Introduction

On this section you will be guided through a series of steps to finish the setup of your Galicaster Mobile unit. Please, read this documentation carefully and follow its instructions. In case of doubts please take advantage of the Galicaster Community list to make any question or suggestion.

In the following sections you will receive instructions on how to connect and configure you Galicaster unit.

A. Cards and connectors


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.

B. Network Configuration


To change your IP settings, pleas read this official Ubuntu guideline.

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


C. Capture Devices configuration


Galicaster configuration is specified in two files conf-dist.ini and conf.ini. You can download two different models of conf.ini depending on the cards you are using:

Now, it's time to configure the card you've selected. More information about this matter is available here.

C.1 Blackmagic configuration

To list the input standars and formats supported by Blackmagic cards run the following line in a shell:

gst-inspect-0.10 decklinksrc | grep Enum -A 20

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

C.2 Hauppauge configuration

Before running Galicaster you may have to configure your Hauppauge card. Connect your camera and do the following:

Standard selection
You have to choose between a list of standards. To list and select the standard, run in a shell:

v4l2-ctl -d /dev/haucamera --list-standards | grep Index -A 2
v4l2-ctl -d /dev/haucamera -s 0

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:

v4l2-ctl -d /dev/haucamera -n | grep Input -A 1
v4l2-ctl -d /dev/haucamera -i 2

Inputs 1 and 3 are for 4-pin.
Inputs 2, 4 and 5 are for RCA.

C.3 Sound configuration

To have the best audio feedback on your interface you should configure your audio inputs properly.

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.
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.

Galicaster Vumeter
Add this section in the conf.ini file.

[audio]
min = -60
max = 0

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.

  • Press F6 to select the input and F4 to go to the Capture section.
  • You can check the real Gain on Item on the top left corner of the screen.

D. Opencast Matterhorn related configuration

If you have a OC-Matterhorn running you have to ask your Matterhorn system administrator for some information.

First of all, You need the admin host address, including the port. For example:

host = http://fakeadmin.matterhorn.com:80

You also need a digest user - a regular one won't work. There is a default digest account that should be replaced with your own values.

username=  matterhorn_system_account
password= CHANGE_ME

You also need to set up a default workflow and its parameters. Scheduled recordings will have his own workflow and parameters, defined in the scheduling operation, but the recordings started manually won't. The usual parameters you have to set up are captions and trimHold, which default to False. The normal configuration is:

workflow = full
workflow-parameters = trimHold:true

If you set up more than one parameter:

workflow-parameters = trimHold:true;captions=True

Finally, you have to decide if your recordings will be recorded automatically or not. If you want to do so, set default to True. All the configuration together will look like:

[ingest]
active = True
default = False
host = http://fakeadmin.matterhorn.com:80
username = matterhorn_system_account
password = CHANGE_ME
workflow = full
workflow-parameters = trimHold:true

This piece of code must be written on one of the configurations file. Be aware that values in conf.ini will overrule its equivalent in conf-dist.ini.
