Mplayer playback gets stuck

[arthurchiu@…]

I have cross-compiled MPlayer for a mips32 linux 2.4 machine using an x86 linux
2.6 machine. The configure command I ran is:

./configure --cc=mipsel-linux-gcc --host-cc=mipsel-linux-gcc
--as=mipsel-linux-as --target=mips
--with-extraincdir=/home/mediadev/Arthur/blackWidow/libmad-configure/usr/local/include:/home/mediadev/Arthur/blackWidow/opt/toolchains/uclibc-crosstools-2.4.3/include:/home/mediadev/Arthur/blackWidow/opt/toolchains/uclibc-

--disable-cdparanoia --disable-sortsub --disable-vidix --disable-tga
--disable-pnm --disable-md5sum
--with-livelibdir=/home/mediadev/Arthur/blackWidow/live-mips/live
--with-madlibdir=/home/mediadev/Arthur/blackWidow/libmad-configure/usr/local/lib

When I make it, I compiled the codec-cfg with x86 version of gcc first, get the
output codecs.conf.h by ./codec.cfg ./etc/codecs.conf > codecs.conf.h, then type
make again. I also added -shared-libgcc in config.mak to resolve a hidden symbol
error on the very last step of the compilation.

Now, with the compiled mplayer executable, I moved it to the mips machine and
tried to run it and test it with a music file. The executable ran, but I have
problems playing the file. I play the file using the following command and the
log with -v option gives:

At this point, the music got "stucked" between -0.2 and 0.2, ie, keep looping
back and forth between this point.
A: 0.2 (00.2) ??,?%
I used the -softsleep option because I can't find /dev/rtc or /proc/sys/dev/rtc
in my mips system. I looked in the code and found out that the ??,?% should be a
number indicating the CPU usage. Sometimes, it is not ??,?% but instead it goes
to 2000% to 3000%. Would my slow CPU (it's a mini embedded system) have caused
this?

The audio_setup: frags looks quite suspicious too. Though I'm not too sure what
the frags mean, but when I look online, everyone have a large bytes / frag
number where as I am only getting 4 bytes / frag.

I then tried compiling Mplayer with the same configuration options (without all
the cross compilation selections). I can play the same song without a problem on
my x86 machine. The following is the log for that:

The song plays very smoothly after. The CPU usage remains around 1.5% and the
bytes / frag is much higher. What might have happened? How come the music won't
play properly on the other system? Any help would be very much appreciated.
Thanks a lot.

Cheers,

well obviously the problem is that the first mplayer output says 'mp3lib: using generic C decore!' while the second mplayer output says 'mp3lib: made decode tables with MMX optimization mp3lib: using MMX optimized decore!'.

mmx is faster than the c version.

probably you need to use an interger-only mp3 decoder on your mips box, like libmad.

-ac mad (if you compile with libmad)
