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

388 2011-12-25 - lavfi 2.14.0
389 e1d9dbf Add a new installed header - buffersrc.h
390 It contains a new function av_buffersrc_buffer() that allows passing
391 frames to the 'buffer' filter, but unlike av_vsrc_buffer_add_frame()
392 it allows for direct rendering.
393 1c9e340 Add avfilter_copy_frame_props() for copying properties from
394 AVFrame to AVFilterBufferRef.

411 Deprecate AVCODEC_MAX_AUDIO_FRAME_SIZE.
412 Deprecate avcodec_decode_audio3() in favor of avcodec_decode_audio4().
413 avcodec_decode_audio4() writes output samples to an AVFrame, which allows
414 audio decoders to use get_buffer().
416 2011-12-04 - 560f773 - lavc 53.24.0
417 Change AVFrame.data[4]/base[4]/linesize[4]/error[4] to [8] at next major bump.

430 Move some AVCodecContext fields to a new private struct, AVCodecInternal,
431 which is accessed from a new field, AVCodecContext.internal.
433 AVCodecContext.internal_buffer --> AVCodecInternal.buffer
434 AVCodecContext.internal_buffer_count --> AVCodecInternal.buffer_count
435 AVCodecContext.is_copy --> AVCodecInternal.is_copy

1287 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1288 The old decoding functions are deprecated, all new code should use the
1289 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1290 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1291 argument instead of a const uint8_t *buf / int buf_size pair.
1293 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1294 Introduce the av_fifo_space() function.
1296 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1297 Move AVPacket declaration from libavformat/avformat.h to
1298 libavcodec/avcodec.h.
1300 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1301 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1302 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1303 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1304 PIX_FMT_BGR32_1 are now macros.
1305 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1306 Re-sort the enum PixelFormat list accordingly.
1307 This change breaks API/ABI backward compatibility.
1309 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1310 Add the enum PixelFormat values:
1311 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1312 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1314 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1315 The Mersenne Twister PRNG implemented through the av_random* functions
1316 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1319 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1320 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1321 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1322 and av_fifo_realloc2.
1323 In addition, the order of the function arguments of av_fifo_generic_read
1324 was changed to match av_fifo_generic_write.
1325 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1326 applications, they may not use sizeof() or directly access members.
1328 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1329 Introduce a new metadata API (see av_metadata_get() and friends).
1330 The old API is now deprecated and should not be used anymore. This especially
1331 includes the following structure fields:
1332 - AVFormatContext.title
1333 - AVFormatContext.author
1334 - AVFormatContext.copyright
1335 - AVFormatContext.comment
1336 - AVFormatContext.album
1337 - AVFormatContext.year
1338 - AVFormatContext.track
1339 - AVFormatContext.genre
1342 - AVProgram.provider_name
