Wouldn't it be usefull go keep the "ac3" encoder using int16 and add the new one as "ac3_float" instead of breaking compatiblility with existing programms? -- Machs gut | http://www.iivs.de/schwinde/buerger/tremmel/ Manfred | http://packman.links2linux.de/ _______________________________________________ Packman mailing list [email protected] http://lists.links2linux.de/cgi-bin/mailman/listinfo/packman
