Raw Blame History 

  1. Never assume the API of libav* to be stable unless at least 1 month has passed

  2. since the last major version increase.

  3. 

  4. The last version increases were:

  5. libavcodec:  2012-01-27

  6. libavdevice: 2011-04-18

  7. libavfilter: 2011-04-18

  8. libavformat: 2012-01-27

  9. libswscale:  2011-06-20

  10. libavutil:   2011-04-18

  11. 

  12. 

  13. API changes, most recent first:

  31.   Add av_fast_padded_malloc() as alternative for av_realloc() when aligned

  32.   memory is required. The buffer will always have FF_INPUT_BUFFER_PADDING_SIZE

  33.   zero-padded bytes at the end.

  34. 

  35. 2012-01-31 - dd6d3b0 - lavf 54.01.0

  46.   f1caf01 Allow doing av_write_frame(ctx, NULL) for flushing possible

  47.           buffered data within a muxer. Added AVFMT_ALLOW_FLUSH for

  48.           muxers supporting it (av_write_frame makes sure it is called

  49.           only for muxers with this flag).

  50. 

  51. 2012-01-15 - lavc 53.34.0

  52.   New audio encoding API:

  53.   b2c75b6 Add CODEC_CAP_VARIABLE_FRAME_SIZE capability for use by audio

  54.           encoders.

  66.   e1d9dbf Add a new installed header - buffersrc.h

  67.   It contains a new function av_buffersrc_buffer() that allows passing

  68.   frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()

  69.   it allows for direct rendering.

  70.   1c9e340 Add avfilter_copy_frame_props() for copying properties from

  71.   AVFrame to AVFilterBufferRef.

  72. 

  73. 2011-12-25 - lavc 53.31.0

  88.   Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.

  89.   Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().

  90.   avcodec_decode_audio4() writes output samples to an AVFrame, which allows

  91.   audio decoders to use get_buffer().

  92. 

  93. 2011-12-04 - 560f773 - lavc 53.24.0

  94.   Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

  107.   Move some AVCodecContext fields to a new private struct, AVCodecInternal,

  108.   which is accessed from a new field, AVCodecContext.internal.

  109.   - fields moved:

  110.       AVCodecContext.internal_buffer       --> AVCodecInternal.buffer

  111.       AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count

  112.       AVCodecContext.is_copy               --> AVCodecInternal.is_copy

  123.           an interrupt callback and an options AVDictionary.

  124.           This will allow passing AVOptions to protocols after lavf

  125.           54.0.

  126. 

  127. 2011-11-06 - ba04ecf - lavu 51.14.0

  959.   new functions avcodec_decode_video2(), avcodec_decode_audio3() and

  960.   avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt

  961.   argument instead of a const uint8_t *buf / int buf_size pair.

  962.

  971.   Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,

  972.   PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.

  973.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  974.   PIX_FMT_BGR32_1 are now macros.

  975.   avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.

  976.   Re-sort the enum PixelFormat list accordingly.

  977.   This change breaks API/ABI backward compatibility.

  978. 

  979. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  980.   Add the enum PixelFormat values:

  981.   PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,

  982.   PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.

  983. 

  984. 2009-03-21 - r18116 - lavu 50.0.0  - av_random*

  985.   The Mersenne Twister PRNG implemented through the av_random* functions

  986.   was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions

  987.   instead.

  988. 

  989. 2009-03-08 - r17869 - lavu 50.0.0  - AVFifoBuffer

  990.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  991.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  992.   and av_fifo_realloc2.

  993.   In addition, the order of the function arguments of av_fifo_generic_read

  994.   was changed to match av_fifo_generic_write.

  995.   The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by

  996.   applications, they may not use sizeof() or directly access members.

  997. 

  998. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

  999.   Introduce a new metadata API (see av_metadata_get() and friends).

  1000.   The old API is now deprecated and should not be used anymore. This especially

  1001.   includes the following structure fields:

  1002.     - AVFormatContext.title

  1003.     - AVFormatContext.author

  1004.     - AVFormatContext.copyright

  1005.     - AVFormatContext.comment

  1006.     - AVFormatContext.album

  1007.     - AVFormatContext.year

  1008.     - AVFormatContext.track

  1009.     - AVFormatContext.genre

  1010.     - AVStream.language

  1011.     - AVStream.filename

  1012.     - AVProgram.provider_name

  1013.     - AVProgram.name

  1014.     - AVChapter.title
