Don't worry if the process seems to hang at certain points: some libraries (like the RALF lossless format) are not available for our SYSTEM_ID, but one can live with them.

Splay is a minimal demo application supporting MP3s? (but not VORBIS), however madplay is far more efficient.

October 19, 2006, at 05:41 PM by Ettore -- How to convert your slug into a realaudio streaming radio
Added lines 1-39:

RealAudio format is still fully closed source, so there are no NDA-free projects supporting it. Although a reverse engineered codec is included in MPlayer?, it is based on floating point arithmetic and is not suitable for the FPU-less XScale? processor mounted on NSLU2.

The Helix project made available to the general public a fixed point codec and the Real streaming format handler, but only in binary form (a static library). The simplest command line player with audio stream support can be built in the following way.

NB: the binary library is available only in little-endian format, so your distribution must be LE too (e.g. debianslug).

NB2?: obviously you need a USB soundcard and proper ALSA drivers :-)

1) In order to correctly link to the binary library, your toolchain must be FPA based (which is the default for gcc 3.3 or older). For a debian host, you can for instance install the scratchbox packet scratchbox-toolchain-arm-gcc3.3-glibc2.3

2) Register and get (after a few hours) a valid login to access the non-restricted section of the Helix CVS server. Follow the instructions listed at https://common.helixcommunity.org/2004/devdocs/quickstart to correctly setup the build system.
