normal Streaming mode:
normal => Full FPS all the time.
adaptive => Default send only I-frame for MP4 and
H.264, and send 1 FPS for MJPEG. If DI or motion window

for 10 seconds.
(*Note: this parameter also works on non-timeshift
streams.)
reftime mm:ss The time
camera receives
the request.
Reference time for maxsft and minsft.
(This provides more precise time control to eliminate the
inaccuracy due to network latency.)
Ex: Request the streaming from 12:20
rtsp://10.0.0.1/live.sdp?maxsft=10&reftime=12:30
forcechk N/A N/A Check if the requested stream enables timeshift, feature

least.
