fps from rtsp doesn't seem to match camera setting on Trackmix LTE

[AlexH-BoxFish]

Describe the bug
When the camera fluent/clear stream is set to 15FPS I can read from the rtsp with ffmpeg at 1x speed, and the stream information looks correct:

Stream #0:0: Video: h264 (High), yuv420p(progressive), 896x512, q=2-31, 15 fps, 15 tbr, 90k tbn

If I re-configure the stream in the reolink app to be 12fps or 10fps then restart everything I see the same stream information:

Stream #0:0: Video: h264 (High), yuv420p(progressive), 896x512, q=2-31, 15 fps, 15 tbr, 90k tbn

and on 10fps the same ffmpeg command will not go above 0.6x~ processing speed. This leads to ffmpeg missing footage and the timestamps being incorrect.

To Reproduce

1. Lower camera fps
2. Run ffmpeg:

ffmpeg -rtsp_transport tcp -re -timeout 10000000 -i rtsp://127.0.0.1:8554/trackmix-test-1/Sub -vcodec copy -an -f segment -hide_banner -segment_time 0:01:00
-strftime 1 -use_wallclock_as_timestamps 1 -reset_timestamps 1 -movflags frag_keyframe+empty_moov -segment_format mp4 test/%Y-%m-%d/%H.%M.%S.mp4

Expected behavior
Stream FPS changes to match camera setting.
