7 libavfilter: 2015-08-28
8 libavformat: 2015-08-28
9 libavresample: 2015-08-28

1136 Add avcodec_free_frame(). This function must now
1137 be used for freeing an AVFrame.
1139 2012-09-12 - e3e09f2 / 8919fee - lavu 51.73.100 / 51.41.0 - audioconvert.h
1140 Added AV_CH_LOW_FREQUENCY_2 channel mask value.

1163 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1164 To provide backwards compatibility, CodecID is now #defined as AVCodecID.
1165 Note that this can break user code that includes avcodec.h and uses the
1166 'CodecID' identifier. Such code should either #undef CodecID or stop using the

1194 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1195 should now be used instead of accessing AVFilterPad members
1198 2012-06-12 - 3630a07 / b0f0dfc - lavu 51.57.100 / 51.32.0 - audioconvert.h
1199 Add av_get_channel_layout_channel_index(), av_get_channel_name()
1200 and av_channel_layout_extract_channel().

1220 For audio formats with fixed frame size, the last frame
1221 no longer needs to be padded with silence, libavcodec
1222 will handle this internally (effectively all encoders
1223 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2366 Remove the next field from AVFilter, this is not anymore required.
2368 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2369 Introduce the avfilter_next() function.
2371 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2372 Change the signature of avfilter_register() to make it return an
2373 int. This is required since now the registration operation may fail.
2375 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2376 Make the pixdesc.h API public.
2378 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2383 Add a description field to AVFilter.
2385 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2386 Change the interface of avfilter_make_format_list() from

2397 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

2400 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2401 Add a pts field to AVSubtitle which gives the subtitle packet pts
2402 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2403 not work right without this.
2405 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2406 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2407 major version. Use AV_PKT_FLAG_KEY instead.
2409 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2410 av_lockmgr_register() can be used to register a callback function
2411 that lavc (and in the future, libraries that depend on lavc) can use
2412 to implement mutexes. The application should provide a callback function
2413 that implements the AV_LOCK_* operations described in avcodec.h.
2414 When the lock manager is registered, FFmpeg is guaranteed to behave
2415 correctly in a multi-threaded application.
2417 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2418 av_free_packet() is no longer an inline function. It is now exported.
2420 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2421 Please use NULL instead. This has been supported since r16506
2422 (lavf > 52.23.1, lavc > 52.10.0).
2424 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2425 The old decoding functions are deprecated, all new code should use the
2426 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2427 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2428 argument instead of a const uint8_t *buf / int buf_size pair.
2430 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2431 Introduce the av_fifo_space() function.
2433 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2434 Move AVPacket declaration from libavformat/avformat.h to
2435 libavcodec/avcodec.h.
2437 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2438 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2439 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2440 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2441 PIX_FMT_BGR32_1 are now macros.
2442 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2443 Re-sort the enum PixelFormat list accordingly.
2444 This change breaks API/ABI backward compatibility.
2446 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2447 Add the enum PixelFormat values:
2448 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2449 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2451 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2452 The Mersenne Twister PRNG implemented through the av_random* functions
2453 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2456 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2457 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2458 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2459 and av_fifo_realloc2.
2460 In addition, the order of the function arguments of av_fifo_generic_read
2461 was changed to match av_fifo_generic_write.
2462 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2463 applications, they may not use sizeof() or directly access members.
2465 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2466 Introduce a new metadata API (see av_metadata_get() and friends).
2467 The old API is now deprecated and should not be used anymore. This especially
2468 includes the following structure fields:
2469 - AVFormatContext.title
2470 - AVFormatContext.author
2471 - AVFormatContext.copyright
2472 - AVFormatContext.comment
2473 - AVFormatContext.album
2474 - AVFormatContext.year
2475 - AVFormatContext.track
2476 - AVFormatContext.genre
2479 - AVProgram.provider_name
