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. libpostproc: 2011-04-18 (deprecated, to be removed later)

  10. libswscale:  2011-06-20

  11. libavutil:   2011-04-18

  12. 

  13. 

  14. API changes, most recent first:

  15. 

  16. 2012-01-30 - xxxxxxx - lavu 51.22.0 - intfloat.h

  17.   Add a new installed header libavutil/intfloat.h with int/float punning

  18.   functions.

  19. 

  20. 2012-01-25 - lavf 53.22.0

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

  22.           buffered data within a muxer. Added AVFMT_ALLOW_FLUSH for

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

  24.           only for muxers with this flag).

  25. 

  26. 2012-01-15 - lavc 53.34.0

  27.   New audio encoding API:

  28.   b2c75b6 Add CODEC_CAP_VARIABLE_FRAME_SIZE capability for use by audio

  29.           encoders.

  30.   5ee5fa0 Add avcodec_fill_audio_frame() as a convenience function.

  31.   b2c75b6 Add avcodec_encode_audio2() and deprecate avcodec_encode_audio().

  32.           Add AVCodec.encode2().

  33. 

  34. 2012-01-12 - 3167dc9 - lavfi 2.15.0

  35.   Add a new installed header -- libavfilter/version.h -- with version macros.

  36. 

  37. 2011-01-03 - b73ec05 - lavu 51.21.0

  38.   Add av_popcount64

  39. 

  40. 2011-12-25 - lavfi 2.14.0

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

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

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

  44.   it allows for direct rendering.

  45.   1c9e340 Add avfilter_copy_frame_props() for copying properties from

  46.   AVFrame to AVFilterBufferRef.

  47. 

  48. 2011-12-25 - lavc 53.31.0

  49.   Add the following new fields to AVFrame:

  50.     b58dbb5 sample_aspect_ratio

  51.     3a2ddf7 width, height

  52.     8a4a5f6 format

  53. 

  54. 2011-12-18 - 8400b12 - lavc 53.28.1

  55.   Deprecate AVFrame.age. The field is unused.

  56. 

  57. 2011-12-12 - 5266045 - lavf 53.17.0

  58.   Add avformat_close_input().

  60. 

  61. 2011-12-02 - 0eea212 - lavc 53.25.0

  62.   Add nb_samples and extended_data fields to AVFrame.

  63.   Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.

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

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

  66.   audio decoders to use get_buffer().

  67. 

  68. 2011-12-04 - 560f773 - lavc 53.24.0

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

  70.   Change AVPicture.data[4]/linesize[4] to [8] at next major bump.

  71.   Change AVCodecContext.error[4] to [8] at next major bump.

  72.   Add AV_NUM_DATA_POINTERS to simplify the bump transition.

  73. 

  74. 2011-11-23 - bbb46f3 - lavu 51.18.0

  75.   Add av_samples_get_buffer_size(), av_samples_fill_arrays(), and

  76.   av_samples_alloc(), to samplefmt.h.

  79.   Add planar sample formats and av_sample_fmt_is_planar() to samplefmt.h.

  80. 

  81. 2011-11-19 - f3a29b7 - lavc 53.21.0

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

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

  84.   - fields moved:

  85.       AVCodecContext.internal_buffer       --> AVCodecInternal.buffer

  86.       AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count

  87.       AVCodecContext.is_copy               --> AVCodecInternal.is_copy

  88. 

  89. 2011-11-16 - 6270671 - lavu 51.16.0

  90.   Add av_timegm()

  91. 

  92. 2011-11-13 - lavf 53.15.0

  94.   interrupt callbacks.

  96.           AVFormatContext.

  97.   1dee0ac Add avio_open2() with additional parameters. Those are

  98.           an interrupt callback and an options AVDictionary.

  99.           This will allow passing AVOptions to protocols after lavf

  100.           54.0.

  101. 

  102. 2011-11-06 - ba04ecf - lavu 51.14.0

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

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

  948.   Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and

  949.   PIX_FMT_BGR32_1 are now macros.

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

  951.   Re-sort the enum PixelFormat list accordingly.

  952.   This change breaks API/ABI backward compatibility.

  953.

  955.   Add the enum PixelFormat values:

  965.   av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped

  966.   and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write

  967.   and av_fifo_realloc2.

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

  969.   was changed to match av_fifo_generic_write.

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

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

  972. 

  973. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API

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