29394345af ALSA audio output experiment
I think it's smart to rather use ALSA directly instead of PortAudio.
ALSA is push AFAIK, and talking about it here at the hackspace, seems
like the better choice. It's a bit lower level, but anyway everything
speaks ALSA anyway. It's not like there's any reason to use PortAudio
at all. It's just an extra abstraction.

Coding for ALSA it'll also work with Pulseaudio and esd. Do people
really use other sound systems than Pulseaudio, esd or plain ALSA?
I can't think of it.

I really the idea about building a small tool first. I'll do that.

Also thought about making a small blikning cursor/text output, and
syncing a BEEP-sound to that, so that I can test around with throwing
in lots and lots of latency between "me" and the video, and try to
sync it anyway.

I should be able to read back from the sound card (or pulse audio
underneath, it will just work with alsa as the abstraction) how long
it takes for the bytes I'm pushing to reach the speakers, and do some
buffer tuning on that.

e64a17d1ba SConstruct: reduce the remaining defs

25b21fe575 reorder building/installing of Icons
no need to define them together with the source.
SCons is able to work out the real dependencies
just fine. Thus, Icons remain in Main SConstruct

c62eccd25f SCons overhaul/clean-up: disentangle main build
The goal is to make the build scrips more clear
at first sight. So move the main build targets
into a separate SConscript, to make them similar
to the tests, research and tools.

The final goal of this makeover is to reduce
the main SConstruct as much as possible

5cc034d26b refactor ScopedCollection to use an init() function 2012-01-07 04:44:48 +01:00
e6888f7b83 supplement direct support for populating by member function
this turns out to be the typical usage scenario
for ScopedCollection: a manager object owning
the collection will populate it with specially
crafted components and invoke a member function
for creating the individual components.

This shortcut avoids using tr1::bind alltogether

ce6fbe5f0f define how to pick the correct specialisation

be converted to string; everything else
just becomes a type id
