  • This allows you to stream your desktop using vlc to another computer, in this case, 192.168.1.2 on your local network. If you have vlc installed, your all set to try this out. To view your own desktop, just run "vlc screen://" For more info, see http://nerdlogger.com/2008/01/08/stream-your-linuxwindowsmac-desktop-as-video-using-vlc/

  • the "delay" utility is an invaluable tool for me. with gnu-screen it allows you to schedule something and have it run and output to the current terminal, unlike "at". You can also use it like "sleep" with seconds and also with date: delay until 13:33 friday && echo test get it from: http://onegeek.org/~tom/software/delay/current/delay.c (author: Tom Rothamel)

  • This assumes that there is a 10.2 sec delay between the video and the audio (delayed). To extract the original video into a audio and video composites look at the command on extracting audio and video from a movie

  • Streaming HTML5 compatible video (Ogg Theora video with Vorbis sound) to an Icecast server using dvgrab, ffmpeg2theora and oggfwd. In this example I'm merging stereo sound to mono (-c 1), saving the original dv for later higher quality on-demand video (tee dvstream.dv), saving the theora stream for immediate on-demand video, and publishing the stream in Xiph's stream directory (-p and the name and description). The URL of the video will be (depending on your server) http://my.icecastserver.com/stream.ogv which will play in newer Firefox, Chrome and Opera web browsers. Cortado (a Java player) can easily be used for IE. Note also that I'm using port 80, which is not the default port for Icecast, this is to avoid restrictive firewalls. Also note that ffmpeg2theora 0.25 and will heed the bitrates much better than former versions because of using libtheora 1.1 or newer.
