* opus_celt: deduplicate band quantization/dequantization functionRostislav Pehlivanov2017-12-041-0/+3
| | | | | | No point in having the same code twice to do exactly the same thing. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* opus: add an option to toggle intensity stereo phase inversionRostislav Pehlivanov2017-12-041-0/+2
| | | | | | | | | Due to a somewhat high volume of complains, phase inversion has been made optional with RFC8251. This allows for better bass frequency response when partially downmixing to play on systems with an LFE speaker. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* opus_celt: rename structures to better names and reorganize themRostislav Pehlivanov2017-02-141-14/+8
| | | | | | | | | | | | | | | | | | | | This is meant to be applied on top of my previous patch which split PVQ into celt_pvq.c and made opus_celt.h Essentially nothing has been changed other than renaming CeltFrame to CeltBlock (CeltFrame had absolutely nothing at all to do with a frame) and CeltContext to CeltFrame. 3 variables have been put in CeltFrame as they make more sense there rather than being passed around as arguments. The coefficients have been moved to the CeltBlock structure (why the hell were they in CeltContext and not in CeltFrame??). Now the encoder would be able to use the exact context the decoder uses (plus a couple of extra fields in there). FATE passes, no slowdowns, etc. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* opus_celt: move quantization and band decoding to opus_pvq.cRostislav Pehlivanov2017-02-141-10/+0
| | | | | | | | | | | | | | A huge amount can be reused by the encoder, as the only thing which needs to be done would be to add a 10 line celt_icwrsi, a wrapper around it (celt_alg_quant) and templating the ff_celt_decode_band to replace entropy decoding functions with entropy encoding. There is no performance loss but in fact a performance gain of around 6% which is caused by the compiler being able to optimize the decoding more efficiently.

| | | | | | | | | | | | | | The substreams can have different resampling delays, so an additional level of buffering is needed to synchronize them. Bug-Id: 876
