* avcodec/mpegpicture: Move encoding_error and mb_var_sum to MpegEncCtxAndreas Rheinhardt2022-08-10
| | | | | | | | These fields are only ever set by the encoder for the current picture and for no other picture. So only one set of these values needs to exist, so move them to MpegEncContext. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/snowenc: Don't pass int[2] as parameter declared as int[3]Andreas Rheinhardt2022-07-23
| | | | | | | | | | | | | | | | | | | | check_block_inter() currently does this when calling check_block(). This leads to a -Wstringop-overflow= warning when compiling with GCC 12.1. Given that the main part of the body of check_block() consists of an "if (intra) { ... } else { ... }" which is true iff check_block() is not called from check_block_inter(), it makes sense to fix this by just inlining check_block() check_block_inter() and turning check_block() into a new check_block_intra() (with the inter parts removed, of course). This should also not make much of a difference for the generated code given that both check_block() as well as check_block_inter() are already marked as av_always_inline, so this commit follows this route to fix the issue.

* avcodec: Make init-threadsafety the defaultAndreas Rheinhardt2022-07-18
| | | | | | | | | | | 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/mpegvideo: Make new_picture an ordinary AVFrameAndreas Rheinhardt2022-04-01
| | | | | | | | | It is currently a "Picture", an mpegvideo-specific type that has a lot of baggage, all of which is unnecessary for new_picture, because only its embedded AVFrame is ever used. So just use an ordinary AVFrame. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* 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>

* avcodec/mpegpicture: Decrease size of encoding_error arrayAndreas Rheinhardt2022-01-13
| | | | | | | | | | | | | The current size is AV_NUM_DATA_POINTERS (i.e. eight). This number is chosen in order to minimize the amount of allocations for AVFrame.extended_(data|buf) for audio; it is meaningless for video for which four is sufficient. So decrease this array in order to minimize what is copied in ff_mpeg_ref_picture() and at the places that copy a whole MpegEncContext. Also do the same for snowenc.

* avcodec/encode: Always use intermediate buffer in ff_alloc_packet2()Andreas Rheinhardt2021-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, ff_alloc_packet2() has a min_size parameter: It is supposed to be a lower bound on the final size of the packet to allocate. If it is not too far from the upper bound (namely, if it is at least half the upper bound), then ff_alloc_packet2() already allocates the final, already refcounted packet; if it is not, then the packet is not refcounted and its data only points to a buffer owned by the AVCodecContext (in this case, the packet will be made refcounted in encode_simple_internal() in libavcodec/encode.c). The goal of this was to avoid data copies and intermediate buffers if one has a precise lower bound. Yet those encoders for which precise lower bounds exist have recently been switched to ff_get_encode_buffer() (which automatically allocates final buffers), leaving only two encoders to actually set the min_size to something else than zero (namely aliaspixenc and hapenc). Both of these encoders use a very low lower bound that is not helpful in any nontrivial case. This commit therefore removes the min_size parameter as well as the codepath in ff_alloc_packet2() for the allocation of final buffers. Furthermore, the function has been renamed to ff_alloc_packet() and moved to encode.h alongside ff_get_encode_buffer(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

* lavc/snowenc: Expose an option to set the rc_eq expressionAlexander Strasser2020-08-12
| | | | | | | | | | | | | | | Snow uses the ratecontrol module, but does not expose a way to set the rc_eq expression. The default expression, set in the ratecontrol module, will always be used. Make it possible to set rc_eq by adding an AVOption to snowenc. The option definition is mostly a copy from the mpegvideo common options definition of rc_eq (libavcodec/mpegvideo.h), with some minor style adjustments to be closer to the other snowenc option initializer expressions.
