* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-31
| | | | | | | | | | | 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/error_resilience: Make applying decode_error_flags optionalAndreas Rheinhardt2023-09-15
| | | | | | | | | | Add a pointer parameter that if supplied will be used to return the updated decode_error_flags. This will allow to fix several races when using frame-threading; these resulted from AVFrame that the earlier code updated concurrently being used as source in an av_frame_ref() call in the decoder's update_thread_context.

* avcodec/vlc: Use proper namespaceAndreas Rheinhardt2023-09-11
| | | | | | | | | | | | | | | | 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/mpegvideo_dec: Don't use MotionEstContext as scratch spaceAndreas Rheinhardt2022-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Decoders that might use quarter pixel motion estimation (namely MPEG-4 as well as the VC-1 family) currently use MpegEncContext.me.qpel_(put|avg) as scratch space for pointers to arrays of function pointers. (MotionEstContext contains such pointers as it supports quarter pixel motion estimation.) The MotionEstContext is unused apart from this for the decoding part of mpegvideo. Using the context at all is for decoding is actually unnecessary and easily avoided: All codecs with quarter pixels set me.qpel_avg to qdsp.avg_qpel_pixels_tab, so one can just unconditionally use this in ff_mpv_reconstruct_mb(). MPEG-4 sets qpel_put to qdsp.put_qpel_pixels_tab or to qdsp.put_no_rnd_qpel_pixels_tab based upon whether the current frame is a b-frame with no_rounding or not, while the VC-1-based decoders set it to qdsp.put_qpel_pixels_tab unconditionally. Given that no_rounding is always zero for VC-1, using the same check for VC-1 as well as for MPEG-4 would work. Since ff_mpv_reconstruct_mb() already has exactly the right check (for hpeldsp), it can simply be reused. (This change will result in ff_mpv_motion() receiving a pointer to an array of NULL function pointers instead of a NULL pointer for codecs without qpeldsp (like MPEG-1/2). It doesn't matter.)

| | | | | | | | for videos with wmv9 rectangles, the region drawn by ff_mss12_decode_rect may be less than the entire video area. the wmv9 rectangles are used to calculate the ff_mss12_decode_rect draw region. Fixes tickets #3255 and #4043
* avcodec/codec_internal: Add macro to set AVCodec.long_nameAndreas Rheinhardt2022-09-03
| | | | | | | | It reduces typing: Before this patch, there were 105 codecs whose long_name-definition exceeded the 80 char line length limit. Now there are only nine of them. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | | | | and remove FF_CODEC_CAP_INIT_THREADSAFE All our native codecs are already init-threadsafe (only wrappers for external libraries and hwaccels are typically not marked as init-threadsafe yet), so it is only natural for this to also be the default state.

* avcodec/codec_internal: Use union for FFCodec decode/encode callbacksAndreas Rheinhardt2022-04-05
| | | | | | | | | | | 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.

* avcodec/codec_internal: Make FFCodec.decode use AVFrame*Andreas Rheinhardt2022-04-05

* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-21
| | | | | | | | | | | | | | | | 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.

* avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.hAndreas Rheinhardt2022-03-21
| | | | | | | | | | 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>
