pre-alpha_006 - we have gathered most of the pieces

So we have most of the pieces to make talkLock work now. On Blackberry, we can record audio, POST it to the webserver, which then fixes the audio data and base64 decodes it. For some reason the audio data (base64 encoded) loses "+" signs, they are replaced with spaces. Not sure if Apache or PHP does this. But anyway, talk.php (the webserver script side) fixes that. I can then GET the audio and it plays back :)

This is a BIG deal. This means that on Blackberry, I have everything I need to do communication.

I have fixed the code that allowed the audio handling to work on the LG CU500, which I found out is a Qualcomm based phone. However, the Blackberry cannot play audio from the LG, and the LG cannot play audio from the LG.

I think that to troubleshoot this I will take audio from the Blackberry, and audio from the LG, and feed them to ffmpeg to see what the difference is. I hate to make talkLock depend on ffmpeg compiled with amrnb support. That would make things a lot more complicated for folks to install the server side talkLock component. It makes me want to look at perhaps a different programming language for the server side. If Java knows about amrnb for example, then I could just use Java. We'll see.

Also ffmpeg doesn't have a lot of options to convert from amrnb to wav and back, but it has very good ogg support. So I might have to convert from amrnb to ogg to wav, and make all audio that is fetched from the server wav. That is a big hammer for a small nail though.

But we have all of the pieces! Time to hack up a demo option to do two-way communication on Blackberry ;)
