* avcodec: add AVCodecContext.frame_num as 64 bit variant to frame_numberMarton Balint2023-02-131-3/+3
| | | | | | | | | | Frame counters can overflow relatively easily (INT_MAX number of frames is slightly more than 1 year for 60 fps content), so make sure we use 64 bit values for them. Also deprecate the old 32 bit frame_number attribute. Signed-off-by: Marton Balint <cus@passwd.hu>
* avcodec/codec_internal: Avoid deprecation warnings for channel_layoutsAndreas Rheinhardt2022-09-281-6/+2
| | | | | | | | | | | | | | | | | | AVCodec.channel_layouts is deprecated and Clang (unlike GCC) warns when setting this field in a codec definition. Fortunately, Clang (unlike GCC) allows to use FF_DISABLE_DEPRECATION_WARNINGS inside a definition (of an FFCodec), so that one can create simple macros to set AVCodec.channel_layouts that also suppress deprecation warnings for Clang. (Notice that some of the codec definitions were already inside FF_DISABLE/ENABLE_DEPRECATION_WARNINGS (that were not guarded by FF_API_OLD_CHANNEL_LAYOUT); these have been removed. Also notice that setting AVCodec.channel_layouts was not guarded by FF_API_OLD_CHANNEL_LAYOUT either, so testing disabling it it without removing all the codeblocks would not have worked.)

* avcodec/mlpenc: Remove dead channel layout checksAndreas Rheinhardt2022-09-221-6/+5
| | | | | | | | ff_encode_preinit() has already checked that the channel layout is equivalent to one of the layouts in AVCodec.ch_layouts. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mlpenc: Simplify channel layout comparisonsAndreas Rheinhardt2022-09-221-16/+14
| | | | | | | | | | | | | These encoders have AVCodec.ch_layouts set, so ff_encode_preinit() has already checked that the used channel layout is equivalent to one of these native layouts. Therefore one can simply compare the channel masks (with the added complication that one has to use av_channel_layout_subset() to get it, because the channel layout is not guaranteed to have AV_CHANNEL_ORDER_NATIVE).

* avcodec: Make ff_alloc_packet() based encoders accept user buffersAndreas Rheinhardt2022-08-271-2/+5
| | | | | | | | | | | | | | | | | | Up until now, these encoders received non-refcounted packets (whose data was owned by the corresponding AVCodecContext) from ff_alloc_packet(); these packets were made refcounted lateron by av_packet_make_refcounted() generically. This commit makes these encoders accept user-supplied buffers by replacing av_packet_make_refcounted() with an equivalent function that is based upon get_encode_buffer(). (I am pretty certain that one can also set the flag for mpegvideo- based encoders, but I want to double-check this later. What is certain is that it reallocates the buffer owned by the AVCodecContext which should maybe be moved to encode.c, so that proresenc_kostya.c and ttaenc.c can make use of it, too.)

* avcodec/codec_internal: Use union for FFCodec decode/encode callbacksAndreas Rheinhardt2022-04-051-2/+2
| | | | | | | | | | | 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: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-211-20/+20
| | | | | | | | | | | | | | | | 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 Rheinhardt2022-03-211-1/+1
| | | | | | | | | | 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>

| | | | | | | | | | TrueHD/MLP is one of the audio formats with keyframes.

* avcodec/encode: Always use intermediate buffer in ff_alloc_packet2()Andreas Rheinhardt2021-06-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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/mlpenc: Add const where appropriateAndreas Rheinhardt2021-05-021-10/+12
| | | | | | | | | | | | The MLP/TrueHD encoder uses pointers to non-const to access several static objects that are only initialized at runtime and are therefore not declared as const. This does not result in compiler warnings, but it is fragile, as these objects are really not to be modified as they are not owned by any encoder instance. Therefore this commit adds const to the pointed to type of the pointers used to access them after their initialization. One object has even been made const.
