* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-311-0/+1
| | | | | | | | | | | There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/faxcompr: Avoid superfluous VLC structuresAndreas Rheinhardt2023-10-311-18/+14
| | | | | | | | Of all these VLCs here, only VLC.table was really used after init, so use the ff_vlc_init_tables API to get rid of them. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vlc: Use proper namespaceAndreas Rheinhardt2023-09-111-3/+3
| | | | | | | | | | | | | | | | 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 595324e143b57a52e2329eb47b84395c70f93087, 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>
* avcodec/vlc: Use structure instead of VLC_TYPE array as VLC elementAndreas Rheinhardt2022-06-171-2/+2
| | | | | | | | | | | | | | | | | | 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. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
