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. = Quelltext = Download des Skripts: [[Anhang(easyview-n-cap-0.9.1.sh easyview-n-cap-0.9.1.sh)]] {dl} {{{#!code bash #!/bin/bash # # easyview-n-cap.0.9.1 by andlandl (http://wiki.ubuntuusers.de/EasyCAP_DC60_USB_Audio_und_Videograbber/Easycap_Skript) # 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 # For more information view # http://easycap.blogspot.com # Contact: easycapdc60-blogspot@yahoo.de #----------------------------------------------------------------------------- # # Basic options # # preselect parameters for viewing/ capturing # change these parameters according to your needs #----------------------------------------------------------------------------- VERBOSE=1 # if '0', this script does not show messages window and does not ask for norm and input number anymore NORM="PAL" # preselect tv norm 'PAL' or 'NTSC' INPUT_NR=0 # preselect input number of your easycap where video source is plugged in input_width=720 # preselect width an height of video source (mplayer, vlc, mencoder) input_height=576 # other possible combinations: 640/480; 320/240 ASPECT=169 # '169' (16:9) or '43' (4:3); this value affects video playback with mplayer or vlc only! #----------------------------------------------------------------------------- #----------------------------------------------------------------------------- MESSAGE=() R_MESAGE=() EXITCODE=0 #----------------------------------------------------------------------------- #----------------------------------------------------------------------------- # frequency check # # Requires that precisely one EasyCAP is plugged in. #----------------------------------------------------------------------------- MANY=`2>/dev/null lsusb -v -d 05e1:0408 | grep tSamFreq | wc -l ` if [ "x" = "x${MANY}" ]; then MESSAGE=("${MESSAGE[@]}" "\nERROR: cannot count 05e1:0408 EasyCAPs") EXITCODE=1 # # exit 1 fi if [ "0" = "${MANY}" ]; then MESSAGE=("${MESSAGE[@]}" "\nERROR: No 05e1:0408 EasyCAP found.

Anschließend kann es in einem Terminal oder einfach durch einen Doppelklick gestartet werden. [[Bild(easycap_script_menu.png, 200, right) ]] = 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 {{{#!code bash 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.
