VOD Howto

[bodrick]

I'm currently working on a VOD howto that will cover some of the more interesting things out there, if there is any interest in such a thing let me know, if I get enough interest I'll put it on the Wiki too.

Hi ...boddrivk Great idea.........

Well I'm very interested about VOD; I'm analyzing the flow work since the VLC (Client) solicits to sever (VLC-VOD) some video; Well I know the the client uses the Live.com libraries(RTSP-Client) to communicate to sever and decide the port number in which the client listen to incoming streaming from the server(RTP over UDP) the last one using the SDP protocol.....Can you tell me if you know:
- who decide the port numbers(client or server)??
- where are this source code(in the VLC or any other library)??
Thanks in advance......

In regards to what port the communication happens on, when setting up VLC on the server side, you pass in the port that the servers listen on for RTSP requests. The switch --rtsp-host.

Code: Select all

vlc --rtsp-host 0.0.0.0:5554

This will set the VLC server to listen for RTSP requests on port 5554.
In communicating back and forwards, I'm making the assumption that a random port is negotiated for the acutally streaming. Someone else can correct me if I'm wrong on this.

In regards to where in the source code, I honestly don't know, I've not really run over the source with a fine comb, mostly I've played around with making updated ebuilds for Gentoo and some of the external libraries like Gpac, and x264.

I've been really busy with a few projects for work and not had a chance to sit down and write anything, however the one major project I'm working on is coming to a close in the next week so hopefully I can start working on the guide then.

Really interested by an how-to when you can....I try to make a vod server for testing, but I don't find documentation which help me and i have difficulties

[kingbell]

It is a good work.
Thanks

To Quote:

Video On Demand
Basic example

First launch the vlc

% vlc --ttl 12 -vvv --color -I telnet --telnet-password videolan --rtsp-host 0.0.0.0:5554

where:
12 is the value of the TTL (Time To Live) of your IP packets (which means that the stream will be able to cross 11 routers).
telnet launches the telnet interface of the vlc.
videolan is the password to connect to the telnet interface.
0.0.0.0 is the host address.
5554 is the port on which you stream.

Then you connect to the vlc telnet interface and create the vod object

new Test vod enabled
setup Test input my_video.mpg

You can access to the stream with:

% vlc rtsp://server:5554/Test
where:
server is the address of the streaming server (IP or DNS)
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=
OR YOU CAN fire up vlc's gui and select File-Open Network Stream- and select rtsp and rtsp://server:5554/Test

AND THEN What Really works for me (to quote again, from up the page)

Configuration Files
A VLM configuration file is a list of command lines : one line corresponds to one command line.

To create a configuration file, just edit a text file and type a list of VLM commands. Beware of recursive calls: you an put a load (file) in a configuration file which can lead to recursive inclusion of the same file and result in VLC's crash.

As of versions > 0.8.1, any line where the first non white space character is a # is considered as a comment.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
So anyways, your configuration file look like this:

new test vod enabled
setup test input test.mpg

new test2 vod enabled
setup test input test2.mpg

save it with your videos with a .vlm extension

and then, cd into the directory where you have your videos,
and fire up vlc by typing

vlc --vlm-conf nameofconfigfile.vlm --ttl 12 -vvv --color -I telnet --telnet-password videolan --rtsp-host 0.0.0.0:5554


you know, I guess we could leave out the telnet and telnet-password flags, now that we are feeding it via a vlm-conf





The quotes are quoted from:

yes please.
For me is not clear how to stream DVD on demand.
I work for a school district and we have a juke box of DVD and i'd like to stream the DVD on demand (in some case also multicast)

Hi bodrick,

Thanks for putting up the VOD howto for VLM! It would be a great help.

It may be naive of me to make following statement, but I am wondering if it is reasonabe to consider a feature (or if it already exists, please kindly point out where/how to get it).

Currently in VLM, before I can request a media via VOD, I need to setup the media and its properties ahead up time using:

Code: Select all

new testObject vod enabled setup testObject input test.mpg ..

Subsequently, this test vod media object can be requested via

Code: Select all

vlc rtsp://server:5554/testObject

While it is trivial to setup one VOD media, it would be tedious if the VOD media count goes up. In contrast, the Web Server (e.g., apache) world seems simpler. For instance, you simply drop your files (resources) in a given directory under the Web Server Document Root, and it becomes accessible via a URL (describing the directory structure).

For instance, we drop the media file, test.mpg, in testDirectory/testSubdirectory/ (relative to the Web Server's document root directory). Without any more setup, this file is accessible via

http://webserver:port/testDirectory/testSubdirectory/test.mpg

Can this be done currently in VLM/VOD? If not, would it possible to implement this new features?

[michiel]

i don't want to use telnet, so please don't forget the http-method

[MrExNice1979]

just do it man

[bodrick]

Sorry for not getting it up just yet, I've been really busy with my professional life, I've had so many projects come down the pipe etc, and its been a while since i played with VLC on my linux box, I'll keep you posted on when and where.
Thanks for the support though

Hi everybody,

I'm trying to do some VOD with vlc, but:
- if I use rtsp protocol, I can use only vlc as client
- if I use http, nothing works

Does anyone got a solution for VOD, with a different client than vlc?

thanx

[marcuschan]

any news in year 2007?

[marioja]

I have tried all tricks in the book and I cannot get VOD to work using HTTP. Can anyone give a simple working example? Thanks.

[dineshatit]

please help me to solve the problem ..

Hello,

Can anyone let me know, What is the maximum instances of a concurrent streams does a VOD support ??

with regards,
Rag

[dionoea]

There's no fixed limit. It depends on what your streaming, what hardware you have, what OS you run and how much bandwidth you have.
