Dieses Skript erleichtert das Betrachten und Aufnehmen mit dem USB Audio- und Videograbber EasyCAP DC60. Vor dem Start des Betrachter- bzw. Aufnahmeprogramms führt es noch einige Tests durch. Das Ergebnis wird im Programmauswahlfenster oben angezeigt.

Damit es funktioniert muss das Paket Zenity und mindestens eines der Betrachterprogramme vlc, mplayer, tvtime oder cheese und mencoder für die Aufnahme installiert sein.

#  Date: 08.03.2012
#  The first part of the script is based on the test scripts by Mike Thomas coming with the easycap driver source
#  http://sourceforge.net/projects/easycapdc60/, 
#  the second part (recording section) is mainly the same than in the previous version of this script.
#  The ascii artwork is based on a template i found here: http://www.retrojunkie.com/asciiart/electron/tv.txt

Installation

Um das Skript nutzen zu können, muss es nach dem Download noch mit dem Befehl

chmod a+x easyview-n-cap-0.9.sh 

ausführbar gemacht werden. Anschließend kann es in einem Terminal oder einfach durch einen Doppelklick gestartet werden. easycap_script_menu.png

Einstellungen im Skript

Im oberen Bereich des Quelltextes können einige Parameter die die Videoquelle betreffen voreingestellet werden, dazu muss das Skript in einem Editor bearbeitet werden. Wenn die Variable

1
verbose=0

auf 0 gestellt ist, werden einige Statusmeldungen nicht angezeigt.

Nutzung

Nach dem Start des Skripts werden einige Auswahldialoge zur Einstellung des Video- und Audioeingangs angezeigt. Dann öffnet sich das Programmauswahlfenster (siehe Bild). In oberen Bereich zeigt dieses die eingestellten Parameter. Im unteren Bereich kann in einer Liste eines der installierten Betrachterprogramme ausgewählt werden. Wird mencoder gewählt, dann öffnen sich einige weitere Dialoge in denen die Aufnahmeeinstellungen angegeben werden.

Logfile

Das Skript erstellt zu Diagnosezwecken in dem Ordner in dem es gespeichert ist ein Logfile in das die Statusmeldungen des vom Skript aufgerufenen Betrachterprogramms geschrieben werden.
