2022-03-16configure: Use a separate config_components.h header for $ALL_COMPONENTSMartin Storsjö
This avoids unnecessary rebuilds of most source files if only the list of enabled components has changed, but not the other properties of the build, set in config.h. Signed-off-by: Martin Storsjö <martin@martin.st>

2020-12-08avcodec/aactab: Make AAC encoder and decoders actually init-threadsafeAndreas Rheinhardt
Commit 1a29804558c13ef512d9ef73a9b0d782af4fa5f2 guarded several initializations of static data in the AAC decoders with an AVOnce and set the FF_CODEC_CAP_INIT_THREADSAFE flag, believing the former to be sufficient for the latter. It wasn't, because several of these static tables are shared with other components, so that there might be data races if they are initialized from multiple threads. This affected initializing the ff_sine_* tables as well as initializing the ff_aac_pow*sf_tab tables (shared between both decoders and encoder) as well as ff_aac_kbd_* tables (shared between encoder and floating point decoder). Commit 3d62e7a30fa552be52d12b31e3e0f79153aff891 set the FF_CODEC_CAP_INIT_THREADSAFE flag for the AAC encoder. More explicitly, this commit used the same AVOnce to guard initializing ff_aac_pow*sf_tab in the encoder and to guard initializing the static data of each decoder; the ensuing catastrophe was "fixed" in commit ec0719264cb9a9d5cbaf225da48929aea24997a3 by using a single AVOnce for each codec again. But the codec cap has not been removed and therefore the encoder claimed to be init-threadsafe, but wasn't, because of the same tables as above. The ff_sine_* tables as well as ff_aac_pow*sf_tab tables have already been fixed; this commit deals with the ff_aac_kbd_* tables, making the encoder as well as the floating-point decoder init-threadsafe (the fixed-point decoder is it already).

2020-12-08avcodec/aacdec, aactab: Move kbd tables to their only userAndreas Rheinhardt
The floating point kbd tables for 120 and 960 samples are only used by the floating point decoder whereas the fixed point kbd tables for 128 and 1024 samples are only used by the fixed point AAC decoder. So move these tables to their only users. This ensures that they are not accidentally used somewhere else without ensuring that initializing these tables stays thread-safe (as it is now because the only place from where they are initialized is guarded by an AVOnce).

2020-11-24avcodec/aac*: Make initializing ff_aac_pow*sf_tab thread-safeAndreas Rheinhardt
This table is currently initialized up to three times: Once by the encoder and twice by the decoders (once by the fixed and once by the floating-point decoder); each of these initializations is guarded by an AVOnce, yet the fact that there are three of them implies that there might be data races (the fact that each entry is only written to once (to its final value) when initializing means that this is safe in practice, yet it is still undefined behaviour). Fix this by only initializing the table from one place that is guarded by a single AVOnce. This also avoids unnecessary duplications of the init code.

Since the ff_aac_tableinit() can be called by both the encoder and the decoder (in case of transcoding) this commit shares the AVOnce variable to prevent this. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

2010-01-13AAC: Compress codebook tables and optimise sign bit handlingMåns Rullgård
The codebooks each consist of small number of values repeated in groups of 2 or 4. Storing the codebooks as a packed list of 2- or 4-bit indexes into a table reduces their size substantially (from 7.5k to 1.5k), resulting in less cache pressure. For the band types with sign bits in the bitstream, storing the number and position of non-zero codebook values using a few bits avoids multiple get_bits() calls and floating-point comparisons which gcc handles miserably. Some float/int type punning also avoids gcc brain damage. Overall speedup 20-35% on Cortex-A8, 20% on Core i7. Originally committed as revision 21188 to svn://svn.ffmpeg.org/ffmpeg/trunk
