  • How to transfer video as rtp stream with least delay by FFmpeg

    2 décembre 2020, par Yasushi2019

    I use AXIS M1045-LW supporting rtsp/http access, and my Windows 10 PC can access to the camera through LAN.

    


    I would like to transfer the video as rtp with keeping H.264 codec which is supported by the camera.

    


    


    Image

    


    [Camera] == (rtsp or http) ==> [FFmpeg on Win10] == (rtp) ==>

    


    


    When I accessed the camera through Google Chrome on my Win10 PC, there is only 1 or 2 sec delay.

    


    However, when I tried access by the following command, I found over 10 sec delay.

    


    How could I reduce the delay as much as possible ?
