DVB-S Streaming with VLC

[causality]

Hi,
I am using Slackware 11 on kernel 2.6.21.5.
I have got SkyStar II DVB-S Card.

I want to stream a channell to our network.

My VLC version is
VLC version 0.8.6c Janus

I want to watch a channel, it's named ZTV. ( Frequency = 11852, SRate = 4444, TStreamID =86 )

I readed "VideoLan Streamin Howto" and also I readed Chapter 9 (Stream a DVB Channell).
But I didn't do it.

I tried this command

Code: Select all

vlc -vvv --color -ts-es-id-pid programs=86 dvb: --dvb-frequency=11852000 --dvb-srate=4444000 --sout-standard-access=udp --sout-standard-mux=ts

Output is only that

Code: Select all

VLC media player 0.8.6c Janus starting VLC root wrapper... using UID 0 (root) *************************************** * Running VLC as root is discouraged. * *************************************** It is potentially dangerous, and might not even work properly

I think the very first thing you should do is to follow the advice of the vlc message:
Do not run vlc as root!!

VLC and access to dvb hardware works very well for a normal enduser (provided the dev-files have the proper permissions but in a well installed recent Linux system this is normally not a problem).


For your streaming you need also a add an option of the IP-address and udp-port where you want to stream, i.e. you should add the following option:

Code: Select all

--sout-standard-dst=127.0.0.1:2345

Here I have put as example the localhost address and 2345 as some arbitrary udp-port. I think in doing so can start a second vlc on the same PC which should be able to read the stream with a command such as:

Code: Select all

vlc udp:127.0.0.1:2345

(also localhost since you do not leave the PC). Of course if you test between two different PCs you use in the streaming-vlc the IP-address of the client and in the client vlc on the other PC the IP-address of the streaming server. Be also careful to correctly open or configure your firewall on the serveur and client.

Thank you,
I tried this command now,

Code: Select all

vlc -vvv --color -ts-es-id-pid programs=86 dvb: --dvb-frequency=11852000 --dvb-srate=4444000 --sout-standard-access=udp --sout-standard-mux=ts --sout-standart-dst=127.0.0.1:3456

But everything is same. VLC has given that output, and than close without any information or error.

Did you try to start VLC as a simple user and not as root ?

[causality]

I created a user that named vlcuser. Than I tried same command again and i didn't see anything again.

I saw only these :

Code: Select all

vlcuser@KREATV01:~$ vlc --vvv --color -ts-es-id-pid programs=86 dvb: --dvb-frequency=11852000 --dvb-srate=4444000 --sout-standard-access=udp --sout-standard-mux=ts --sout-standart-dst=127.0.0.1:3456 VLC media player 0.8.6c Janus vlcuser@KREATV01:~$ |

But I am sure about drivers,etc... because i can watch this channel via Kaffeine.

[kmf31]

Before you test the streaming you need to verify if the simple watching with vlc works. Try your command line but without the tree options "--sout-standard-<blabla>". This should give in theory the dvb-s image with vlc.
This allows to verify if you have a generic problem to make vlc work with your dvb-s card (unlikely if Kaffeine works and provided that you are not wrong with some dvb-options) or if your streaming options are not correct with some syntax error.

[causality]

I tried this command now

Code: Select all

vlc -vvv dvb: --dvb-frequency=11852000 --dvb-srate=4444000 --program=86

Output is this

Code: Select all

vlc: unknown option or missing mandatory argument `--dvb-frequency=11852000' Try `vlc --help' for more information.

[causality]

I am sorry, i didn't find any help document.
I wrote vlc --help | grep dvb
I searched in google, too

I want to use VLC.
But I couldn't write a command for watching a dvb-s channell.
Maybe i am asking so easy questions about this subject but i am trying to play

[kmf31]

Did you compile vlc yourself ?

If yes you must be careful to activate dvb-support with:

./configure --enable-dvb ....

(with "...." for your other ./configure options). Without "--enable-dvb" the dvb-support is not included in vlc.

Have also a look here:
viewtopic.php?f=13&t=38890

[causality]

Yes,
I compiled VLC myself.
I used these options.

Code: Select all

./configure --enable-v4l --enable-dvb --disable-skins2 --enable-pp --enable-gpl

than i uninstalled everything and i tried these

Code: Select all

./configure --enable-v4l --enable-dvb --disable-skins2 --enable-pp --enable-gpl --with-dvb --with-v4l

than make
than make install
than I tried this command

Code: Select all

vlc dvb-s://:freq=11852000:pol=V:srate=4444

now vlc opened but it gived this error to me : Unable to open 'dvb-s://:freq=11852000:pol=V:srate=4444'

[kmf31]

Is everything okay with the linux driver of your card ? In particular does your card work with other software such as xine, mplayer, ... ?

Do you have a channels.conf file which is typically used for mplayer or xine and obtained by the scan-utility ?

If yes try simply: "vlc channels.conf" and if it works you save a playlist and this playlist will contain the exact options you need (see the link I gave in the last post).

Try also to make hyphens around the options with strange characters (such as "#" etc.). Sometimes this is the only problem.

[causality]

I tried newly setup.
I checkout vlc trunk version from vlc svn site.
than I compiled again with these options.

Code: Select all

./configure --enable-v4l --enable-dvb make

I tried this command

Code: Select all

vlc --advanced -p v4l

Everything is Ok. But when I try this command

Code: Select all

vlc --advanced -p dvb

I saw only this

It is possible that the dvd-support did not compile because of the missing dvb header-files. I have already explained this in detail in the other topic of which I gave you the link above. Verify and install the dvb-header files and recompile with ./configure etc. This should also work with 0.8.6c (the trunk is still quite unstable).

Verify also the ./configure messages if he accepts the dvb-support (you may redirect the ./configure output in a file using nohup or direct file redirection ... 1> ... or ... 2> ... and then verify in the messages in the file if there are some lines about dvb and if he found the header files).

[causality]

You right.
That is ouput :

Code: Select all

configure: WARNING: cannot find libdvbpsi headers checking for dvbpsi_GenSDTSections in -ldvbpsi... no checking linux/dvb/version.h usability... no checking linux/dvb/version.h presence... no checking for linux/dvb/version.h... no configure: WARNING: linux-dvb headers not found checking linux/dvb/frontend.h usability... no checking linux/dvb/frontend.h presence... no checking for linux/dvb/frontend.h... no configure: WARNING: linux-dvb headers not found

What can I do now ?
Because I have got these file already.

Code: Select all

root@KREATV01:/usr/src/linux/include/linux/dvb# ls Kbuild audio.h ca.h dmx.h frontend.h net.h osd.h version.h video.h

[kmf31]

You must copy them to /usr/include by:

cp -r /usr/src/linux/include/linux/dvb /usr/include/linux/

provided that "/usr/include/linux/dvb" does not yet exist !

There are people claiming to replace /usr/include/linux by a symbolic link to /usr/src/linux/include/linux but this is normally WRONG! In /usr/include/linux there are special and patched linux-header files provided by your distribution and the other folder /usr/src/linux/include/linux contains unpatched headers of clean kernel-source-tree. There are good reasons that these are separate!

However for the subfolder for dvb support you may simply copy from one to the other place and the dvb-header files behave nicely in the sens that the exact version of these files is not really a problem, i.e. you copy now and it will still work in a year (to compile vlc) even if you change the kernel in the meantime.

Thank you so much.
I copied include files, and i installed libdvbpsi.
Now, Dvb options are available.

I will try streaming, after lunch. I will eat my food so happy and quickly.

This is the szap tool's output.

Create the file "channels.conf" (using the scan-utility) and then try simply "vlc channels.conf" and save a playlist as I have already mentioned above and described in the other topic.

It is possible that you missed some necessary options in the command line and which you might find in the playlist.

Owww

Everything OK ,now.
I have got a diseq system. I learnd I must give an option "dvb-satno=1".

Code: Select all

vlc dvb:// :dvb-adapter=0 :dvb-frequency=12507000 :dvb-srate=3900000 :dvb-device=0 :dvb-inversion=2 :dvb-satn o=1 :dvb-voltage=18 :no-dvb-high-voltage :dvb-fec=9
