94a9ac1277
Guesses the sample aspect ratio of a frame, based on both the stream and the frame aspect ratio. Since the frame aspect ratio is set by the codec but the stream aspect ratio is set by the demuxer, these two may not be equal. This function tries to return the value that you should use if you would like to display the frame. Basic logic is to use the stream aspect ratio if it is set to something sane otherwise use the frame aspect ratio. This way a container setting, which is usually easy to modify can override the coded value in the frames.

Never assume the API of libav* to be stable unless at least 1 month has passed
|
|
since the last major version increase.
|
|
|
|
The last version increases were:
|
|
libavcodec: 2012-01-27
|
|
libavdevice: 2011-04-18
|
|
libavfilter: 2011-04-18
|
|
libavformat: 2012-01-27
|
|
libavresample: 2012-04-24
|
|
libpostproc: 2011-04-18
|
|
libswresample: 2011-09-19
|
|
libswscale: 2011-06-20
|
|
libavutil: 2011-04-18
|
|
|
|
|
|
API changes, most recent first:
|
|
|
|
2012-05-07 - xxxxxxx - lavf 54.5.100
|
|
Add av_guess_sample_aspect_ratio() function.

|
|
no longer needs to be padded with silence, libavcodec
|
|
will handle this internally (effectively all encoders
|

behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

|
|
2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY

|
2009-06-01 - f988ce6 - 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
|
|
that implements the AV_LOCK_* operations described in avcodec.h.
|
|
When the lock manager is registered, FFmpeg is guaranteed to behave
|
|
correctly in a multi-threaded application.
|
|
|
|
2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
|
|

|
|
|
|
2009-04-11 - 80d403f - 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 - 7a00bba - 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 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
|
|

|
|
|
|

|
|
libavcodec/avcodec.h.
|
|
|
|
2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
|
|
Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
|
|
PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
|
|
Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
|
|
PIX_FMT_BGR32_1 are now macros.
|
|
avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
|
|
Re-sort the enum PixelFormat list accordingly.
|
|
This change breaks API/ABI backward compatibility.
|
|
|
|
2009-03-22 - f82674e - 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 - ee6624e - 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 - 41dd680 - 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
|
|
was 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 - ec26457 - 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
|
