* avcodec/mpegvideo: Allocate map and score_map buffers jointlyAndreas Rheinhardt2022-10-29
| | | | | | Reduces the amounts of allocs, frees and allocation checks. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/snow: Move initializing MotionEstContext to snowenc.cAndreas Rheinhardt2022-10-12
| | | | | | | Only used by the encoder. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/internal: Move ff_get_buffer() to decode.hAndreas Rheinhardt2022-08-27
| | | | | | | | | Only used by decoders (encoders have ff_encode_alloc_frame()). Also clean up the other headers a bit while removing now redundant internal.h inclusions. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/snow: Remove unused halfpel_planeAndreas Rheinhardt2022-07-31
| | | | | | | Committed in 5be3a818719d613e2f225cf1532fda01ba106b04 in an unfinished state; never used or finished and always disabled. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* lavc/encode: add an encoder-specific get_buffer() variantAnton Khirnov2022-05-11
| | | | | | | | | | | Several encoders (roqvideo, svq1, snow, and the mpegvideo family) currently call ff_get_buffer(). However this function is written assuming it is called by a decoder. Though nothing has been obviously broken by this until now, that may change in the future. To avoid potential future issues, introduce a simple encode-specific wrapper around avcodec_default_get_buffer2() and enforce its use in encoders.
* lavc/snow: only allocate mconly_picture for decodingAnton Khirnov2022-05-11
| | | | It is not used in the encoder.
* avcodec: Remove unnecessary h263.h inclusionsAndreas Rheinhardt2022-01-09

* Replace all occurences of av_mallocz_array() by av_calloc()Andreas Rheinhardt2021-09-20
| | | | | | | They do the same. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/snow: Hardcode table to save spaceAndreas Rheinhardt2021-05-02
| | | | | | | | The size of ff_qexp is only 32 bytes, but the code to generate it at runtime takes 47 bytes (GCC 9.3, x64, -O3 in an av_cold function); so just hardcode it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/snow: Use ff_thread_once() in ff_snow_common_init()Andreas Rheinhardt2020-12-10
| | | | | | | | | | | | ff_snow_common_init() currently initializes static data every time it is invoked; given that both the Snow encoder and decoder have the FF_CODEC_CAP_INIT_THREADSAFE flag set, this can lead to data races (and therefore undefined behaviour) even though all threads write the same values. This commit fixes this by using ff_thread_once() for the initializations. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPATDerek Buitenhuis2016-01-27
| | | | | | | | | | Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
