Nicolas George	926481078b	lavu/opt: fix av_opt_get_key_value() API. Do not skip the end delimiter. Reserve positive return values. This is an API break, but the function was introduced less than two weeks ago.	12 years ago

Janne Grunau	bf5f46b4cc	APIChanges: add entry for av_read_packet deprecation	12 years ago
Stefano Sabatini	7945665200	lavfi: store and propagate number of channels information in audio buffer properties The channels field is required since the channel layout is not always available.	12 years ago

Nicolas George	3bdf4971ba	lavu/opt: implement av_opt_get_key_value(). This function does the low-level work of av_opt_set_from_string() but can be used when there is no option context or when a generic handling of unknown keys is needed. av_opt_set_from_string() is changed to make use of it.	12 years ago

Michael Niedermayer	ac090fa68c	lavu: keep context size variables They are essential to be able to use the utils without av_malloc() That is for example use with malloc(), memalign(), some other private allocation function, on the stack or others. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	add3a6902e	lavu: bump major to 52 In addition to the recent tables mess, the AVOption defaults behavior changed, so an old lavc used with a new lavu will get completely messed up defaults.	12 years ago
Anton Khirnov	9cac8a5199	APIchanges: update lavr bump date	12 years ago
Nathan Caldwell	a893655bda	avutil: Add AVERROR_EXPERIMENTAL Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Clément Bœsch	6fb2fd895e	lavc: add lavfi metadata support. This commit introduces a new AVPacket side data type: AV_PKT_DATA_STRINGS_METADATA. Its main goal is to provide a way to transmit the metadata from the AVFilterBufferRef up to the AVFrame. This is at the moment "only" useful for lavfi input from libavdevice: lavd/lavfi only outputs packets, and the metadata from the buffer ref kept in its context needs to be transmitted from the packet to the frame by the decoders. The buffer ref can be destroyed at any time (along with the metadata), and a duplication of the AVPacket needs to duplicate the metadata as well, so the choice of using the side data to store them was selected. Making sure lavd/lavfi raises the metadata is useful to allow tools like ffprobe to access the filters metadata (it is at the moment the only way); ffprobe will now automatically show the AVFrame metadata in any customizable output format for users. API users will also be able to access the AVFrame->metadata pointer the same way ffprobe does (av_frame_get_metadata). All the changes are done in this single commit to avoid some memory leaks: for instances, the changes in lavfi/avcodec.c are meant to duplicate the metadata from the buffer ref into the AVFrame. Unless we have an internal way of freeing the AVFrame->metadata automatically, it will leak in most of the user apps. To fix this problem, we introduce AVCodecContext->metadata and link avctx->metadata to the current frame->metadata and free it at each decode frame call (and in the codec closing callback for the last one). But doing this also means to update the way the tiff decoder already handles the AVFrame->metadata (it's the only one decoder with frame metadata at the moment), by making sure it is not trying to free a pointer already freed by the lavc internals. The lavfi/avcodec.c buffer ref code is based on an old Thomas Kühnel work, the rest of the code belongs to the commit author.

Anton Khirnov	d2fcb356ca	pixdesc: add functions for accessing pixel format descriptors. Make av_pix_fmt_descriptors table static on next major bump. Making the table public is dangerous, since the caller has no way to know how large it actually is. It also prevents adding new fields to AVPixFmtDescriptor without a major bump.	12 years ago
Martin Storsjö	9a92aea27b	avutil: Add functions for allocating opaque contexts for algorithms The current API where the plain size is exposed is not of much use - in most cases it is allocated dynamically anyway. If allocated e.g. on the stack via an uint8_t array, there's no guarantee that the struct's members are aligned properly (unless the array is overallocated and the opaque pointer within it manually aligned to some unspecified alignment).

Clément Bœsch	0065d31dcd	APIchanges: fill hashes. Also fix some dates (use the commit date instead of the author date).	12 years ago
Clément Bœsch	a04cb9823b	Move subrip/text API change info from Changelog to doc/APIchanges. Note that a lavf bump was missing so I'm using 54.28.100 as a reference.	12 years ago
jamal	a70b4935f1	Add missing version macros to libraries Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	a42aadabc6	lavc: add avcodec_free_frame(). Since an AVFrame now has malloced members (extended_data), it must have a destructor.	12 years ago
Tim Walker	8919fee7d2	lavu/audioconvert: add a second low frequency channel. Can be used by DTS-HD, TrueHD and E-AC-3, among others. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago
Stefano Sabatini	29e972f67c	lavu/parseutils: add av_small_strptime() Make internal small_strptime() function public, and use it in place of strptime(). This allows to avoid a dependency on strptime() on systems which do not support it. In particular, fix trac ticket #992.	12 years ago
Martin Storsjö	686a329395	avopt: Reorder the default_val struct, making i64 the first field Also mention this change in APIchanges. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Anton Khirnov	2ff67c909c	lavc: fix mixing CODEC_ID/AV_CODEC_ID in C++ code. C++ does not allow to mix different enums, so e.g. code comparing ACodecID with CodecID would fail to compile with gcc. This very evil hack should fix this problem.	13 years ago
Mans Rullgard	987170cb9d	dict: add av_dict_count() This adds a function to retrieve the number of entries in a dictionary and updates the places directly accessing what should be an opaque struct to use this new function instead. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
