Hello All

Id like to know if VLC can multicast a stream to WMP clients ?

I want the video to be synchronised on the differents WMP.

Tries differents things, udp, http+asf... with no success

Thanx

PS: i guess udp multicast is better because i plan to have WiFi clients

It is my understanding that multicast does not play well with WiFi. Google that, I've never tried.

mms: or mmsh: might be the key, although WMP doesn't support it anymore, so version dependant (maybe)

.ja.

check that, I did have multicast streaming across a consumer switch. Both the Wireless and Home plug adapters were hosed, even though the connected machines had nothing to do with the streaming.

Stopped the stream , and the MAC browser on the wireless came back to life.

Things that make you go HUH.

Although this doesn't help the WMP thingie;

thanks to remi @ http://www.remlab.net/:

17 June 2008 - DCCP is so convenient

This only works on Linux:

% LOCAL_IP=192.2.0.1
% vlc music/*.mp* --loop --sout \
"#gather:rtp{proto=dccp,dst=$LOCAL_IP,mux=ts,sap,name=\"DCCP channel\"}"
% vlc -S sap


Nice replacement for multicast, especially on a wireless LAN.

And for the WMP thingie, the audio part:

File: Track.wav

Streaming:

Outputs select HTTP: for access, local machine (server) IP address to listen on port 8080 for request.

Profile, Encapsulation 'ASF' for mux
Profile, Audio Codec 'WAV' 128kb/s 2 channels

HTTP of course, will not have synchronized playback.

Ctrl-U at WMP enter URL HTTP://{Ip.address.as.above}:8080

that should do it.

VLC Multicast 224.0.0.1:7777 works just fine with WIFI, i used to use it all the time to muticast MPeg2 DVDs over the LAN through my old and slow 22Mbit/s (MAX bitrate,more like 15Mbit)11g kit (3COM) and VLC/MPC/MP9 with the right codecs/splitters decoding it (ffmpeg is fine)on the PC playback devices etc.

it might be that some 11g routers dont pass on the multicast packets due to some oddball firmware setting, so you might need to search on yours....but it does work fine for many people.... and switchs should'nt care as they dont process any packets, just passes on whatever comes along.

There is alot about this I don't know - But I believe that a managed switching hub won't pass the broadcast to ports that have not subscribed to the multicast group (IGMP), as long as you use the right network number - 224.n.n.n may get passed to all anyway.

And it wasn't the multicast I was having trouble with on the wireless, it was the normal HTTP traffic that was bogged down. That could well be a configuration problem with the Wireless APs, I don't know, I didn't explore that.
