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_s...

Opus approved by the IETF
...n, we'll be replacing the use of the CELT name with Opus and I'd
like to encourage everyone to switch to Opus in their applications. Note
that Opus can do everything that CELT could, so this should not be
causing major problems beyond updating to the new API (mostly a matter
of changing the celt_ prefix to opus_).
Cheers,

[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.
