• Any experts on CCTV DVRs here?

    I have 8 analogue cameras connected to a Samsung DVR.

    I also have viewer software on a computer that connects to the DVR over ethernet and also my mobile phone can do the same. They can both access
    live video streams as network streams

    Now I would like to do the same with VLC.

    According to Samsung, the DVR can present RTSP streams using a
    correctedly formatted requesting HTTPS URL that contains the IP address
    of the DVR, the stream number from 0 to 7, the username and password in
    plain text.

    Trying this with VLC simply does not work.

    I am trying to do this as:

    Click on Media menu

    Open Network Stream or CTRL N

    rtsp://admin:NNNNNNN@192.168.0.234:10010/0

    admin is the name of the account holder and NNNNNNN is the password (not literally but replaces the true password for the purposes of this post.

    I get the following:

    Connection failed:
    VLC could not connect to "192.168.0.234:10010".
    Your inpConnection failed:
    VLC could not connect to "192.168.0.234:10010".
    Your input can't be opened:
    VLC is unable to open the MRL
    'rtsp://admin:NNNNNN@192.168.0.234:10010/0'. Check the log for details.


    I can use a web browser or the Samsung Viewing app and I can confirm the
    IP address, username and password all work.

    I have even tried to view the HTML code for the web viewer to see if the
    code could give me a clue but no joy there.

    Do the cameras/dvr claim to be ONVIF compatible? There is software to
    try to find the correct rtsp:// URL, e.g.

    <https://help.angelcam.com/en/articles/372646-how-to-find-an-rtsp-address-for-an-onvif-compatible-camera-nvr-dvr>

    I certainly got VLC to talk to some generic AliExpress cameras

    Can you use wireshark to sniff the communication between you cameras and
    dvr?

    scrap the above query....

    the correct format to use is:

    rtsp://admin:PASSWORD@192.168.0.234:558/LiveChannel/0/media.smp

    Now how do I find out the resolution of the RTSP stream?

    right I have compared the RTSP stream side by side with the Veiwing
    software. The latter is reporting 5 MP and its clear the RTSP stream is
    of much lower resolution in VLC.....

    Main will likely be 1920x1080 or 1280x720, sub could be 544x576 maybe
    lower, if yu get VLC it'll tell you in the tools/media tab.

    just found it in VLC

    VLC is reporting 640 x 386 awith a frame rate of 29.97 Hz. (!)

    Ideally I'd like tyo get this up to 1920 x 1080.

    The idea being I could then set up 8 Raspberry Pis all using VLC to view
    one camera each via RTSP in full screen and then feed the HDMI output of
    the 8 Pis into a bank of 8 DVB-T modulators so I can have 8 in-house DTT channels. So we can go to any TV set in the house (I have 8!) with a
    remote control and we can see whats on the cameras without the faff of
    going to a PC, starting it up, launching teh viewer software etc or
    mobile phone with its small screen

    The HDMI output of the DVR is currently feeding a HDMI mod and is the
    mosaic of all 8 cams. Currently the resolution on this is 1920 x 1080.

    just experiment with other stream numbers 0,1,2,3 in the URL, tell
    google what make model camera you have and Gemini will give you example
    URLs too try ... you're not going to break anything trying,

    yes, but the cameras are analog, so the RTSP stream is actually being generated by the DVR.

    I have tried stream0, stream1, stream2 and stream4 and RecordingChannel
    but the only one that works so far is LiveChannel at the resolution of
    640 x 386

    If they are baseband analog (composite video) the actual resolution will
    not be anywhere near 1920x1080, even is the sensor is "5MP".

    They are outputting TVI at 5.0 MP.

    The cameras can output in AHD, CVI or TVI at up to 5.0 MP and 960H if
    put into CVBS mode.

    The DVR viewing software shows the recordings as being at 5.0 MP

    So there is clearly a 5.0 MP stream to be had somewhere....
