h5. Computer Requirements

h6. 1.\- Which screen resolution should I use to run Galicaster?

Galicaster is prepared to run on 1920x1080, 1280x960 and 1024x768. Other resolutions may work but some visual defects may appear.

h6. 2.\- Should I use a tactile screen or can I use it with mouse and keyboard?

Tactile screens provide an easier, faster experience with Galicaster, but you can use it with a regular screen. Remember to activate the mouse pointer in the configuration file.


h6. 3.\- Which computer should I use?

Depending on the [Hardware recommendations], an Intel (R) i5 or equivalent should cover most of the capturing devices.

h5. Installation


h6. 1.\- Where should I install Galicaster?

You can install Galicaster anywhere, you won't need any extra space later since the recordings can be saved in other directory. Be aware that the installation folder, the repository folder and the devices will be accessed by the application so you have to set the permissions right.

h6. 2.\- Can I install Galicaster in other OS distributions?\\

For now, Galicaster has been tested only in Ubuntu 10.10, but we are working to make it available for newer versions of Ubuntu. If you try so yourself, please send us your findings or any issue you can solve.

h5. Devices

h6. 1.\- The recording preview does not start. What should I do?

Try activating the devices one by one. Once you have identified the problematic one, check it and its configuration.

h6. 2.\- The webcam freezes after a few seconds running.

Your computer is probably not powerful enough to handle the webcam video stream. Try stopping programs that could be affecting the webcam and lower its output resolution. Use _guvcview_ to identify which resolutions and frame rates are available for your webcam.


h6. 3.\- I can not hear anything in the preview.

Probably Galicaster is muted in the sound control of your operating system, or maybe the audio device you are using is muted or with a volume too low.

h6. 4.\- I can't hear anything in the recording.

Check if your audio device is muted or with too low a volume in the sound control of your operating system. Make sure your set the right device to record the audio from.


h6. 5.\- Galicaster is not getting any A/V signal from my laptop.

Make sure your laptop is sending the signal properly, then check your configuration, the capture device is probably misconfigured.
If you have further problems, make sure the laptop's screen resolution is compatible with you VGA frame grabber.

h6. 6.\- My camera is working fine but I only get noise or a black screen.

Your camera and your capture card should have a compatible configuration (e.g., both sending and getting a Video Composite signal in PAL). Also, check your camera configuration to ensure that it is actually sending data through the wire.

h6. 7.\- Galicaster was working fine until I restart the computer.

Two things could happen: The modules of one of your devices are not being loaded automatically or you are using a randomly created device.
In the first case, reload the modules manually or follow the driver instructions to load it permanently.
On the second case, please use UDEV rules to fix the devices source location on the computer.

Yes, they are erased permanently from your hard disk.


h6. 2.\- I want to ingest a recording but it will not work.

Review your ingest configuration carefully, make sure that your Matterhorn account is valid for digest authentication and check if your computer belongs to a network with access to the Opencast Matterhorn server you are trying to connect to.

h6. 3.\- The Matterhorn configuration seems fine but Galicaster doesn't connect to the server.

Remember to include the port in the host address and use a valid REST account, a user account won't work.

h6. 4.\- After making a recording with presenter and presentation tracks, both are shown on the same screen when I play it in Galicaster.

Make sure that {{conf.ini}} does not have two video tracks with the same flavor (video tracks are Hauppage, VGA2USB and v4l2).

h5. Usual launching program errors on 1.0.x

h6. 1.\- *Repository*

If the repository can't be loaded try to erase any of the last recordings you made, specially if the computer crashed or the power grid went off.

h6. 2.\- *iCalendar*
The newer version of iCalendar is not suitable for Galicaster 1.1.0 and previous ones, use iCalendar 2.2
