The Galicaster Mobile Unit comes equipped with different inputs to fulfill your needs on recording multistream material. Depending on the devices you are about to use you should combine those inputs properly.

There are two main combinations, depending on the type of camera (NTSC or SDI) you use to record the presenter. In both cases you have to use a VGA grabber to record the slides. Those combinations will be explained briefly on the next two sections.

Take a close look to the image to identify the ports of each capture card.
Please, take a closer look to the image to identify the ports of each capture card before connecting anything.

h3. B. Network Configuration
----

To change your IP settings, pleas read this [official Ubuntu guideline|https://help.ubuntu.com/10.04/internet/C/connecting-wired.html].

The Network Manager is on the top right corner, Right-button click on the double arrow icon.

h3. CB. Capture Devices configuration
----

* Hauppauge + Epiphan: [conf.ini | http://webfiler.teltek.es/webfiler/galicaster/configs/hau_mobile/conf.ini]

Now, it's time to configure the card you've selected and audio. More information about this matter is available [here|Galicaster:Cookbook]. [here|1.1 Cookbook].

{anchor:bm}
h4. C.1 Blackmagic configuration
To list the input standars and formats supported by Blackmagic cards run the following line in a shell:

{code:none}
gst-inspect-0.10 decklinksrc | grep Enum -A 20
{code}

Once you identified the format you want to capture, edit the _conf.ini_ file you've just downloaded. Search for the _track_ Blackmagic and change the parameters _input_ and _input_type_ for their right values. Some try-and-error may be neccessary since maybe you can't gather all the information from your video source.
The _p_ in 1080p stands for _progresive_
The _i_ in 1080i stands for _interlaced_

{anchor:hau}
h4. C.2 B.1 Hauppauge configuration
----
Before running Galicaster you may have to configure your Hauppauge card. Connect your camera and do the following:


*Input selection*
Depending on the input you are using you have to choose bettween S-Video (4-pin) and Composite (RCA). To list and select the input, run in shell:

{code:none}
Inputs 2, 4 and 5 are for RCA.

{anchor:bm}
h4. B.2 Blackmagic configuration
----
To list the input standards and formats supported by Blackmagic cards run the following line in a shell:

{code:none}
gst-inspect-0.10 decklinksrc | grep Enum -A 20
{code}

Once you identified the format you want to capture, edit the _conf.ini_ file you've just downloaded. Search for the _track_ Blackmagic and change the parameters _input_ and _input_type_ for their right values. Some try-and-error may be neccessary since maybe you can't gather all the information from your video source.
The _p_ in 1080p stands for _progressive_
The _i_ in 1080i stands for _interlaced_

h4. C.3 Sound configuration
----
To have the best audio feedback on your interface you should configure your audio inputs properly. First of all, go to the Sound Manager (speaker icon on the top right corner of the desktop)

To have the best audio feedback on your interface you should configure your audio inputs properly.
*Headphones output*
Regulate this slide bar to a comfortable sound level.

*Pulse input ( Line in):*
_If you are using the Hauppauge card please skip this section_
First of all, go to the Sound Manager (speaker icon on the top right corner of the desktop), select the input you are using and set the values to 100% volume, no amplification.
Select the input you are using and set the values to 100% volume, no amplification.
Later, if you have distortion on your audio input, edit the conf.ini and set _amplification = 1.0_ in the AudioSource device.

*Headphones output*
Regulate this slide bar to a comfortable sound level.
_Recommendation_
----
On the pulse track of your conf.ini, don't leave the value _location_ as _default. List the inputs and set it. This way you won't need to check it every time you switch on your unit. To do that, run in a shell:

{code:none}
pactl list | grep Source -A 2
{code}

Identify the input you want to use, for example
{code:none}
alsa_input.pci-0000_00_1b.0.analog-stereo
{code}

Use the _name_ as _location_ on the _conf.ini_ pulse track
{code:none}
[track3]
name = AudioSource
device = pulse
flavor = presenter
active = True
*location = alsa_input.pci-0000_00_1b.0.analog-stereo*
file = sound.mp3
amplification = 2.0
vumeter = True
player = True
{code}
----
\\

*Galicaster Vumeter*
Add this section in the _conf.ini_ file.

If the NO SOUND dialog is coming in and out constantly, set a higher value on _min_, for example -40.
\\

* Alsa Advanced configuration *

If you still experience problems after configuring the Sound Manager and your Mixer or Sound input device, you should take a look to ALSA.
Run _alsamixer_ on a shell and ensure that your device is not being amplified.
* You can check the real Gain on _Item_ on the top left corner of the screen.
