The application should start and the first thing you see is something like this :

The application is divided in two parts : the right part is the video window. You should see a blue message saying "Camera Started...ready to Stream".
If you have a red message saying "Error initializing camera...Check your devices", maybe you chose the wrong driver for your camera, try to use the other GStreamer script, respectively Video 4 Linux or Video 4 Linux 2.
The left part is the parameters window, containing various sections : input devices, audio settings, video settings, server configuration and recording option.

2. the next step is to set up your parameters and start streaming

You should fill up the following configuration sections before starting streaming :

Input devices :

In this window, you can configure the audio and video devices to use for streaming :

• video device: in case you have several webcams or capture cards plugged in, they will be numbered video0, video1, video2, ... You should set up the right value for your system.
• audio device: in case you have several soundcards on your system, they will be numbered dsp, dsp1, dsp2, ... You should set up the right value for your system.
• driver type: this is optional, it should be set to "Video 4 Linux" or "Video 4 Linux 2" when you start the script.
  But if you started the wrong script, you can change it here.

Video parameters :

In this window, you can set the video parameters of your stream :

• video size: size of the video ( from 160x128 to 720x576, default 320x440 ).
• framerate: framerate of the video ( from 25 to 5, default 12,5 ).
• encoding quality: quality of the encoding ( from 0 to 63, default 16 ).

Audio parameters :

In this window, you can set the audio parameters of your stream :

• audio quality: encoding quality of your audio ( from -0.1 to 1.0, default 0.2).
• audio channels: stereo mode of your audio ( 1 or 2, default 1 ( mono ) ).
• audio rate: sampling frequency of your audio, default 22050.

Server configuration :

In this window, you _must_ set the server parameters for your connection.
Here this script can connect only to an icecast server and you must provide the following fields in red :

• server: this is the name of the server you will stream to, in our case, we will use giss.tv.
• port: this is the port where you will stream to, in the case of GISS, it should be set at 8000.
• mountpoint: this is the name of your channel, it should be set for example to my_channel.ogg.
  WARNING : it should be an .ogg mountpoint here, all video transmission in made in Ogg/Theora format.
• password: this is the password you received when you opened a channel on giss.tv, it should be composed of 5 characters or numbers.

In this window, you can optionally fill more infornmations on your stream :

• name: this is the name of your stream.
• description: this is the description of your program.
• genre: this is the genre of the contents you broadcast.

Optionally, you can set up a recording file to record your program to :

Once you have set all the parameters for your stream ( the only mandatory part is the server configuration part ), you can start streaming using the connection button :
