* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

* avcodec/opusdec: Return error upon errorAndreas Rheinhardt2020-12-31
| | | | | | | | | The Opus decoder forgot to return an error when allocating an SwrContext fails. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/opusdec: Remove always-true checkAndreas Rheinhardt2020-12-31
| | | | | | | | The celt_delay AVAudioFifo is always allocated during init, so checking for its existence in .flush is unnecessary. Reviewed-by: Lynne <dev@lynne.ee> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec: set AV_CODEC_CAP_CHANNEL_CONF on decoders which set their own channelsHendrik Leppkes2020-12-10
| | | | | | | | | | | | The decoders in this set either have a fixed channel count, or read it from the bitstream, and thus do not require the channel count as external information. Fixes various regressions since 81503ac58a763a36b1f57264013b1e76acb62b68, which requires a valid channel count for decoders which do not set this capability.

* 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>

* 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>
