* avcodec/adxenc: 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/adxenc: Mark encoder as init-threadsafeAndreas Rheinhardt2021-05-02

* 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/adxenc: Avoid undefined left shift of negative numbersAndreas Rheinhardt2020-01-21
| | | | | | | | | | Replace "((a << shift) + b) >> shift" by "a + (b >> shift)". This avoids a left shift which also happens to trigger undefined behaviour in case "a" is negative. This affected the FATE-tests acodec-adpcm-adx and acodec-adpcm-adx-trellis; it also fixes ticket #8008.

* avcodec: Add a min size parameter to ff_alloc_packet2()Michael Niedermayer2015-07-27
| | | | | | | | This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
