1130 'CodecID' identifier. Such code should either #undef CodecID or stop using the

1158 Add avfilter_pad_get_type() and avfilter_pad_get_name(). Those
1159 should now be used instead of accessing AVFilterPad members

1184 For audio formats with fixed frame size, the last frame
1185 no longer needs to be padded with silence, libavcodec
1186 will handle this internally (effectively all encoders
1187 behave as if they had CODEC_CAP_SMALL_LAST_FRAME set).

2301 Change the avfilter_add_colorspace() signature, make it accept an
2302 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
2304 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()

2307 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
2308 Add av_match_ext(), it should be used in place of match_ext().
2310 2010-01-01 - a1f547b - lavf 52.45.0 - av_guess_format()
2311 Add av_guess_format(), it should be used in place of guess_format().

2314 Add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and
2315 AV_METADATA_DONT_STRDUP_VAL.
2317 2009-12-13 - 277c733 - lavu 50.7.0 - avstring.h API

2329 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
2330 Remove the next field from AVFilter, this is not anymore required.
2332 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
2333 Introduce the avfilter_next() function.
2335 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
2336 Change the signature of avfilter_register() to make it return an
2337 int. This is required since now the registration operation may fail.
2339 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
2340 Make the pixdesc.h API public.
2342 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

2347 Add a description field to AVFilter.
2349 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
2350 Change the interface of avfilter_make_format_list() from

2354 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
2355 Make avfilter_get_video_buffer() recursive and add the w and h
2358 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
2359 Add w and h fields to AVFilterPic.
2361 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
2362 This is now an unsigned int instead of a signed int.
2364 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
2365 Add a pts field to AVSubtitle which gives the subtitle packet pts
2366 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
2367 not work right without this.
2369 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
2370 PKT_FLAG_KEY has been deprecated and will be dropped at the next
2371 major version. Use AV_PKT_FLAG_KEY instead.
2373 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
2374 av_lockmgr_register() can be used to register a callback function
2375 that lavc (and in the future, libraries that depend on lavc) can use
2376 to implement mutexes. The application should provide a callback function
2377 that implements the AV_LOCK_* operations described in avcodec.h.
2378 When the lock manager is registered, FFmpeg is guaranteed to behave
2379 correctly in a multi-threaded application.
2381 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
2382 av_free_packet() is no longer an inline function. It is now exported.
2384 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
2385 Please use NULL instead. This has been supported since r16506
2386 (lavf > 52.23.1, lavc > 52.10.0).
2388 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
2389 The old decoding functions are deprecated, all new code should use the
2390 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
2391 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
2392 argument instead of a const uint8_t *buf / int buf_size pair.
2394 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
2395 Introduce the av_fifo_space() function.
2397 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
2398 Move AVPacket declaration from libavformat/avformat.h to
2399 libavcodec/avcodec.h.
2401 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
2402 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
2403 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
2404 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
2405 PIX_FMT_BGR32_1 are now macros.
2406 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
2407 Re-sort the enum PixelFormat list accordingly.
2408 This change breaks API/ABI backward compatibility.
2410 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
2411 Add the enum PixelFormat values:
2412 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
2413 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
2415 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
2416 The Mersenne Twister PRNG implemented through the av_random* functions
2417 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
2420 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
2421 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
2422 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
2423 and av_fifo_realloc2.
2424 In addition, the order of the function arguments of av_fifo_generic_read
2425 was changed to match av_fifo_generic_write.
2426 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
2427 applications, they may not use sizeof() or directly access members.
2429 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
2430 Introduce a new metadata API (see av_metadata_get() and friends).
2431 The old API is now deprecated and should not be used anymore. This especially
2432 includes the following structure fields:
2433 - AVFormatContext.title
2434 - AVFormatContext.author
2435 - AVFormatContext.copyright
2436 - AVFormatContext.comment
2437 - AVFormatContext.album
2438 - AVFormatContext.year
2439 - AVFormatContext.track
2440 - AVFormatContext.genre
2443 - AVProgram.provider_name
