1150 Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
1151 To provide backwards compatibility, CodecID is now #defined as AVCodecID.

1206 2012-05-09 - 61930bd / a5117a2 - lavc 54.21.101 / 54.13.1
1207 For audio formats with fixed frame size, the last frame
1208 no longer needs to be padded with silence, libavcodec
1209 will handle this internally (effectively all encoders
1210 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2353 Remove the next field from AVFilter, this is not anymore required.
2355 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2356 Introduce the avfilter_next() function.
2358 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2359 Change the signature of avfilter_register() to make it return an
2360 int. This is required since now the registration operation may fail.
2362 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2363 Make the pixdesc.h API public.
2365 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2370 Add a description field to AVFilter.
2372 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2373 Change the interface of avfilter_make_format_list() from

2382 Add w and h fields to AVFilterPic.
2384 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size

2387 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2388 Add a pts field to AVSubtitle which gives the subtitle packet pts
2389 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2390 not work right without this.
2392 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2393 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2394 major version. Use AV_PKT_FLAG_KEY instead.
2396 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2397 av_lockmgr_register() can be used to register a callback function
2398 that lavc (and in the future, libraries that depend on lavc) can use
2399 to implement mutexes. The application should provide a callback function
2400 that implements the AV_LOCK_* operations described in avcodec.h.
2401 When the lock manager is registered, FFmpeg is guaranteed to behave
2402 correctly in a multi-threaded application.
2404 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2405 av_free_packet() is no longer an inline function. It is now exported.
2407 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2408 Please use NULL instead. This has been supported since r16506
2409 (lavf > 52.23.1, lavc > 52.10.0).
2411 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2412 The old decoding functions are deprecated, all new code should use the
2413 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2414 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2415 argument instead of a const uint8_t *buf / int buf_size pair.
2417 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2418 Introduce the av_fifo_space() function.
2420 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2421 Move AVPacket declaration from libavformat/avformat.h to
2422 libavcodec/avcodec.h.
2424 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2425 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2426 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2427 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2428 PIX_FMT_BGR32_1 are now macros.
2429 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2430 Re-sort the enum PixelFormat list accordingly.
2431 This change breaks API/ABI backward compatibility.
2433 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2434 Add the enum PixelFormat values:
2435 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2436 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2438 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2439 The Mersenne Twister PRNG implemented through the av_random* functions
2440 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2443 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2444 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2445 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2446 and av_fifo_realloc2.
2447 In addition, the order of the function arguments of av_fifo_generic_read
2448 was changed to match av_fifo_generic_write.
2449 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2450 applications, they may not use sizeof() or directly access members.
2452 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2453 Introduce a new metadata API (see av_metadata_get() and friends).
2454 The old API is now deprecated and should not be used anymore. This especially
2455 includes the following structure fields:
2456 - AVFormatContext.title
2457 - AVFormatContext.author
2458 - AVFormatContext.copyright
2459 - AVFormatContext.comment
2460 - AVFormatContext.album
2461 - AVFormatContext.year
2462 - AVFormatContext.track
2463 - AVFormatContext.genre
2466 - AVProgram.provider_name
