Andreas Rheinhardt	4243da4ff4	avcodec/codec_internal: Use union for FFCodec decode/encode callbacks This is possible, because every given FFCodec has to implement exactly one of these. Doing so decreases sizeof(FFCodec) and therefore decreases the size of the binary. Notice that in case of position-independent code the decrease is in .data.rel.ro, so that this translates to decreased memory consumption.

Andreas Rheinhardt	20f9727018	avcodec/codec_internal: Add FFCodec, hide internal part of AVCodec Up until now, codec.h contains both public and private parts of AVCodec. This exposes the internals of AVCodec to users and leads them into the temptation of actually using them and forces us to forward-declare structures and types that users can't use at all. This commit changes this by adding a new structure FFCodec to codec_internal.h that extends AVCodec, i.e. contains the public AVCodec as first member; the private fields of AVCodec are moved to this structure, leaving codec.h clean.

Andreas Rheinhardt	a688f3c13c	avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.h Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault. This reduces the amount of files that have to include internal.h (which comes with quite a lot of indirect inclusions), as e.g. most encoders don't need it. It is furthemore in preparation for moving the private part of AVCodec out of the public codec.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Martin Storsjö	a78f136f3f	configure: Use a separate config_components.h header for $ALL_COMPONENTS 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.

Andreas Rheinhardt	6739bb5a0e	avcodec/h263: Move functions only used once to their caller In this case it means moving ff_h263_pred_dc() resp. ff_h263_pred_acdc() to ituh263enc.c resp. ituh263dec.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	fea1f42e5f	avcodec/ituh263enc: Make static initializations thread-safe This already makes several encoders (namely FLV, H.263, H.263+ and RealVideo 1.0 and 2.0 and SVQ1) that use this init-threadsafe. It also makes the Snow encoder init-threadsafe; it was already marked as such since commit `d49210788b`, because it was thought to be harmless if one and the same object was initialized by multiple threads at the same time.

Andreas Rheinhardt	61fe481586	avcodec/h263data, ituh263*: Make initializing RL inter table thread-safe Up until now, ff_h263_rl_inter was initialized by both ituh263dec and ituh263enc; this is an obstacle in making the codecs that use this code init-threadsafe. This obstacle is eliminated by only initializing this RLTable from a single place that is guarded by a dedicated AVOnce.
