We are working on integration between NX and ISCS control command platform. Requesting Nx Developer/R&D team to assist on the follow-up queries
Regarding the video stream parameters/play/Ptz option/License,
1. Is the HTTP playback streaming suppose to show the current running time and streaming info of the Live/Playback archive stream by default? If yes, what is the parameter flag to enable this timestamp option?
2. What does the HTTP stream flag below show? How does it affect the streaming?
sfd Stand Frame Duration If the parameter is present, video speed is limited by real time.
- For activating Recording mode, besides using Nx Witness application Camera settings - Recording event rules schedule to activate this mode, are there other direct methods to activate the Recording of camera option? Will the left circle status show this recording flag?
-
How is the HTTP stream flag below added?
signature Add signature to exported media data, only mp4 and webm formats are supported
- The Rewind/Fast Forwardbutton from -16X up to 16X is available on the Nx Witness application. Is it available on the Webadmin page or API in future? Or currently it is only available on the Witness app?

FastForward

For the PTZ offset run control from Nx Witness application API, will the camera position return to the tart position after every PTZ move using /api/ptz?cameraId=<Cameraid>&ActivatePresetPtzCommand is called or will it be the end of the last PTZ sequence saved position run?
- License validity is expiring in a week's time, will you be able to renew further?
Thanks.

Hello,
1. Is the HTTP playback streaming supposed to show the current running time and streaming info of the Live/Playback archive stream by default? If yes, what is the parameter flag to enable this timestamp option?
Could you please elaborate on what do you mean by "current running time"? "Streaming info", what info specifically do you mean?
Regarding 2.
The answer given is the correct one.
Regarding 3.
In addition to already written, almost all the configuration activities the Nx WIntess application is capable of, can be performed via the Server API, just because the Nx Witness application uses the same API.
How to activate recording on a camera via API was explained in this post

I'll try to rephrase it.
There is no Rewind/Fast Forward neither - 8X, 16X, 32X capabilities in the Server API.
As it was mentioned above, the Nx Wintess application uses the same and only Server API described in the API documentation in the Server web interface.
The Rewind/Fast Forward 8X, 16X, 32X functionality is implemented in the application, not in the Server API.
Your application requests a video stream from the Server via media API, the Server will feed the stream in the "best effort" mode, that means as fast as it can, which could be 8X, 16X, 32X or 64X or more of the live video stream, depends on the HWS and network performance. It up to the application to cache the stream data and display the stream according to the Rewind/Fast Forward buttons pressed in a player.
