* 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/vlc: Use proper namespaceAndreas Rheinhardt2023-09-111-6/+6
| | | | | | | | | | | | | | | | 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/internal: Move ff_set_dimensions() to decode.hAndreas Rheinhardt2022-08-271-1/+0
| | | | | | | | | Decoder-only, as the dimensions are set by the user when encoding. Also fixup the other headers a bit while removing unnecessary internal.h inclusions. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/internal: Move ff_get_buffer() to decode.hAndreas Rheinhardt2022-08-271-0/+1
| | | | | | | | | 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/vlc: Use structure instead of VLC_TYPE array as VLC elementAndreas Rheinhardt2022-06-171-1/+1
| | | | | | | | | | | | | | | | | | 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>
* avcodec/codec_internal: Make FFCodec.decode use AVFrame*Andreas Rheinhardt2022-04-051-4/+3
| | | | | | | | This increases type-safety by avoiding conversions from/through void*. It also avoids the boilerplate "AVFrame *frame = data;" line for non-subtitle decoders. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/ivi: Fix segfault on allocation errorAndreas Rheinhardt2020-09-151-1/+3
| | | | | | | | | | | If allocating the tiles array for indeo 4/5 fails, the context is in an inconsistent state, because the counter for the number of tiles is > 0. This will lead to a segfault when freeing the tiles' substructures. Fix this by setting the number of tiles to zero if the allocation was unsuccessful.
