2 since the last major version increase.

182 To provide backwards compatibility, PixelFormat is now #defined as

289 For audio formats with fixed frame size, the last frame

390 0.8 branch was cut here
391 ----------------------------->8--------------------------------------
393 2012-01-15 - lavc 53.34.0

397 5ee5fa0 Add avcodec_fill_audio_frame() as a convenience function.
398 b2c75b6 Add avcodec_encode_audio2() and deprecate avcodec_encode_audio().
399 Add AVCodec.encode2().
401 2012-01-12 - 3167dc9 - lavfi 2.15.0
402 Add a new installed header -- libavfilter/version.h -- with version macros.
404 2011-01-03 - b73ec05 - lavu 51.21.0
407 2011-12-25 - lavfi 2.14.0
408 e1d9dbf Add a new installed header - buffersrc.h
409 It contains a new function av_buffersrc_buffer() that allows passing
410 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
411 it allows for direct rendering.
412 1c9e340 Add avfilter_copy_frame_props() for copying properties from
413 AVFrame to AVFilterBufferRef.

430 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
431 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
432 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
433 audio decoders to use get_buffer().
435 2011-12-04 - 560f773 - lavc 53.24.0
436 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.
437 Change AVPicture.data[4]/linesize[4] to [8] at next major bump.
438 Change AVCodecContext.error[4] to [8] at next major bump.

1285 not work right without this.
1287 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1288 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1289 major version. Use AV_PKT_FLAG_KEY instead.
1291 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1292 av_lockmgr_register() can be used to register a callback function
1293 that lavc (and in the future, libraries that depend on lavc) can use
1294 to implement mutexes. The application should provide a callback function
1295 that implements the AV_LOCK_* operations described in avcodec.h.
1296 When the lock manager is registered, FFmpeg is guaranteed to behave
1297 correctly in a multi-threaded application.
1299 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1300 av_free_packet() is no longer an inline function. It is now exported.
1302 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1303 Please use NULL instead. This has been supported since r16506
1304 (lavf > 52.23.1, lavc > 52.10.0).
1306 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1307 The old decoding functions are deprecated, all new code should use the
1308 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1309 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1310 argument instead of a const uint8_t *buf / int buf_size pair.
1312 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1313 Introduce the av_fifo_space() function.
1315 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1316 Move AVPacket declaration from libavformat/avformat.h to
1317 libavcodec/avcodec.h.
1319 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1320 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1321 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1322 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1323 PIX_FMT_BGR32_1 are now macros.
1324 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1325 Re-sort the enum PixelFormat list accordingly.
1326 This change breaks API/ABI backward compatibility.
1328 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1329 Add the enum PixelFormat values:
1330 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1331 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1333 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1334 The Mersenne Twister PRNG implemented through the av_random* functions
1335 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1338 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1339 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1340 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1341 and av_fifo_realloc2.
1342 In addition, the order of the function arguments of av_fifo_generic_read
1343 was changed to match av_fifo_generic_write.
1344 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1345 applications, they may not use sizeof() or directly access members.
1347 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1348 Introduce a new metadata API (see av_metadata_get() and friends).
1349 The old API is now deprecated and should not be used anymore. This especially
1350 includes the following structure fields:
1351 - AVFormatContext.title
1352 - AVFormatContext.author
1353 - AVFormatContext.copyright
1354 - AVFormatContext.comment
1355 - AVFormatContext.album
1356 - AVFormatContext.year
1357 - AVFormatContext.track
1358 - AVFormatContext.genre
1361 - AVProgram.provider_name
