Never assume the API of libav* to be stable unless at least 1 week has passed since
the last major version increase.
The last version increases were:
libavcodec: ?
libavdevice: ?
libavfilter: 2009-10-18
libavformat: ?
libpostproc: ?
libswscale: ?
libavutil: 2009-03-08
API changes, most recent first:
2009-12-13 - r20826 - lavc 52.42.0 - AVStream
add avg_frame_rate
2009-12-12 - r20808 - lavu 50.6.0 - av_bmg_next()
Introduce the av_bmg_next() function.
2009-12-05 - r20734 - lavfi 1.12.0 - avfilter_draw_slice()
Add a slice_dir parameter to avfilter_draw_slice().
2009-11-26 - r20611 - lavfi 1.11.0 - AVFilter
Remove the next field from AVFilter, this is not anymore required.
2009-11-25 - r20607 - lavfi 1.10.0 - avfilter_next()
Introduce the avfilter_next() function.
2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
Change the signature of avfilter_register() to make it return an
int. This is required since now the registration operation may fail.
2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
Make the pixdesc.h API public.
2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next
Add a next field to AVFilter, this is used for simplifying the
registration and management of the registered filters.
2009-10-23 - r20356 - lavfi 1.4.1 - AVFilter.description
Add a description field to AVFilter.
2009-10-19 - r20302 - lavfi 1.3.0 - avfilter_make_format_list()
Change the interface of avfilter_make_format_list() from
avfilter_make_format_list(int n, ...) to
avfilter_make_format_list(enum PixelFormat *pix_fmts).
2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
Make avfilter_get_video_buffer() recursive and add the w and h
parameters to it.
2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
Added w and h fields to AVFilterPic.
2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
This is now an unsigned int instead of a signed int.
2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
Added a pts field to AVSubtitle which gives the subtitle's packet
PTS in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
not work right without this.
2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
PKT_FLAG_KEY has been deprecated and will be dropped for the next
major version. Use AV_PKT_FLAG_KEY instead.
2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
av_lockmgr_register() can be used to register a callback function
that lavc (and in the future, libraries that depend on lavc) can use
to implement mutexes. The application should provide a callback function
the implements the AV_LOCK_* operations described in avcodec.h.
When the lock manager is registered FFmpeg is guaranteed to behave
correct also in a multi-threaded application.
2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet
av_free_packet() is no longer an inline function. It is now exported.
2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree
Please use NULL instead. This has been supported since r16506
(lavf > 52.23.1, lavc > 52.10.0).
2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
The old decoding functions are deprecated, all new code should use the
new functions avcodec_decode_video2(), avcodec_decode_audio3() and
avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
argument instead of a const uint8_t *buf / int buf_size pair.
2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space
Introduce the av_fifo_space() function.
2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
Move AVPacket declaration from libavformat/avformat.h to
libavcodec/avcodec.h.
2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
Make the pixel formats: PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
PIX_FMT_BGRA, which were defined as macros, defined as enum
PixelFormat values, and viceversa make PIX_FMT_RGB32,
PIX_FMT_RGB32_1, PIX_FMT_BGR32, PIX_FMT_BGR32_1 defined as macros.
Also make avcodec_get_pix_fmt() recognize the "rgb32" and "bgr32"
aliases.
Re-sort the enum PixelFormat list accordingly.
This change breaks API/ABI backward compatibility.
2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
Add the enum PixelFormat values:
PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2009-03-21 - r18116 - lavu 50.0.0 - av_random*
The Mersenne Twister PRNG implemented through the av_random* functions
was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
instead.
2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
and av_fifo_realloc2.
In addition, the order of the function arguments of av_fifo_generic_read
were changed to match av_fifo_generic_write.
The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
applications, they may not use sizeof() or directly access members.
2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
Introduce a new metadata API (see av_metadata_get() and friends).
The old API is now deprecated and should not be used anymore. This especially
includes the following structure fields:
- AVFormatContext.title
- AVFormatContext.author
- AVFormatContext.copyright
- AVFormatContext.comment
- AVFormatContext.album
- AVFormatContext.year
- AVFormatContext.track
- AVFormatContext.genre
- AVStream.language
- AVStream.filename
- AVProgram.provider_name
- AVProgram.name
- AVChapter.title
