I have also had success without ffserver; however, if I connect directly to the nginx server I would not be using multicast (if I am understanding correctly). The nginx-rtmp module does suggest that it can be used to multicast though I always assumed that was via a setup like the one I described, how were you able to multicast just with nginx?

For testing, I will work on creating the original stream with ffmpeg to see if that effects my final results. If that works I'll see about searching for a different UI.

[FFmpeg-user] OBS multicast
Hello all, My goal is to create a live stream using OBS and play it on many in-house machines using multicast. Right now my attempt looks like: [OBS] -> [nginx w/ rtmp module] -> [ffserver/ffmedia with rtp] -> [any client; I've tried vlc, quicktime, ffplay] I keep running into issues and I haven't had much luck troubleshooting them, so I am curious if anyone has accomplished something similar and could share their setup. Is this a good approach, or should I look in a different direction? Thanks, Eric ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
[FFmpeg-user] RTP Multicast doesn't play
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? ffserver.conf HTTPPort 8090 RTSPPort 554 HTTPBindAddress 0.0.0.0 MaxHTTPConnections 1000 MaxClients 200 CustomLog - File /tmp/1.ffm FileMaxSize 5M Launch /usr/bin/ffmpeg -i "rtmp://172.16.10.86/pos/test" -flags:a +global_header -pixel_format yuv420p -acodec libfdk_aac -vcodec libx264 -s 640x368 Format rtp MulticastAddress 224.1.1.17 MulticastPort 5000 MulticastTTL 63 NoLoop VideoCodec libx264 VideoSize 640x388 AVOptionAudio flags +global_header AudioCodec libfdk_aac Feed 1.ffm Format status ACL allow localhost Thanks, Eric ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
[FFmpeg-user] FFM moving time segment
Hello, I am trying to send an rtp multicast of a stream with the configuration below. It works; however, when the max file size is reached (or the disk fills up if that parameter is excluded from ffmpeg) the program ends. The desired behavior would be to just keep a small section of the stream as per the docs the ffm file can "store a moving time segment of an infinite movie or a whole movie." The current behavior confuses me as clients are able to play the sdp file and receive the content from the beginning which seems inconsistent with multicast. How do I make ffmpeg create an FFM with a moving time segment of an infinite movie?
