View Full Version : Live Streaming with VLC

06-19-2008, 11:27 AM
I work for a rural telephone company that has recently started an IPTV service.
We deliver IPTV to the home using standard DSL lines to a set top box at the customer premis.
We have just built a new studio centered around a VT5. We are mostly doing live to tape and post production work. I was experimenting with live stream to the web and that all works fine except that I can't use that stream on our multicast network. I did some experiments with VLC and I can stream video files and even DVD from our VT5 PC to a set top box using VLC on our multicast network. When i try to stream from the toaster card itself all i get on the set top box is audio with no video. I'm not sure if i need a plugin for VLC to properly read the toaster stream or what.
If i can get this function to work we will be able to provide true live broadcasting over our IPTV network. This is a feature that will be very popular with the other telcos that are doing the same thing we are.

I am aware that i could plug a hardware encoder to the main out of the SX-84 but i don't want to spend another $20k for an encoder if a simple software program will work.

So Newtek, any ideas from those cool hi-tech brains?
I submitted a ticket to tech support on this but I figured the forum might be able to help as well.

We have the same problem with VLC and VT cards.

It is strange, as VLC 'reads' most installed devices and directx capable drivers.

As a someone who streams h.264 video for broadcast I would recomend that you invest in a PC with a capture card (we use a cheap $500 Dell with a osprey 240 $300/ capture card) running VLC

the total solution is a bit more expensive than a dedicated encoder box (but an adtecinc h.264 encoder is only $3000) I would not run a VT machine direct to air, the risk of a crash is just to great.

How do the set top boxes cope when a multicast stream is just terminated mid event? Does the middleware cope or do the boxes crash - generating consumer support calls etc?
