That configuration is certainly supported.
Yet another (and I'm trying it now), would be to have both the native and libfaac/libfaad enabled (Windows and OSX). It may be possible to present both options to the user. It's certainly possible via the ffmpeg command, but via the custom ffmpeg options dialog, it gets a bit confusing (read that as if I'd said "I haven't figured it out yet". :-)) The first option is definitely possible though...well, I'll be testing it in a few minutes anyway. :-) Leland -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/602934 Title: ffmpeg import/export not working with ffmpeg version in maverick -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
