NAME FreeJ - vision mixer SYNOPSIS freej [ options ] [ streaming options ] [ layer files and video devices ] DESCRIPTION FreeJ is a vision mixer: an instrument for realtime video manipulation used in the fields of dance teather, veejaying, medical visualisation and TV. With FreeJ multiple layers can be filtered thru effect chains and then mixed together. The supported layer inputs are images, movies, live cameras, particle generators, text scrollers and more. All the resulting video mix can be shown on multiple and remote screens, encoded into a movie and streamed live to the internet. FreeJ can be controlled locally or remotely, also from multiple places at the same time, using its slick console interface; can be automated via javascript and operated via MIDI and Joystick. OPTIONS -h show commandline help -v show version information -D [ num ] set debug verbosity level to (1 to 3), default is 1 -s [ WxH ] set resolution to WidthxHeight, default is 400x300 -n start with all layers deactivated -c start without any interactive text console interface -j [ javascript.js ] run the javascript.js script file -e [ file.ogg ] set the filename of the local encoded ogg-theora movie (default is: freej.ogg), files already existing are not overwritten, instead filename-2.ogg is used; if a number is given, the corresponding file descriptor is used. To start/stop the recording and streaming use ctrl-w while running. FILES AND DEVICES FreeJ can run with an infinite number of layers, as much as your CPU can handle. Layer types are recognized from file extensions. Supported layers types include: movies (*.avi|*.asf|*.asf|*.wma|*.wmv|*.mov|*.mpeg) text (*.txt) depends from freetype library http://freetype.org cameras thru the Video4Linux device (/dev/v4l/*) images (*.png|*.jpg and more) flash animations (*.swf) only the vectorial animation is supported (flash v.3), no scripting nor streaming, but that's in FreeJ anyway ;) particle generator can be crated from commandline as layer_gen (or ctrl-g while running) to create a layer that doesn't needs any input, just draws nice particles any file type if not recognized will be threated as a text scrolling layer showing its contents scrolling them vertically on the screen EXAMPLES Scripting examples are available in the documentation, usually found locally in /usr/share/doc/freej and online on freej.dyne.org/docs/scripting For example this freej script will start a stream right away: // create a video encoder object - values [1-100] // video qlty video bit audio qlty audio bit encoder = new VideoEncoder( 10, 64000, 5, 24000); encoder.stream_host("giss.tv"); encoder.stream_port(8000); encoder.stream_title("testing new freej"); encoder.stream_username("source"); encoder.stream_password("2t645"); encoder.stream_mountpoint("freej-test.ogg"); register_encoder(encoder); encoder.start_stream(); // encoder.start_filesave("prova.ogg"); but be sure to actually play something in it: open a camera or movie layer. Don't stop reading documentation, this manual is not the only source of information.
