Re: One bug in the SVN and rtp wrapper issue
...to tell the
decoder which mode(NB/WB/UWB) is used
in the encoder. The RTP header don't contain the mode field and I don't
find the mode information in the
coded frame either.
Does this mean we have to use NB decoder in all cases?

No. Speex expects values in the +-32767 range, not +-1.0. Just
converting from int16 to float *is* the right thing to do.

Problem with the svn jitter buffer
...eex_jitter_get with high latency doesn?t works, I have
no sound.
Before this release, the speex_jitter_get works in all conditions.
speex_jitter_get return void, then I cannot know the reason of this problem.

problem with compression and decompression

Could you suggest a frequency which is more suitable? Please note, that the

Improving memory allocation

Does it have an option to enable C99? Otherwise, if you're aware of
another mechanism that allows it to allocate temporary stuff on the
stack, I might be able to support it.
