How to specify Range Clock on RTSP stream

[ard-be]

Hi Michel,

I want to playback a video recorded by my NVR by specify a Range: Clock in absolute time. I use your webrtc-streamer to play the live from RTSP url like rtsp://192.168.1.124:554/camera2 But i search, how can i use your webrtc-streamer to play my video from an absolute date time. I found an older post on live555 about this. https://live-devel.live555.narkive.com/esUSI3qm/how-to-specify-range-in-rtspclient-that-are-not-using-npt

Do you find a solution to push the range clock information to lthe RTSP server ?

Thanks,

Hi,

This is not implement but should not be really complex to add passing an argument in the options and set the range

Hi, I have tested to replace the this->sendPlayCommand(m_session, continueAfterPLAY); By the new one, const char absStartTime = "20210316T130000Z"; const char absEndTime = "20210316T140000Z"; this->sendPlayCommand(m_session, continueAfterPLAY, absStartTime, absEndTime);

I don't have any errors but the vidéo play the live and not my playback. Do you have any idea about this ?

Thanks

Hi,

You may try with openRTSP specifying

-U <initial-absolute-seek-time> | request that the server seek to the specified absolute time (format: "YYYYMMDDTHHMMSSZ" or "YYYYMMDDTHHMMSS.<frac>Z") before streaming
-E <absolute-seek-end-time> | request that the server end streaming at the specified absolute time (format: "YYYYMMDDTHHMMSSZ" or "YYYYMMDDTHHMMSS.<frac>Z") (used only with -U<initial-absolute-seek-time>

Best Regards, Michel.

@ard-be did you find a way to do so ? I'm working on an Onvif project trying to get the edge recording from an NVR and I need to provide the 'range' header with the clock time in UTC format but I'm not able to archive that. Any help ?

@MDalprato Sorry, we didn't work on that.
