Janus play multicast RTP stream ?

[sard...@gmail.com]

Hi,

Could you confirm for me that Janus is the solution for our student project:

The project is to stream a multicast video on a private network. And play this stream in a browser.
We use "VLC player" software to stream a video with RTP and on multicast IP (like rtp://@224.0.0.1:5004). Currently, we play the stream on a browser with plug-in VLC player. (Firefox)
The problem is: we don't like to use additional plugin to play the stream in a browser. (poor user experience)
I've notice, the browsers cannot play RTP multicast stream with HTML5 tag or Flash player (only unicast stream with HTTP)
So, Janus can play our RTP multicast stream in a browser ?

For us, it's important to use multicast stream for bandwidth reason.


Thank you.

Hi Amhoh!

You have your project in a public repository? 

Thanks for share with us :)

I get signal from SDI Decklink and stream multicast using ffmpeg.

I send 1 video and many audio streams.

With Janus stream plugin i join video with every separate audio

(we got many live translation)

[str1]

type = rtp

id = 11

description = rus

audio = yes

video = yes

audioport = 17100

audiomcast = 224.0.0.1

audiopt = 111

audiortpmap = opus/48000/2

videoport = 17010

videomcast = 224.0.0.1

videopt = 100

videortpmap = VP8/90000

[str2]

type = rtp

id = 20

description = heb

audio = yes

video = yes

audioport = 27000

audiomcast = 224.0.0.1

audiopt = 111

audiortpmap = opus/48000/2

videoport = 27010

videomcast = 224.0.0.1

videopt = 100

videortpmap = VP8/90000

You can actually play with streams as you want.

If you need only 1 video and 1 audio it's easier to configure.

Hi,

Just to know if ffmpeg is need to run on the same host where janus server is running in order to get the stream via multicast?

As in the RTP example, you have to run gstreamer locally, where in the multicast example it also involve the gstream? So are they meaning that the gstreamer is the publish point of the mulitcast address? and the example configuration in janus is how to get the stream? 

Thank you
