How send audio/video data over the net? ======================================= Just some pointers where to look. I haven't tried everything myself. still images (webcam) --------------------- You can use the xawtv's webcam utility (in the webcam subdirectory) to capture single frames and upload them to a (web-)server using ftp. There are plenty of other tools for that purpose, http://freshmeat.net has a list. both audio and video -------------------- You can use video conferencing tools, see http://www.openh323.org. That should even interoperate with M$ Netmeeting. I've heard there is a project named "gnomemeeting" ... You might want to have a look at videolan (http://www.videolan.org). Using the mbone tools (i.e. vic for video, vat or rat for audio) works too, see http://www-mice.cs.ucl.ac.uk/multimedia/software/ Drawback is that these two work independent of each other, that's why there is no way to make audio and video sync properly. video only ---------- xawtv works with a remote display. Eats plenty of network bandwith as the X11 protocol is not optimized for streaming video. Can be used to max-out ATM cards. Don't even think about it with something slower than Ethernet. audio only ---------- Use some network sound daemon, esound for example: sox -w -c 2 -r 44100 -t ossdsp /dev/dsp -t raw - | esdcat -r 44100 Check out http://freshmeat.net, IIRC there are some tools to multicast audio data.
