we noticed a HUGE video lag between the camera and the OBS view window. After 1 minute of streaming, the OBS view might be 10-15 seconds behind the iPhone screen, and eventually, as it fell even further behind, the video became unstable on Facebook, and we had repeated Facebook drops. I updated to OBS 25.0.8, and the problem persists. I tried upping the bit rate on the OBS iPhone client to no effect. I have log files from our repeated tries today. Any ideas?
