Dreambox Enigma - streamts configuration?

[Unknown user #1]

Calling Dreambox Linux (Enigma) gurus!

I need to write a script for streamts, which should do the following:

1. Listen to range of ports (say, 10000-10100)
2. Map lookup table in accordance with port requested
3. Issue streamts command according to lookup table.

In short, if request came in form of:
h**p://192.1.1.1:10000

that means user want to stream channel BBC 1 and issue then issue command in such format:
streamts 192.1.1.2 10000 <VID> <AID>

where:
192.1.1.1 is IP address of Dreambox
192.1.1.2 is IP address of stream recipient
VID is BBC 1 Video ID
AID is BBC 1 Audio ID

Similar for other channels, so for BBC 2 it should be
streamts 192.1.1.2 10001 <VID> <AID>
and
h**p://192.1.1.1 10001

This way, it should also switch channel according to port number (hence lookup table).

Any ideas on how to do this? Do you know some Dreambox Linux forum where I can get help with it?

Hi T'Rookie, I am not quite sure what you are trying to do here. The Dreambox can only receive/pass on one channel at a time and that can be done by by means of VLC/Dreamview or similar. Are the requests being sent from local lan connected pcs or via internet connections?

I know about 1 channel limitation This is not the issue.

The problem is that I want to stream video from Dreambox/TM9100 to my UPnP AV player (DLINK DSM-320RD).

To do so, I installed Twonkyvision for DM7020 and forced it to accept VLC stream. Unfortunately, Twonky only understands VLC links in following format:
h**p://<IP>:<PORT>

whether Dreambox is outputting video via following command:

h**p://<IP>:31339/0,<VID>,<AID>

ATM I have to run VLC on my PC, which is just redirecting video from Dreambox to er... Dreambox (Twonkyvision on Dreambox, to be precise). Then my UPNP player picks it up.

But the whole process is awkward and I am trying to simplify it.

BTW, Dreambox video on UPnP player looks great

Don't really do Linux scripts, but of course it is possible to do what you want, assuming you can:

Use the standard hooks to initiate the background task, either on demand or at startup

Write the code to listen to the requests coming in and capture both the port number requested and the requestor's IP address, assuming that this isn't passed as a parameter.

Manually store the static lookup data in some kind of datastore - what about an .xml file? This would obviously have to be indexed by port number and contain all the PID data for each channel.

Write the code to build and execute the streamts command using the requestor's IP and tabled PID data

Put something in place to kill the task when it's done and cleanup

Can't help any more than that, as I don't really write complex scripts, and I sure don't know much about .ts streaming more than the basic VLC parameterised jobbie.

Thanks for reply.

It looks like it should be possible to change /etc/services to include table of ports and streamts entries. Then to change inetd.conf to include actual commands to call the streamts with VID/AID parameters.

If this article is right, it should be pretty easy task to do Of course, reality might have nothing to do with the article, but I'll give it a try.

Dammit! The file system is read-only and I forgot about it!


Looks like the only way forward is to obtain source code and recompile the whole image...

[BGonaSTICK]

The rights to the file system can be set as you wish, and the script doesn't have to be compiled? :?

The system is sitting in flash and I can't chmod it
It looks like I would have to prepare my own image, which is quite a task for me.

Ok, I know you posted a long time ago but I have half solved it so I thought I'd post. My scripting is not good so anyone should be able to improve onthis but it works for me.

First off you need a script.

stream.sh

#!/bin/sh
# Make web interface change to the correct channel (junks outputs and errors) n.b. Change path to correct one.
wget -q http://localhost/cgi-bin/zapTo?path=...1:c00000:0:0:0: > /dev/null 2>&1
sleep 2
#starts streamts passinng in Program Stream switch, reads (stdin) from file
/usr/sbin/streamts -ps < pids.txt
exit 0

N.B. This script needs a lot more work , like checking if streamts is already initated and killing it first, but it'll get you going..

-------------
Next you need the pids.txt, took me a while to figure out as it must have the following format. The 2 pids I have set up are in the first line 0xa5,0x65..

GET /0xa5,0x65 HTTP/1.1
Host: 192.168.2.101:31320
User-Agent: VLC media player - version 0.8.6b Janus - (c) 1996-2007 the VideoLAN team
Range: bytes=0-
Icy-MetaData: 1
Connection: Close

Then you need to add a line like this to the inetd.conf

313320 stream tcp nowait /etc/stream.sh

Then: killall inetd
Then: inetd

Finally the dreambox need to have localhost specified as a trusted source, you can do this though the web interface..oh and of course chmod the script to 755.

Now just open VLC and http: Dreambox:31320

Works well on my DM500+ running Gemini 4.4
