* avcodec/ac3: Move non-(de|en)coder-only parts out of ac3.hAndreas Rheinhardt2022-05-15
| | | | | | | | | | Move AC3HeaderInfo into ac3_parser_internal.h and the rest into a new header ac3defs.h. This also breaks an include cycle of ac3.h and ac3tab.h (the latter now only needs ac3defs.h). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/ac3tab: Move some tables only used by ac3.c to itAndreas Rheinhardt2022-05-15

* Remove unnecessary libavutil/(avutil|common|internal).h inclusionsAndreas Rheinhardt2022-02-24
| | | | | | | | | | Some of these were made possible by moving several common macros to libavutil/macros.h. While just at it, also improve the other headers a bit. Reviewed-by: Martin Storsjö <martin@martin.st> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* Remove/replace some unnecessary avcodec.h inclusionsAndreas Rheinhardt2021-07-22
| | | | | | | Also remove other unnecessary headers and include headers directly while at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* | avcodec/ac3: always use hardcoded tablesGanesh Ajjanagadde2015-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The table in question is a 253 byte one. In fact, it turns out that dynamic generation of the table results in an increased binary size. Code compiled with GCC 5.2.0, x86-64 (size in bytes), before and after patch: old: 62321064 libavcodec/libavcodec.so.57 new: 62320536 libavcodec/libavcodec.so.57 Thus, it always make sense to statically allocate this. Tested with FATE with/without --enable-hardcoded-tables. Reviewed-by: wm4 <nfxjfg@googlemail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
* | ac3: validate end in ff_ac3_bit_alloc_calc_maskAndreas Cadhalpun2015-04-16
| | | | | | | | | | | | | | | | | | | | | | This fixes an invalid read if end is 0: band_end = ff_ac3_bin_to_band_tab[end-1] + 1; Depending on what is before the array, this can cause stack smashing, when band_end becomes too large.
