    avformat/rt*p: Joining a SSM multicast group using an SDP (Issue #2171) · 7203dbde
    Ed Torbett authored
    Passes Source-Specific Multicast parameters read from an sdp file through to the UDP socket code,
    allowing source-specific multicast streams to be correctly received. As an integral part of this
    change, additional checking (currently only enabled in the case of SSM streams, but probably
    useful in similar scenarios) has been added to the RTP protocol handler to distinguish UDP packets
    arriving from multiple sources to the same port and process only the expected packets
    (those transmitted from the expected UDP source address). This resolves an issue identified
    when multiple instances of FFmpeg subscribe to different Source-Specific Multicast streams
    but with each sharing the same destination port.
