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.

h3. 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:

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

* 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. More information about this matter is available [here|Galicaster: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

{anchor:hau}
h4. 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:

{code:none}
v4l2-ctl -d /dev/haucamera --list-standards | grep Index -A 2
v4l2-ctl -d /dev/haucamera -s 0
{code}

*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}
v4l2-ctl -d /dev/haucamera -n | grep Input -A 1
v4l2-ctl -d /dev/haucamera -i 2
{code}

Inputs 1 and 3 are for 4-pin.

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

Add this section in the _conf.ini_ file.

{code:none}
[audio]
min = -60
max = 0
{code}

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 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:

{code:none}
host = http://fakeadmin.matterhorn.com:80
{code}

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.

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:

{code:none}
workflow = full
workflow-parameters = trimHold:true
{code}

If you set up more than one parameter:

{code:none}workflow-parameters = trimHold:true;captions=True{code}

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:

{code:none}
[ingest]
active = True
default = False
host = http://fakeadmin.matterhorn.com:80
username = matterhorn_system_account
password = CHANGE_ME
workflow = full
