mp3 decoder for AM335

DJ-NG

Hi champs,

Custumer is looking for a mp3 decoder, running under linux bsp, to include entertainment audio in main application.

Any ideas ?

Thanks!

enable optimizations while compiling and configuring; so the extended instruction set offloads the CPU.

add this options with your CFLAGS: -mfpu=neon

and these options while configuring:

--with-cpu=neon --enable-network=yes --with-audio=alsa --with-default-audio=alsa --enable-modules=no --with-optimization=4

CPU utilization is nearly 0% :-)

Best regards,

Wim
