gstreamer sucks compositingfail i give up.

NOTES or in chronological order of discovery from first test to last test, first results on top to to last at bottom. i'm done player with gstreamer. 10moy2011 how i learned to use gstreamer. and how it sucks. this but ugly piping program is not intuitive in the least. I could not get gstreamer to save overlayed videos' i could display " picture in picture" but could not save pip to file. i give up on gstreamer.! my webcam is an old logitech v4lsrc webcam use v4l2src if your webcam is newer. debian/lenny: Working audio recording: $ gst-launch alsasrc ! audioconvert ! vorbisenc ! oggmux ! \ filesink location=output-sound.ogg ################################# /*********************** ****** ogm video *********** **********************/ debian/lenny remove videoscale for better rez.
