* lavc: shedule old encoding/decoding API for removalAnton Khirnov2021-01-26
| | | | | | | | It has been deprecated for 4 years and certain new codecs do not work with it. Also include AVCodecContext.refcounted_frames, as it has no effect with the new API.
* lavc/decode: move unrefcount_frame() right before its only callerAnton Khirnov2021-01-26
| | | | Will make wrapping it in deprecation guards simpler.

* avcodec/dolby_e: split decoder and parser more thoroughlyJames Almer2021-01-25
| | | | | | | | | Neither module should depend on the other. Move shared functions to its own file for this purpose, and ensure source files are compiled only when the required modules are enabled. Signed-off-by: James Almer <jamrial@gmail.com>
* avcodec/h263data, ituh263*: Make initializing RL inter table thread-safeAndreas Rheinhardt2021-01-25
| | | | | | | | | | | | 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.

* avcodec/ituh263dec: Don't initialize unused parts of RLTableAndreas Rheinhardt2021-01-25
| | | | | | | | | | The RLTable ff_rl_intra_aic is only used by ituh263dec and ituh263enc; the former only uses the RLTable's VLC, the latter only index_run, max_level and max_run. Yet ituh263dec also initializes the latter. This commit stops doing so. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/h261enc: Make encoder init-threadsafeAndreas Rheinhardt2021-01-25

* avcodec/h261dec: Don't initialize unused part of RLTableAndreas Rheinhardt2021-01-25
| | | | | | | | | | | The H.261 decoder only uses an RLTable's VLC table, yet it also initializes its index_run, max_level and max_run. This commit stops doing so; it will also simplify making this decoder init-threadsafe, as the H.261 decoder and encoder now initialize disjoint parts of their common RLTable.

* avcodec/mpegvideo_enc: Make mpv_encode_defaults thread-safeAndreas Rheinhardt2021-01-25
| | | | | | | | | This is a prerequisite for making any encoder that uses ff_mpv_encode_init() init-threadsafe; it already makes the AMV, the MJPEG and the MPEG-1/2 encoders init-threadsafe.

* avcodec/msmpeg4dec: Reuse identical MV VLCAndreas Rheinhardt2021-01-25
| | | | | | | | | | msmpeg4dec and ituh263dec both create VLCs with identical parameters out of ff_mvtab. Given that ff_msmpeg4_decode_init() always (indirectly) calls ff_h263_decode_init_vlc(), the VLC initialized by the latter can be directly used by msmpeg4dec. Doing so saves a bit more than 2KB from the .bss segment as well as the code to initialize a VLC. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/msmpeg4dec: Reuse identical RL VLCsAndreas Rheinhardt2021-01-25
| | | | | | | | | | | | | Some of the RLTables used by msmpeg4dec actually coincide with other RLTables: ff_rl_table[5] coincides with ff_h263_rl_inter (and ff_rl_table[2] with ff_mpeg4_rl_intra). Given that ff_h263_rl_inter is always initialized before msmpeg4dec's RLTables are initialized, one can just reuse the VLC tables by copying the pointers; after all, there are no ownership issues for static data. This saves 70912B from the .bss segment, translating into actual memory savings when this decoder is actually used. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/ituh263dec: Don't initialize unused RL VLCsAndreas Rheinhardt2021-01-25
| | | | | | | | | | The ff_rl_intra_aic RLTable is only used by ituh263dec and ituh263enc; the former is the only user of its RL VLC tables. It uses only the very first one of these VLC tables, but up until now all 32 are initialized, wasting 68696B from the .bss segment (or that amount of memory if this decoder has actually been used). This commit changes this. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/mpeg4videodec: Don't initialize unused RL VLCsAndreas Rheinhardt2021-01-25
| | | | | | | | | | The RLTables whose VLC tables are only used for intra blocks only use the very first VLC table; yet all 32 have been initialized. This commit stops this by switching to INIT_FIRST_VLC_RL. This saves 201624B from the .bss segment; in case the decoder is actually used, this translates into less memory used. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/msmpeg4dec: Don't initialize unused RL VLCsAndreas Rheinhardt2021-01-25
| | | | | | | | | For the RLTables ff_rl_table[0..2] only the very first VLC is only ever used, so it makes no sense to create 32 of them. This saves 285200B from the .bss segment; this amount of memory is actually saved when this decoder is used. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/h261dec: Don't initialize unused VLCsAndreas Rheinhardt2021-01-25
| | | | | | | | The H.261 decoder uses only the very first VLC of ff_h261_rl_tcoeff, so only initialize this one. Saves 68448B from the .bss segment; in case the decoder is actually used, this amount of memory is saved. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/rl: Allow to create only a few VLC tablesAndreas Rheinhardt2021-01-25

* avcodec/flashsv2enc: factorize updating block dimensionsMarton Balint2021-01-23
| | | | | | | | | | | | The patch changes the init function to initialize block dimensions to fixed 64x64 instead of the previously used image width/height based value. This should not cause any actual change in behaviour because block dimensions are recalculated on every keyframe in optimum_block_width() and optimum_block_height() functions and in the current code the result is always 64x64 regardless of the image dimensions used.

| | | | | | | | | | | | | tableprint.h does not declare anything as aligned; it just prints DECLARE_ALIGNED. So it can be removed; in fact, it needs to be removed, because mem_internal.h includes config.h which leads to warnings when building with hardcoded tables enabled because of redefinitions of CONFIG_HARDCODED_TABLES. (Furthermore, config.h is only valid for the target, not the host, so HAVE_LOCAL_ALIGNED might even be wrong here.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
