Streaming DV in Real-Time

[lightforce]

I'd like to use VLC at an upcoming convention to stream video and audio of an event in one room to another room in real-time. I plan to use a digital camcorder with a FireWire output (which should give better quality than an analog output), hooked up to a computer running VLC as a server that streams out the DV data over a wired Ethernet network.

Is this feasible? According to the Video Streaming HOWTO, VLC will support it (although I don't want to transcode it like the HOWTO shows). I know that DV has a fairly high bitrate (around 36 megabits/second), so a big concern is bandwidth (especially taking into consideration the bandwidth overhead for the streaming protocol, probably UDP). Has anybody done this before?

If I need to use less bandwidth, are there any suggestions for real-time encoding/transcoding that would give good results?

Thanks!

VLC is a very good software for streaming... I just love it.
But is a general purpose software for playing, transcoding and streaming.

If you only want to stream DV over ethernet, I sugest you to use DVTS instead VLC. DVTS does only, but exactly what you want.

You must expect a stream of 40 Mb/s.

If you want to reduce the bandwidth encoding/transcoding, VLC is your software.

I use DVTS and VLC together. DVTS for stream DV over my LAN, and VLC to transcode the stream outside my own LAN.

VLC (MPEG TS, MP4V or DIV3 2048 kb/s , MP3 192 Kb/s) is a very reasonable quality.

I'm trying to do the same thing with VLC- streaming with my dv-mincam thru firewire.

now I know it works cos I can capture all day in Kino using /dev/dv1394/0

but when I use the VLC GUI it says on the Video4Linux tab /dev/video and I'm stumped!

I've tried command lines like so:
vlc -vvv dv/rawdv:///dev/raw1394 -dv-caching 10000 –sout '#transcode{vcodec=WMV2,vb=512,scale=1,acodec=mp3,ab=192,channels=2}:std{access=mmsh,mux=asfh,url=:8080}' –sout-transcode-fps=25.0

and it gives me a bunch of permission errors on /dev/dv1394 and says nothing to play!

I'm using Ubuntu Linux 7.04
any suggestions?
