  1. Hi all, hope someone here can help with the following question.

    I have 5x Multicast addresses, 1 for each of the 5 TV Networks in Sydney AU.
    I need to take 1 of the video + 1 of the audio channels and convert to RTSP output stream.
    Needs to be RTSP so it can be connected to a CCTV software.

    VLC does it, but audio and video get out of sync after several seconds.

    Is there any tools that will make this easier?





    1 of the Multicast addresses looks like this; (ffprobe result)

    Input #0, mpegts, from 'udp://@239.255.255.7:1234':
