I feel this is not a problem, since it's debian's gsm package which gets used, sorry. >> G726: >> * This source code is a product of Sun Microsystems, Inc. and is provided >> * for unrestricted use.

Well, the last release is from 1996, and there is no mention of copyright in all these files.

Anyway, the opal debian package uses system speex library, so everything is ok I suppose. >> gsm-amr: snoopy:~/softs/ekiga/opal-svn/plugins/audio/gsm-amr/src$ more >> amrcodec.txt >> This plugin implements an interface to the AMR-NB codec for OpenH323. >> >> For licensing reasons, the amr codec itself is not distributed with this >> plugin.

The same as above: I suppose they prefer to have it upstream because it opal is multi-platform and they need it for audio echo cancellation. Morover, they do not want to bother with licenses. Anyway, this is a good point. I was using amr from upstream instead of debian's one, I will change that. Conclusion: - I build with amr from debian (does it have features removed because of license or is it identical to upstream?) - gdm0610, speex and amr code from upstream will not get used, so no problem here - it remains the plugins 2 (g726) and 3 (lpc10), what to do with them? I see that twinkle has g726 support too. -- Eugen Dedu -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
