This brings in support for compressed soundfonts (sf3) for Android.
We need libsndfile.so, but it has various dependencies (libogg, libvorbis,
libflac), which are somewhat annoying to build if you do everything
by yourself.
Fortunately cerbero has recipes for libogg, libvorbis and libflac.
I added custom recipe for libsndfile in the referenced cerbero fork, and
therefore the changes could be just in cerbero world.
Vorbis compressed SF3 samples are always loaded individually and stored
in the sample cache in uncompressed form. When dynamic-sample-loading is
not active (the default), then the uncompressed samples did not get
unloaded when unloading the SF3 font.
This fix makes sure that those samples are also freed. For bulk loaded
samples, the sample->data pointer is always the same as the
font->sampledata pointer. For individually loaded samples, the sample->data
pointer always points to a different memory region. So we can use that
information to determine if and when to unload the samples one by one.
Fixes#530Fixes#528
The old buffering code assumes that synth->cur is between 0 and FLUID_BUFSIZE.
However since fluid_synth_process() can render more than one buffer at a time
this isn't always true, and the new code handles other values properly.
Closes#527
This set of changes implements audio drivers for Android, OpenSLES and Oboe. The changes in the original sources are kept minimal so that it should be easily maintained.
When fluidsynth is run as a service using systemd, make sure
the service is considered started only when it is ready to process events.
In order to do so:
- Add an optional runtime dependency to libsystemd to the fluidsynth executable
- Change the systemd service type to "notify"
- Have fluidsynth notify systemd that the service is started after the server is started
- Have fluidsynth notify systemd that the service is stopping after joining the server thread
