I realize the video capturing the area of the applet with XVidCap Screen Capture (software for Ubuntu) and I add the soundtrack using mencoder.
To install it, I run the following line(2) in the console:
sudo apt-get install mencoderAnd now I run this line(2) in order to add Clouds over us to the video generated by XVidCap:
mencoder test.mpeg -o video01.avi -ovc copy -oac mp3lame -audiofile music.mp3I also realize a video without sound (see on YouTube). In this case first of all I install mplayer(3)
apt-get install scrot mplayerand after I start the screen capture procedure(3):
while [ 1 ]; do scrot -q 100 $(date +%Y%m%d%H%M%S).jpg; sleep 1; doneIn this case I capture the entire screen, so before the realization of the video, I must extract from about 100 images the portion of the sky. In order to complete this operation without mistakes I install the David's Batch Processor(4), a GIMP's plugin. After the resize, I list all files in a txt(3)
ls -1tr *.jpg > files.txtand produce the video(3)
mencoder -ovc x264 -mf w=900:h=600:fps=8:type=bmp 'mf://@files.txt' -o video02.aviRemember: all lines must run in the fold of the images. In alternative you must write the complete path of files.
