PARAMETER VALUE
DEFAULT
DESCRIPTION
maxsft <positive
integer>
0
Request cached stream at most how many seconds
ago.
The value must be a positive integer. (>0)
tsmode normal,
adaptive
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 are triggered, the streaming is changed to
send full FPS for 10 seconds.
(*Note: this parameter also works on non-timeshift
streams.)
tsmode
must exactly match well-defined wording
(normal, adaptive), unknown parameters are always
ignored.
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

Check if the requested stream enables timeshift,
feature and if minsft is achievable.
If false, return “415 Unsupported Media Type”.
