passing DVB-S2X parameters in a M3U playlist

Post by fergycool »

So I'm trying to get the Fransat channels on Eutelsat 5W tuned using Satip-axe running on a Telestar Digibit R1.

From a few notes in the Github repository Multistream/DVB-S2X is supported on this hardware and the later builds of satip-axe support it.

Except I have no idea how to specify these in the RTSP URL of the M2U playlist file

For example I'm looking at France 2 HD. According to Kingofsat this is on a stream with three other channels.

These four channels are on a single multistream using DVB-S2 PLS:Gold+50416 - 8PSK Stream1.

How on earth do I pass this information in that URL.

Code: Select all

#EXTINF:0,France 2
rtsp://@192.168.1.22/?src=1&freq=11509&pol=H&msys=DVBS2&mtype=8PSK&sr=29500&pids=0,120,130,110,120,
Any pointers would be gratefully received!

Thank you!
Cheers

I'm not exactly an expert on this, but as far as I understand, different 'channels' within the same broadcast 'stream' (i.e. freq etc.) are distinguished by the PIDs. King of Sat shows the relevant PIDs for each channel so you should be able to set those appropriately in the m3u URLs.

As a minimum you need 0 and the PMT (usually 3 digits) and then the VideoPID and whatever AudioPIDs you want. As I said, King of Sat lists these.

Hope this is of some use.

Based on the axe code: there are few arguments that needs to be specified: plp and plsc

Here is the reference Pr: https://github.com/catalinii/minisatip/ ... 34f66de2e3

I'm really sorry. But I completely missed your kind replies to my post!
So taking France 2 as an example.
I've got this as the full stream ID

Code: Select all

<transponder frequency="11509000" symbol_rate="29500000" polarization="0" fec_inner="6" system="1" modulation="2" is_id="1" pls_mode="1" pls_code="50416" /]
Then Kingof sat shows me that the VPID is 120, with the audio ones being 130,131 and 132.

So I've tried to use something like this:

Code: Select all

#EXTINF:0,France 2-PLS
rtsp://@192.168.1.22/?src=1&freq=11509&pol=H&plp=1&plsc=50416&msys=DVBS2&pids=120,130,131,132
Except VLC just gives an error:

Code: Select all

Created new TCP socket 38 for connection
[00007ff3b8c04e30] live555 demux error: RTSP PLAY failed 404 Not Found
[00007ff3b8c10990] satip stream error: Failed to play RTSP session
What am I doing wrong here? Thanks!

I think I'm getting more information on this. I tried installing TVheadend as it appears to automatically adds Multistream muxes. Except every Multistream mux on 5W fails to scan.

I'm using a Telestar Digibut R1 running the SATIP-AXE custom firmware.Apparently the hardware and later builds all support Multistream.

I wonder if I'm missing some config options that are needed to enable that!

So stuck now! Gave up on TVheadend. Went back to VLC+M3u files but no luck! I know this must work. but for the life of me cannot fathom out how!

I will tey to get the new minisatip with some debug information if the dvb-s2 parameters are used.

Hi. Thanks.

Yes I'm using the minisatip in satip-axe:

Code: Select all

80015361.minisatip version 1.0.4-191fe62, compiled in Jan 31 2021 14:50:11, with s2api version: 0501

Code: Select all

Welcome to SATIP-AXE server 202101311452-17

Code: Select all

MINISATIP_OPTS="-p http://192.168.1.22:8080/all.m3u  --diseqc-multi *:2 --diseqc-timing 1:155-54-15-15-15-0  -A 0:0:1,1:1:0,2:1:1,3:2:1,3:3:1"
The M3U file contains this line:

Code: Select all

rtsp://@192.168.1.22/?src=1&freq=11509&pol=H&msys=DVBS2&sr=29500&mtype=8PSK&plp=1&stream_id=1&pls_code=50416&pls_mode=gold&pids=120,130,131,132
I am not really sure I have it correct. I have tried many different values and variations of the parameters. A definitive list if what the multistream parameters are would be helpful!

I've been going crazy trying to get this working. :-) I'#ve seen so many posts saying it should work. I even spent an hour on the roof yesterday with a meter trying to check that I'm getting the right satellite! Obviously I must be as I can get all the unencrypted non-multistream channels on 5W. It's just the Multistream ones I'm failing to get.

Many thanks!
Cheers
