VideoLAN and Amino Set-top box

Postby Jinny » 22 Nov 2004 10:41

I read some document from Videolan.org website. It says that VideoLAN can do Video on Demand so I tested VideoLAN (VLC0.8.0) with Amino STB. But, what I can do is only multicast live streaming using rtp protocol (The movie doesn't start at the beginning of the file).

Anyone has any idea how I can set up VLC and Amino STB for video on demand (when open the content, it starts at the beginning of the content). Otherwise, Please suggest me other STBs that can work with videoLAN for video on demand application.

Thank you in advance,
Jinny

I did my master thesis using the Pace DSL 4000 STB setting up a itv platform and basic of a VOD service.
I used video lan for streaming (multicast rtsp address) on the STB and it worked perfectly !

Hi karlito,

How can you setup videoLan for VoD service? Did you select udp/unicast mode? To use "multicast rtsp address", does the STB play the content at the beginning of the file? Please give me some more detail because I have just started with the VLC and I don't have much knowledge about it.

Hi Jiny,

to set up VLAN as VoD service with a STB it is the way I done it:
I used rtsp multicast address on the STB (I did not try unicast, I dont know if it would work). You first "tune" the STB to the mutlicast address (on the PACE DSL 4000 HTML and JavaScript able it is in JavaScript: mediaObject.load("rtsp:///multicast_address").
Then, I used some tricks:
on an HTTP server accessible from the STB you store a script that will start the video ie with the line: vls -vvv -d udp:multicast_address your_file.
then the video should be decoded on the STB.
using a the command : "echo $!" it returns the PID (processus ID), you can stop the server (then the video) when you want.
As I said, it was the basics of a VOD, so you cant pause. go forward ot whatever, it is because VLS is not RTSP commands able and it was not the only focus of my thesis.

Anyway, I hope you ll succeed to do something.

thinking about it, you can enhanced the VoD service using command line on VLS...
using the same principle to start the video, you can create scripts to pause, forward... the video.
