* avcodec/dcaenc: Avoid copying packet data, allow user-supplied buffersAndreas Rheinhardt2021-05-05
| | | | | | | | When the packet size is known in advance like here, one can avoid an intermediate buffer for the packet data by using ff_get_encode_buffer() and also set AV_CODEC_CAP_DR1 at the same time. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/dcaenc: Don't write one bit at a timeAndreas Rheinhardt2021-05-05

* 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.

* dcaenc: cleanup on init failure and add a threadsafe init codec capRostislav Pehlivanov2018-01-13
| | | | | | | | | The encoder didn't clean up if a malloc failed during init. It also doesn't need any external tables to be initialized on init. Finally, it didn't need to check for whether avctx->priv_data exists during uninit. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* avcodec/dcaenc: Do not abort process in case of bitrate deficitDaniil Cherednik2017-05-16
| | | | | | | | | | | | Old behaviour - abort if at least one subband has 1bit quantizer and consumed_bits still greater than frame_bits size. It was a bit strange - we still could reduce bits consumption by reducing SNR for other subbands. Same strange logic with upper threshold - stop bits allocation if at least one subband reach 26bits. New behaviour - if consumed_bits greater than frame_bits and all subbands has 1 bit quantizer we restart bits allocation and allow zero subbands.

| | | | | | | | | | | The idea is to use ffmath.h for internal implementations of math functions. Currently, it is used for variants of libm functions, but is by no means limited to such things.
