HI,

How do I specify the "sout-all" parameter using the VLM?
I want ALL the elementary streams from a file, not just the first ( as the default.. ).

Regards,

setup <vlmelementname> option sout-all

Thanks!

Is the CERN going to use VLC ? That would be neat

Well, not exactly.. Trying to rig up realtime streaming of DVB from Finland, mostly for entertainment purposes.

In the side I'm doing a feasibility study of several Grid technologies for this purpose, but they don't seem to be that suitable for _realtime_ streaming, at least yet..

Why would anyone want to use grid computing to do live streaming ? isn't one server enough ?

First question:
That's what I'm trying to find out
Grid computing ain't just about computational power anyway.. Storage, Virtual Organizations, watermarking, encryption etc. They all fit under the vague term called Grid..

Second question:
In the scenario with around ten DVB channels, that you want to stream realtime to another country/continent as efficiently as possible, the answer is definitely no. Encoding MPEG2 to MPEG4 takes quite a lot of power..

At the moment I would say that using a cluster you could roughly encode two channels per computer in the cluster, using reasonably ok computers. After all you cannot run the servers on 100%, as the bitrate is fluctuating quite a lot..

And in the case of sparse bandwidth, encoding into h264 would be interesting. But encoding quality DVB, and in a couple years HDTV, becomes practically impossible using clusters. Especially doing that realtime

seems intersting (although i don't really get the difference between what you call grid computing having 2 videos transcoded per computer and just having 2 videos transcoded per computer without calling it grid)

btw, let us know when you manage to do software HDTV (or normal TV) h264 encoding

Well, in the case you would like to call the system a Grid, you would practically just have one virtual computer. You wouldn't care ( or perhaps even know ) which computers do the calculations. Same think about their location, ownership and number.. It could be a few ancient 486's or a Cray doing your h264 encoding.
When I mentioned two DVB streams per computer, I just refered to the real-life situation..

Realtime? Sure, is should get it running soon on my laptop..

Hi Friends,
I am trying to stream MPEG-4 ES data over the network.I tried with mostly all types of video streaming players ,includeing VLC,unrealstreaming player etc.But not able stream that data.Some players gave error message as unknown data format.Can please suggest any ideas to stream MPEG-4 ES data over the LAN.
