Andreas Rheinhardt	5dc31bc67b	avcodec/aacps_common: Apply offset for VLCs during init This avoids having to apply it later after every get_vlc2(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
Andreas Rheinhardt	40a8cb9e6c	avcodec/aacps_common: Combine huffman tabels This allows to avoid the relocations inherent in an array to individual tables; it also reduces padding. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
Andreas Rheinhardt	774611a349	avcodec/aacps_common: Switch to ff_vlc_init_tables_from_lengths() It allows to replace codes of type uint16_t or uint32_t by symbols of type uint8_t. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
Andreas Rheinhardt	eb422c606a	avcodec/aacps_common: Avoid superfluous VLC structures For all VLCs here, the number of bits of the VLC is write-only, because it is hardcoded at the call site. Therefore one can replace these VLC structures with the only thing that is actually used: The pointer to the VLCElem table.

Andreas Rheinhardt	4fe91e3676	avcodec/aacps: Move initializing common stuff to aacdec_common.c ff_ps_init() initializes some tables for AAC parametric stereo and some of them are only valid for the fixed- or floating-point decoder, whereas others (namely VLCs) are valid for both. The latter are therefore initialized by ff_ps_init_common() and because the two versions of ff_ps_init() can be run concurrently, it is guarded by an AVOnce. Yet now that there is ff_aacdec_common_init_once() there is a better way to do this: Call ff_ps_init_common() from ff_aacdec_common_init_once(). That way there is no need to guard ff_ps_init_common() by an AVOnce any more. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
Andreas Rheinhardt	8c1e71a811	avcodec/aacps: Pass logctx as void* instead of AVCodecContext* Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
Andreas Rheinhardt	9cdf82c2c2	avcodec/vlc: Use proper namespace Therefore use a proper prefix for this API, e.g. ff_init_vlc_sparse -> ff_vlc_init_sparse ff_free_vlc -> ff_vlc_free INIT_VLC_LE -> VLC_INIT_LE INIT_VLC_USE_NEW_STATIC -> VLC_INIT_USE_STATIC (The ancient INIT_VLC_USE_STATIC has been removed in `595324e143`, so that the NEW has been dropped.) Finally, reorder the flags and change their values accordingly. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
Andreas Rheinhardt	2d764069be	avcodec/vlc: Use structure instead of VLC_TYPE array as VLC element In C, qualifiers for arrays are broken: const VLC_TYPE (foo)[2] is a pointer to an array of two const VLC_TYPE elements and unfortunately this is not compatible with a pointer to a const array of two VLC_TYPE, because the latter does not exist as array types are never qualified (the qualifier applies to the base type instead). This is the reason why get_vlc2() doesn't accept a const VLC table despite not modifying the table at all, as there is no automatic conversion from VLC_TYPE ()[2] to const VLC_TYPE (*)[2]. Fix this by using a structure VLCElem for the VLC table. This also has the advantage of making it clear which element is which.
