Re: [GtkGLExt] capturing video clips

["Karl Ostmo" <kostmo purdue edu>]

In OpenGL, you can capture individual frames to image files using
glReadPixels, then use ffmpeg to encode the frames to an .mpg file.  I
think ffmpeg likes the input files to be JPEG, so if you have a
sequence of .png files, for instance, you can batch convert them with
ImageMagick:

mogrify -format jpg *.png

ffmpeg -i input_image%03.jpg output_movie.mpg
