h6. 4.\- Config galicaster
The values are in the file conf.ini
Sections:
* basic
** repository: path to the working folder.
** admin: enables admin mode (True\|False)
Example:
{code}
[basic]
repository = /mnt/videos/Repository
admin = True
{code}
* screen
** right: Name of the video device to be shown in the right screen (None to deactivate).
** left: Name of the video device to be shown in the left screen (None to deactivate).
** cursor: Shows or hides the cursor. (True\|False)
Example:
{code}
[screen]
right = Epiphan
left = Hauppagge
cursor = True
{code}
* ingest
** The data to connect Galicaster to an Opencast-Matterhorn server.
{code}
[ingest]
default = True
username = matterhorn_system_account
host = http://admin.matterhorn.es:8080
password = CHANGE_ME
workflow = full
{code}
* track
** Values common to all devices:
*** name: Name assigned to the device.
*** device: Tipo de dispositivo. (v4l2\|vga2usb\|webcam\|hauppage\|pulse)
*** flavor: Matterhorn "flavor" associated to the track. (presenter\|presentation\|other)
*** location: Device's mount point in the system (p.ej. /dev/video0).
**** For PulseAudio devices run:
{code}
$ pactl -list | grep "Source" -A 5
{code}
and use "Name:" as the "location" field.
*** file: The file name where the track will be recorded.
*** active: Whether the device will be played and recorded. (True\|False)
** Values in audio (pulse) devices:
*** playing: Indicates if the audio, apart from being recorded, is played. (True\|False)
*** vumeter: Activates data sending to the program's vumeter. (True\|False) Only one device should be activated.
*** amplification: Gstreamer amplification value: < 1 decreases and > 1 increases volume. Values between 1 and 2 are commonly used.
