# FFMPEG command to stream video to a Multicast address

ffmpegvideo streamingvlc-media-player

I need to stream a video to a Multicast address.
I heard using FFMPEG we can stream the content.
I used the following command to stream to the multicast address

ffmpeg.exe -i input -vcodec copy -acodec copy -f mpegts -re "udp://239.101.101.1:1234?ttl=1&pkt_size=1316".


But i am not able to view the video in vlc nor in ffmpeg from another system.
I need to view the contents from another machine.

• the '-re' flag is applied to input not output, your command won't work as you have it listed.

• you have your ttl set to 1, that will stop you at the first router, bump it up and see what happens.

This is the simplest way I know to do it.

    ffmpeg -i Plan_9_from_Outer_Space_1959.mp4 -c copy -f mpegts  'udp://239.0.0.1:1234?ttl=13'


Play with mplayer.

    mplayer udp://239.0.0.1:1234
