1138 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1139 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1169 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1170 should now be used instead of accessing AVFilterPad members

1194 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1195 For audio formats with fixed frame size, the last frame
1196 no longer needs to be padded with silence, libavcodec
1197 will handle this internally (effectively all encoders
1198 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2312 Change the avfilter_add_colorspace() signature, make it accept an
2313 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
2315 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
2316 Add avfilter_add_colorspace().
2318 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
2319 Add av_match_ext(), it should be used in place of match_ext().

2341 Remove the next field from AVFilter, this is not anymore required.
2343 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2344 Introduce the avfilter_next() function.
2346 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2347 Change the signature of avfilter_register() to make it return an
2348 int. This is required since now the registration operation may fail.
2350 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2351 Make the pixdesc.h API public.
2353 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2358 Add a description field to AVFilter.
2360 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2361 Change the interface of avfilter_make_format_list() from

2365 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2366 Make avfilter_get_video_buffer() recursive and add the w and h
2369 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2370 Add w and h fields to AVFilterPic.
2372 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2373 This is now an unsigned int instead of a signed int.
2375 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2376 Add a pts field to AVSubtitle which gives the subtitle packet pts
2377 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2378 not work right without this.
2380 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2381 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2382 major version. Use AV_PKT_FLAG_KEY instead.
2384 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2385 av_lockmgr_register() can be used to register a callback function
2386 that lavc (and in the future, libraries that depend on lavc) can use
2387 to implement mutexes. The application should provide a callback function
2388 that implements the AV_LOCK_* operations described in avcodec.h.
2389 When the lock manager is registered, FFmpeg is guaranteed to behave
2390 correctly in a multi-threaded application.
2392 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2393 av_free_packet() is no longer an inline function. It is now exported.
2395 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2396 Please use NULL instead. This has been supported since r16506
2397 (lavf > 52.23.1, lavc > 52.10.0).
2399 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2400 The old decoding functions are deprecated, all new code should use the
2401 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2402 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2403 argument instead of a const uint8_t *buf / int buf_size pair.
2405 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2406 Introduce the av_fifo_space() function.
2408 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2409 Move AVPacket declaration from libavformat/avformat.h to
2410 libavcodec/avcodec.h.
2412 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2413 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2414 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2415 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2416 PIX_FMT_BGR32_1 are now macros.
2417 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2418 Re-sort the enum PixelFormat list accordingly.
2419 This change breaks API/ABI backward compatibility.
2421 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2422 Add the enum PixelFormat values:
2423 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2424 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2426 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2427 The Mersenne Twister PRNG implemented through the av_random* functions
2428 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2431 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2432 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2433 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2434 and av_fifo_realloc2.
2435 In addition, the order of the function arguments of av_fifo_generic_read
2436 was changed to match av_fifo_generic_write.
2437 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2438 applications, they may not use sizeof() or directly access members.
2440 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2441 Introduce a new metadata API (see av_metadata_get() and friends).
2442 The old API is now deprecated and should not be used anymore. This especially
2443 includes the following structure fields:
2444 - AVFormatContext.title
2445 - AVFormatContext.author
2446 - AVFormatContext.copyright
2447 - AVFormatContext.comment
2448 - AVFormatContext.album
2449 - AVFormatContext.year
2450 - AVFormatContext.track
2451 - AVFormatContext.genre
2454 - AVProgram.provider_name
