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: ?
|
|
libavformat: ?
|
|
libpostproc: ?
|
|
libswscale: ?
|
|
libavutil: 2009-03-08
|
|
|
|
|
|
API changes, most recent first:
|
|
|
|
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
