Hi
i have a steam URL http://xxxxx in MPEGTS in and i would like output flow with udp multicast output
How may i do ?

You need to add MPEGTS Out, set some application/stream name and select source from MPEGTS In, then On UDP streaming settings specify destination IP/Port and in Source application/stream set name you have set in MpegTS out.
Please read these articles for MpegTs and UDP setup:

Hi Denis,
Thanks for your reply
I have done and I have on my pc video on udp://@239.0.3.1:1234 but there is a new problem
There is many freezz image because with udp flow in the statistic of the video on VLC , the bitrate video incoming is variable and there many videos lost frames

Is there a solution to solve he issue?
Is there RTP multicast proocol on nimble?
Regards Lorenzo

Nimble send UDP stream with same rate as data comes in, I suppose your source MpegTS stream also has bitrate fluctuations. Unfortunately, there are no options to normalize bitrate, I could only recommend to translate stream by ffmpeg with -re parameter.
Sorry, RTP is not supported.

Hi Denis,
but when I am connected on the MPEGTS out flow , I have no issue
How may i test with translate stream by ffmpeg?
regards

Hi Denis,
i have lauch this
ffmpeg -re -stream_loop -1 -i http:/xxxxxxxx -c copy -f mpegts rtmp://192.168.1.96:1935/nimble_live/test

On the nimble serve its ready but no bandwith anf after few minutes

Try to remove "-stream_loop -1" parameter - it needed when you want to send some file repeatedly, it will not work for input live streams.

Hi Denis,
thanks for your help.
1/ Ok i may test... this but i think -f mpegts with rtmp , you think it s possible?
2/ If i use
ffmpeg -re -i http:/xxxxxxxx -c copy -f mpegts udp://239.0.0.1:1234

I see normally i may put this source in MPEG-TS UDP setting ,
- in the line -f mpeg-ts udp.... May i specify a multicast adress ( or the nimble server or loopback because , i may read with VLC Locally but on other PC on the LAN i see the packet with wireshark but i cannot read Video

On th enimble server in MPEG-TS i have put 239.0.0.1 1234 but it not see the flow
