Using VLC to retrieve Video from a NVR

[dilandau]

Hello
In my use case scenario I have a NVR that supports rtsp RFC2326 PLAY options to request stored video from a specific time.

According to the standard I would need my RTSP client (VLC) in this case to be able to request video using a format similar to the following:

C->S: PLAY rtsp://audio.example.com/twister.en RTSP/1.0
CSeq: 833
Session: 12345678
Range: smpte=0:10:20-;time=19970123T153600Z

After some searches through the forum and the internet I came to the conclusion that this option is not yet supported by the VLC player and the current support for Range: npt is very limited too.
The only time parameter the VLC player I can find is the
:start-time
which I guess it should be impacting uniquely in the npt Range value.

I just would like to ask if my conclusions are correct.
