How to Use Vlc as a Broadcast Server in Linux

[miyop]

I have TBS6981 DVB-S/S2 card and two computers connected to the same network. One works with linux using only command line. The other is win7. Now;

1. I will get dvb-s signal with vlc player (in linux machine)
2. Transcode -maybe it is not necessray- it into a stream. (in linux machine)
3. Send this stream to the other computer(win7) and play it again in vlc player.

Meanly I will use linux machine as a server and win7 will be a client. I would be very appreciated if anyone could help.

probably best to use an app designed for that, dvbstream or mumudvb Im told work well.

Hi miyop.

If you are using a desktop enviroment in linux, you can start VLC and use "Emit" option on "Media" menu. There select "Capture Device" and "DVB-S or "DVB-S2".
Complete Frequency and Symbol Rate.
Click on "Emit"

In "Emit" dialog click on Next, in Destinations select HTTP (for example) and click on Add. There, deactivate (if you want or delect opitons) "Active transconding". Click on Next and to finish, click on "Emit"

Go to w7 machine, open VLC and open the stream, for example http://192.168.1.1:8080/ (being 192.168.1.1 the ip of linux machine)

If it util for you, in my blog you can find an Step by Step tutorial to do this with pictures, but only in spanish.

Best regards.

It is necessary for me to do it on vlc.
And I have no user interface. I have to work on command line.

Hi miyop.
From command line use cvlc, and some like this.

Code: Select All Code

cvlc -vvv --color --ttl 12  --ts-es-id-pid --programs=161 dvb:///dev/dvb/adapter0 \
    --dvb-adapter=0 --dvb-frequency=11603000 --dvb-srate=8500000 --dvb-voltage=13 \
    --sout-standard-access=udp --sout-standard-mux=ts --sout \    '#duplicate{dst=rtp{dst=address1,mux=ts},select="program=161",dst=rtp{dst=10.0.0.2,port=5004,mux=ts},select="program=161"}'


Additionally, you can find more details about vlc stream in http://www.videolan.org/doc/streaming-h ... /ch09.html
Best regards.

dvbstream or mumudvb are both command line applications

If it won't confuse you, I'm going to give another input example:

vlc -vvv dvb:// :dvb-adapter=1 : dvb-polarization=H : dvb-srate=2800000 :dvb-fec=3/4 :dvb-frequency=12569000000 --sout '#standard{access=http,mux=ts,dst=server_ip:server_port}'

which gives in return:

For an input like below I get a different error:

Could you understand what the problem is? I think sending the stream is ok. Because when I send a video found on my home directory over the network I can take it from another computer. So I think that the problem is to open the dvb-s signals with vlc.
