No, it has nothing to do with performance. Xine ships with its own version of ffmpeg built in. You can tell it to use that, or the system's version of ffmpeg.
The latter is typically used, but in the case of dapper the system's ffmpeg is somewhat old, and we might get better result with the built-in ffmpeg. The only problem(s) are: (1) requires a source-change. Not impossible, a core-dev can do that. (2) Could introduce bugs because I don't think the internal ffmpeg went through much testing in Ubuntu. -- Old xine-lib causes crash in xine-based media players https://launchpad.net/bugs/63304 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
