SK-TDA4VM: Can not connect to camera use RTSP protocol

Part Number: SK-TDA4VM

Dear experts,

I have a camera IP with the RTSP protocol (Reolink E1 Pro).

It can be streaming video using VLC player with the URL:


However, I cannot run a demo example, with RTSP.

   ./ ../configs/rtsp_src_example.yaml

The example does not work.

( I replace the default URL with the camera's URL).

  • Hi Kevin,

    Could you share the logs from running the demo?

    Also, in the comments in rtsp_src_example.yaml, there is an example for how to create a RTSP streamer. Are you able to reference that to create a RTSP stream?



  • Hi,

    I use the camera Reolink E1 Pro:

    This is a camera support RTSP stream so I do not need to create an RTSP streamer on Linux.

    URL: rtsp://admin:password@

    I tested it by VLC, and it works.

    When I run the example

    ./ ../configs/rtsp_src_example.yaml

    It exits and it does not work.

    The logs:

  • Hi Kevin,

    Apologies for the confusion, what I meant was for pure debugging purposes, could you manually create the RTSP streamer on Linux and run the default example included with the SDK? 

    I would like to make sure that some baseline application that is known to work can be ran on your system to verify basic functionality of the system.
