It is very hard to divide mplayer code from xplayer in a short period for ASL (even if we done, xplayer is non-functional). So xplayer is a vital issue that we need discuss in detail. Is it obligatory to commit xplayer code into ASF repository at present? xplayer is just one application software kit of Bluesky that includes three independent system, real-class system (developed by c++), MERSMP and xplayer. 2008/7/9, Ting Peng : > > On Wed, Jul 9, 2008 at 2:41 PM, Bernd Fondermann < > bernd.fondermann@googlemail.com> wrote: > > > On Wed, Jul 9, 2008 at 1:50 AM, Ting Peng wrote: > > > Dear all, > > > > > > Our xplayer has synchronization work for the played media objects.
