[Nico Sabbi CVS]

CVS change done by Nico Sabbi CVS

Update of /cvsroot/mplayer/main/libmpdemux
In directory mail:/var2/tmp/cvs-serv3719

Modified Files:
	muxer_mpeg.c 
Log Message:
simplification: don't use residual_buffer, but prepend remainder of current frame to next one (needed for future work; init frame->pos to 0 in reorder_frame();  fix: don't go beyond last frame in flush_buffer()
