Steps to build the MPlayer-1.0rc2:

Download and install the cross toolchain gcc version 4 for Linux 2.6.

$ cd /opt
$ tar xjf mipseltools-gcc412-glibc236-lnx26.tar.bz2
$ export PATH=/opt/mipseltools-gcc412-glibc236-lnx26/bin:$PATH

Download the mplayer-1.0rc2-jz47-yyyymmdd.tar.bz2 tarball and unpack it:

$ tar xjf mplayer-1.0rc2-jz47-yyyymmdd.tar.bz2

For linux platform building:

$ ./build.jz47 JZ4755	(JZ4755 base board)
$ make

or 
$ ./build.jz47 JZ4750	(JZ4750 base board)
$ make

or 
$ ./build.jz47 JZ4740	(JZ4740 base board)
$ make

For playing
1) Normal playing
   ./mplayer a.avi

2) Analysis the video decoder performance
   ./mplayer -nosound -benchmark a.avi

3) Resize the video output size and specify the start point
   ./mplayer -xpos 12 -ypos 12 -vf scale=320:240 ./a.avi

4) Dynamic resize the video output size and specify point
   ./mplayer -slave a.avi
   video 12 12 320 240
   video -1 -1 -1 -1

   x,y (-1, -1) is center display
   w,h (-1, -1) is self-adapting
