you get a framework by copying fileogg.h and .C to filempegps.h/C ... then you just throw out all ogg specific parts and put mpeg in... then you add all the necessary options to file.C/.h it should basically be the same thing ... have two different streams created by write_frames and write_samples (in ogg we can use internal stream implementation, you will probably have to write your own simple package queue) then you just rewrite flush_ogg with something that multiplexes mpeg-PS from those two streams.. probably using libavformat or something written by hand. Actually muxers usually have to work around player's quirks, so it is hard to write something absolutely robust. for OGG we needed quite some experts and a few iterations to get it right (thanks go out to j^ and mikes)... so if you can try to abuse libavformat, i haven't looked at it yet, so it might not be the blessing we count on ... if it is not... try to observe what other mpeg muxers do and copy & paste :) bye andraz _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
