Low Frame Rate / Slow RTSP Video through stock QGC

I’m feeding video into the herelink 1.1 air unit through the ethernet port, attempting to use RTSP to stream video from my flight controller (VOXL 2). I’m able to get UDP connection to the Herelink through QGC and the video up over RTSP. However, the RTSP video is extremely low frame rate, roughly 1 frame every 5 seconds. Please let me know any screenshots/logs or anything else that you need to help troubleshoot.

Interestingly enough, using the SIYIQgroundcontrol application solves the issue, and allows me to feed RTSP video in extremely low latency and at high quality. This is an imperfect solution for seperate reasons.
