Open Sound System, a
cross-platform low level audio API for accessing analog audio devices.
This is the de-facto standard audio API for Linux until kernel 2.4.
ALSA
Advanced Linux Sound Architecture,
a more advanced low level audio API. This is the de-facto standard
audio API for Linux since kernel 2.6.
GTK+
The GIMP Toolkit, a cross-platform
graphical user interface API.
Discussion
Among the software components listed above, OSS, ALSA and GTK+ are
industry standard, and are straightforward to use. But the Helix Client
Library is a special library, the open sourced version of Real
Network's streaming libraries.
Tests were made to make sure Helix indeed compiles and runs fine on the
target platform. All libraries where successfully compiled and SMIL
playlists were successfully played. For this, the splay command line
sample program was used, which is part of the Helix codebase. For
compiling helix client libraries, refer to the Getting
Started with the Helix Sources pages. The settings used for
successful compilation:
[0] Set BIF branch (hxclient_1_3_0_neptunex)
[1] Set Target(s) (splay)
[2] Set Profile (helix-client-all-defines)
[3] run: build
[4] Toggle make depend & makefiles (-e -n)
[5] Toggle release (-trelease)
[6] Toggle 'make clean' (-c)
[7] Toggle clobber (Dangerous!) (-C)
[8] Toggle halt-on-error (-p green)
[9] Toggle verbose mode (-v)
[10] Toggle static build (-tnodll)
[11] Checkout source for selected target now
[12] Set Tag/Branch/Timestamp
[13] Help Page (full help in build/doc/index.html)
[14] run history: build
[Q] Quit
