This is for me or for the whole community (if I'll ever get it working). I did find a message that said it's possible to use oss2jack, I havent't tried that, but off cause it would be nicer to have a native system. This would be _really_ cool. It would open a lot of new possibilities to the Cinelerra workflow! I wrote that email about oss2jack. With jack support, MacOS X[1] port could get accepted (since sound is the only important thing lacking, afaik) and Windows port would be easy too, as there is a jack version for windows[2] and X for windows and macosx. [1] - jack for macosx: http://www.jackosx.com/ [2] - jack for windows: http://www.grame.fr/~letz/jackdmp.html I'm seriously still thinking about implementing. Though I haven't got the hang of the system yet. Theres no commentation in the source! I would first implement the playback only. Though full Jack support would be nice. Could someone tell me where some writing to the audio device is done so I could understand the system better? ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

It would open a lot of new possibilities to the Cinelerra workflow! I couldn't quite figure out the sound architecture Cinelerra uses, the code isn't really documented that well! So I was hopeing some one could explain it to me. At a glance it seems that Cinelerra just creates desired audio class (ALSA, ESD etc.) (Where is this done?) and then probably writes in some buffer. This might cause problems with JACK though (callback architecture). The respective classes cinelerra/audio[alsa,esound,1394].C are instantiated in cinelerra/audiodevice.C I believe it would be great if Cinelerra would support JackTransport at some time in the future. Does anyone know how hard it would be to make Cinelerra slave to an external clock source? -- Adrian ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
