Mathieu,
Do you remember why we added this portaudio init/cleanup sequences ?
I remember this was about the sharing of portaudio devices between phapi and
the core NG but I don't remember the exact use case that was leading to a
problem.
The problem is that If the application does PA_Initialize and then phapi
does PA_Intialized it creates problems.
Maybe the best solution would be to add to a phApi a call
phAudioInit()/phAudioCleanup() which will handle multiple invocation issues.
Or a call phEnumerateAudioDevices(bool enumInputDevs, bool enumOutputDevs,
void (*callback)(const char *devid, enum { IN,OUT,IO } kind, const
char *displayName, void *cbkData),
void *cbkData);

Hi,
I noticed that at http://www.portaudio.com/download.html there is a
release of portaudio_v19 tagged as stable, so a sync could be
interesting. :)
I built .deb packages of this release for Ubuntu edgy. They are here
http://netgroup.polito.it/~cavedon/portaudio/ if someone wants to test
them.
I used the control structures from the .deb of feisty, and installed
them in my pc; they seems to work ok with wengophone.
Secondly, I noticed that wengophone is continuously reinitializing the
portaudio library. So I attached to patch to ticket #1212, so as to have
only one call to Pa_Initialize and Pa_terminate.
I can see the speed improvement.
But do you think this can lead to problems?
Regards,
Ludovico
