Streaming from console-only server

[letex]

Hello everybody.

I'm trying to stream out with vlc from my ubuntu-server system.

Explanation
My LAN is composed by a Ubuntu-server system for Downloads and Shares over the LAN. I also have an "Imagenio" decoder, that is an decoder of IP-television from my ISP (TV over ADSL). In this environment is possible to block the one single channel on the router and use it IP for streaming video to the decoder.http://www.adslzone.net/postt30870.html

The streaming have to be on MPGA audio and MPEG-2 video format. If I use the windows or linux GUI to do the streaming its works without problem.

I want to use the console-only vlc in my ubuntu-server system. My idea is to write a script for doing over ssh:

Code: Select all

./play.sh /path/to/file

And streaming the video to my Imagenio decoder

Trying to do it I installed on ubuntu-server: vlc, ffmpeg and transcode. The :sout string obtained from the windows GUI is:

Code: Select all

vlc :sout=#transcode{vcodec=mp2v,vb=800,scale=1,acodec=mpga,ab=128,channels=2,samplerate=44100}:udp{mux=ts,dst=239.0.0.92:8208} :no-sout-rtp-sap :no-sout-standard-sap :sout-keep

And the output in console is:

Code: Select all

VLC media player 1.0.6 Goldeneye [0x91c5a78] inhibit interface error: Failed to connect to the D-Bus session daemon: /bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed.

How can I fix the command for being able to streaming from console to my tv via ssh??

thanks in advance!!

You are missing "" around your sout string
And use -Idummy too

Hello

The " " are double or simples??

I was trying to fix the command to can use it. But it still doesn't work.

In my ubuntu server, the ffmpeg packet is not with ENCODER for mpeg2, I had to re-compile it from sources and now it can Encode mpeg2, but there are still errors on the command.

Code: Select all

cvlc File.avi :sout="#transcode{vcodec=mp2v,vb=800,scale=1,acodec=mpga,ab=128,channels=2,samplerate=44100}:udp{mux=ts,dst=239.0.0.92:8208" :no-sout-rtp-sap :no-sout-standard-sap :sout-keep

and the result is:

Code: Select all

VLC media player 1.0.6 Goldeneye [0x866ca78] inhibit interface error: Failed to connect to the D-Bus session daemon: /bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed.

no udp matched?? how can i fix it??

I prove to encode with ffmpeg to mpg file with mpeg2 codec and it works.

thanks in advance

OK, I solved it!!

the problem was that my VLC version in Desktop doesn't match with the server one, then, the output command was not the same. Then, when I configure the output command in desktop, it wasn't run OK in server.

In VLC 1.0.6 goldeneye (server side):

Code: Select all

cvlc /patch/to/File -Idummy :sout="#transcode{vcodec=mp2v,vb=800,scale=1,acodec=mpga,ab=128,channels=2,samplerate=44100}:[b]std{access=udp[/b],mux=ts,dst=239.0.0.92:8208}" :no-sout-rtp-sap :no-sout-standard-sap :sout-keepsud vlc://quit

In VLC 1.1.4 (desktop side):

Code: Select all

cvlc File.avi :sout="#transcode{vcodec=mp2v,vb=800,scale=1,acodec=mpga,ab=128,channels=2,samplerate=44100}:udp{mux=ts,dst=239.0.0.92:8208" :no-sout-rtp-sap :no-sout-standard-sap :sout-keep

The problem is now solved. I did an script using "screen" to leave it running and exit from ssh session

Code: Select all

#!/bin/bash #echo $1 screen -d -m cvlc $1 -Idummy :sout="#transcode{vcodec=mp2v,vb=800,scale=1,acodec=mpga,ab=128,channels=2,samplerate=44100}:std{access=udp,mux=ts,dst=239.0.0.92:8208}" :no-sout-rtp-sap :no-sout-standard-sap :sout-keepsud vlc://quit

Now I'm able to enter by my (Android) phone in server, run the command and view the film from my TV.

thanks for the help!!
