Subject: [Speex-dev] writing issues on arm build !
I am a student writing a voip program on ppc for a project for school.
Before I explain my issue, let me apoligize for being extremely newbie :(
Here's the situation:
I am using the ARMV4 release build from the speex website. Right now I am
simply trying to make an encode function using speex that will take an
unsigned char* of raw wav data (8000 samples, 8 bits / sample, mono) and
encode it using speex, and have speex write it somewhere so I can do..
whatever with it.
Simple ? I thought it would be :P
The main issue I am having right now that is stopping me, is my program
execution will never get past speex_bits_write.. speex_encode works fine but
speex_bits_write blocks forever and my program simply hangs. If this is a
common issue please let me know and I'll be on my way :)
The only thing is, to be honest.. based on the documentation and the manual,
I can't seem to fully grasp what I need to set up to properly use speex
(maybe I'm too used to the nice javadocs :P ) Looking at the sample code
(sampleenc.c/sampledec.c) it looks very simple, but judging by the API
theres a lot of settings I can change. For the type of raw data I have (8000
samples, 8bps etc).. do I need to change settings within speex before I
begin encoding ? Not including turning on VAD and whatnot....
I guess a simpler question for me to ask, to build this simple function that
takes raw data and encodes it into speex, what steps to I need to take in
terms of converting my unsigned char* buffer to anything before passing it
into encode ? If someone can simply help me with that function (give me a
rough outline no code or anything :P ) I think I can get a better idea about
speex and figure out the rest myself .
Thank you very much to anyone who helps me i REALLY appreciate it!!!
