CELT in ffmpeg and API questions
...here that support for decoding using libcelt
was just pushed to ffmpeg.
It raised a few API questions or issues:
* At least while it's experimental, having a constant in the library for the
supported bitstream version would probably be useful. Something like that
comes to mind:
extern celt_int32 celt_bitstream_version;
or, even better:
int celt_bitstream_version_supported(celt_int32 version);
Since dynamic linking is supported, a build-time constant is not suitable.
Currently, I resorted to have libcelt generate a dummy header to get the
version_id field.
* The header_size i...

V0.8.0 Problems
Tim, et al,
I have run into several problems with V0.8.0. I will address them seperately.
1. My compiler is complaining about the following code in celt.c which seems to define metric first as celt_word32, then as celt_word16. Am I mis-interpreting something?
?? VARDECL(celt_word32, metric);
?? ALLOC(metric, len, celt_word16);
Thx

API Change
Hi everyone,
I've just changed the API for CELT, but at least there's a good reason
for that. It's now possible to use the same mode data for both mono and
stereo. So here's the change:
- The celt_mode_create() function has a "channels" parameter
- The celt_encode_create() and celt_decoder_create() functions now have
an additional "channels" parameter.
- I

question about CELT_SET_COMPLEXITY_REQUEST
...e for celt_encoder_ctl in 0.7.1 I'm confused as to why
Complexity is described as a value from 0-10, but the code only appears to
have one setting for 0-2 and another setting for 3-10. Is that for future
use or am I missing something?
case CELT_SET_COMPLEXITY_REQUEST:
{
int value = va_arg(ap, celt_int32);
if (value<0 || value>10)
goto bad_arg;
if (value<=2) {
st->pitch_enabled = 0;
st->pitch_available = 0;
} else {
st->pitch_enabled = 1;
if (st->pitch_available<1)
st->pitch_available = 1;
}
}

Modes?
...and 128 byte frames, but get NULL
returned from the celt_mode_create function. I am not defining
CUSTOM_MODES_ONLY (because I don't know what it means). On the last couple
of lines of code, there is no error (error=0), but it appears that you
always return NULL..?

fixed point code

Could you provide us with fixed-point code for initialization of this array? Or you may kindly provide us with ROM tables of the array for each possible combination of frame size and sampling freq...?
