Using CELT on iPod
...ELT 0.7.1 on an iPod touch and it seems we are already reaching the CPU limit of the machine for a 1 channel both directions stream. The CELT README says that the code should be compiled with fixed-point support, but it it not clear how it has to be used later on. We currently use celt_encode_float/celt_decode_float functions. Can we still use them with the fixed point version of CELT?
Anny other advice to improve the CPU use issue? (size of the encoded packet, frame rate... etc...)
Thanks

Encoder crash in multithreading processing
Hi, I try to work with CELT encoder & decoder in 2 different threads at the
same time.
So I create/destroy encoder and encode in one thread and create/destroy
decoder and decode in other thread.
If I didn't protect celt_encoder_create, celt_encode_float and
celt_decoder_create, celt_decode_float with CRITICAL_SECTION
I get stable error in icwrs32 or ec_byte_write1 (more often) in encoder.
What does it mean ? Is CELT not thread-safe ? Any way to avoid this error
except CRITICAL_SECTION ?

ps: I use last version from git repository, but I also checked with previous
version and with...

[PATCH] Moved the application of the pitch gain to (un)quant_bands(). This doesn't change anything to the codec, but will make the next changes easier.
