A. Cards and connectors

You can use 3 different capture cards to record your multistream material on your Galicaster Mobile unit. Depending on the scheme you are about to use, you have to combine different inputs.

• VGA grabber: Epiphan VGA2USB LR
• SDI capturer: Blackmagic Decklink SDI
• NTSC capturer: Hauppauge PVR-350

Once you have chosen which devices to use, you need to connect your camera to the Blackmagic Card (SDI) or to the Hauppauge card (NTSC / PAL ). Apart from that, remember to connect the monitor to the graphic card output, not to the motherboard.

B.1 Matterhorn configuration

If you have a OC-Matterhorn running you have to ask your Matterhorn system administrator for some information. First of all, you 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 need the admin host address, including the port. For example:

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

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

C. Galicaster 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:

• Blackmagic + Epiphan: conf.ini

• Hauppauge + Epiphan: conf.ini

C.1 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 no amplification, 100% volume.
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 confortable 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. You can check the real Gain on Item on the top left corner of the screen. Press F6 to select the input and F4 to go to the Capture section.

D. Troubleshooting

D.1

D.2 Audio problems

There is several reasons for you not having audio input, the usual ones are:

1. You haven't selected the right input.

Run the following code to identify the available inputs.

pactl list | grep "Source" -A 5

Select the one you need, copy the value of name and use it as the Pulse>location value, instead of default. This will fix the audio input, overwritten the one selected on the Ubuntu Sound Manager.

If the input you want to use is not there, the device is not connected properly or it isn't installed yet.

1. Noise is coming through the audio input.
   Power sources can add noise to the audio stream. Try connecting the Galicaster Mobile on a different plug. Do it with the monitor too. If the noise still remains you may use a Direct Injection Unite, commonly known as DI box.

1. Sound level is too low.
   After checking the sound level in the Sound Manager
   You should realize that depending on the input you are using, some have to get on "Line" level, a commom desktop microphone might not be the right device.
