[FFmpeg-user] RTP Multicast doesn't play

[Eric Lovelace]

Hello all,

I am attempting to take an rtmp stream and push it out over multicast.  It appears like it is working on the server end and I can see the packets pushed out; however the video does not play in any player.  If I run wireshark on the receiving machine I can see the rtp packets arriving; however the video player (ffplay, vlc, or quicktime) just sits as though it were waiting for data.  No players give an error, they just go into what appears to be a ready state.  Any thoughts on what is causing this or what I could do to further troubleshoot?
