What is it? =========== A simple UDP based voice chat program. Currently we use libspeexdsp for its resampling capabilities and opus as the audio codec. There will also be ssl support in future versions. Why? ==== We basically need something that works well on many UNIX flavours. Skype is not really the answer to that. We also want something simple so that we can build on top of it. The plan is to create another program called ssvideo for video streaming. How to build ============ Simply `make' followed by a `make install'. If you are building with an unusual configuration please check the Makefile and the comments for what to do. How to use it ============= Pick one of the scripts already available and just pipe them over to sscall. For e.g. on OpenBSD: ./obsd/obsd-rec.sh | sscall 192.168.1.2 1234 4321 This will stream your voice to machine 192.168.1.2 on port 1234. Similarly on the other side you can connect on port 4321 on the local machine. Note that if you use anything else other than an 16kHz input sample rate, then you need to run sscall with the appropriate arguments so that it can downsample the stream. Similarly on the receive path if you use anything else other than 16kHz, then sscall will upsample to that sample rate. These options are generally useful if your system does not support certain input/output sample rates. Supported systems ================= - Linux - OpenBSD - FreeBSD - Solaris * It possibly works on other UNIX systems as well, we just have not had a chance to test yet. Acknowledgements ================ The people behind 2f30.org have been very helpful and their ideas have been much appreciated. You can find us on: irc.freenode.net #2f30
