* avcodec/opus: Rename opus.c->opus_celt.c, opus_celt.c->opusdec_celt.cAndreas Rheinhardt2022-10-09
| | | | | | | | | | Since commit 4fc2531fff112836026aad2bdaf128c9d15a72e3 opus.c contains only the celt stuff shared between decoder and encoder. meanwhile, opus_celt.c is decoder-only. So the new names reflect the actual content better than the current ones. Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/opus: Move defines to better placesAndreas Rheinhardt2022-10-05
| | | | | | | | | Move ROUND_MUL* macros to their only users and the Celt macros to opus_celt.h. Also improve the other headers a bit while at it. Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* opus: convert encoder and decoder to lavu/txLynne2022-09-26
| | | | | This commit changes both the encoder and decoder to use the new lavu/tx code, which has faster C transforms and more assembly optimizations.
* opusdsp: adjust and optimize C function to match assemblyLynne2019-09-11
| | | | | | | | | | | | | | | | | | | | | The C and asm versions behaved differently _outside_ of the codec. The C version returned pre-multiplied 'state' for the next execution to use right away, while the assembly version outputted non-multiplied 'state' for the next execution to multiply to save instructions. Since the initial state when initialized or seeking is always 0, and since C and asm versions were never mixed, there was no issue. However, comparing outputs directly in checkasm doesn't work without dividing the initial state by CELT_EMPH_COEFF and multiplying the returned state by CELT_EMPH_COEFF for the assembly function. Since its actually faster to do this in C as well, copy the behavior the asm versions use. As a reminder, the initial state 0 is divided by CELT_EMPH_COEFF on seek and init (just in case in the future this is changed, its technically more correct to init with CELT_EMPH_COEFF than 0, however when seeking this will result in more audiable pops, unlike with 0 where the output gets in sync over a few samples).

* opus: add an option to toggle intensity stereo phase inversionRostislav Pehlivanov2017-12-04
| | | | | | | | | 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>

| | | | | | | | | | | This decoder-side change, introduced in RFC 8251 (section 9), slightly improves the decoded quality of 16kbps speech in Hybrid Mode.

* opus_celt: rename structures to better names and reorganize themRostislav Pehlivanov2017-02-14
| | | | | | | | | | | | | | | | | | | | 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 Pehlivanov2017-02-14
| | | | | | | | | | | | | | 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.
