301 'CodecID' identifier. Such code should either #undef CodecID or stop using the
302 CodecID name.
303
304 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

362 For audio formats with fixed frame size, the last frame
363 no longer needs to be padded with silence, libavcodec
364 will handle this internally (effectively all encoders

1326 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1327 Change the signature of avfilter_register() to make it return an

1331 Make the pixdesc.h API public.

1354
1355 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1356 Add a pts field to AVSubtitle which gives the subtitle packet pts
1357 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1358 not work right without this.
1359
1360 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1361 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1363
1364 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1365 av_lockmgr_register() can be used to register a callback function
1366 that lavc (and in the future, libraries that depend on lavc) can use
1367 to implement mutexes. The application should provide a callback function
1368 that implements the AV_LOCK_* operations described in avcodec.h.
1369 When the lock manager is registered, FFmpeg is guaranteed to behave
1370 correctly in a multi-threaded application.
1371
1372 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1373 av_free_packet() is no longer an inline function. It is now exported.
1374
1375 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1376 Please use NULL instead. This has been supported since r16506
1377 (lavf > 52.23.1, lavc > 52.10.0).
1378
1379 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1380 The old decoding functions are deprecated, all new code should use the
1381 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1382 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1383 argument instead of a const uint8_t *buf / int buf_size pair.
1384
1385 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1390 libavcodec/avcodec.h.
1391
1392 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1393 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1394 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1395 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1396 PIX_FMT_BGR32_1 are now macros.
1397 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1398 Re-sort the enum PixelFormat list accordingly.
1399 This change breaks API/ABI backward compatibility.
1400
1401 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1402 Add the enum PixelFormat values:
1403 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1404 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1405
1406 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1407 The Mersenne Twister PRNG implemented through the av_random* functions
1408 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1409 instead.
1410
1411 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1412 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1413 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1414 and av_fifo_realloc2.
1415 In addition, the order of the function arguments of av_fifo_generic_read
1416 was changed to match av_fifo_generic_write.
1417 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1418 applications, they may not use sizeof() or directly access members.
1419
1420 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1421 Introduce a new metadata API (see av_metadata_get() and friends).
1422 The old API is now deprecated and should not be used anymore. This especially
1423 includes the following structure fields:
1424 - AVFormatContext.title
1425 - AVFormatContext.author
1426 - AVFormatContext.copyright
1427 - AVFormatContext.comment
1428 - AVFormatContext.album
1429 - AVFormatContext.year
1430 - AVFormatContext.track
1431 - AVFormatContext.genre
1432 - AVStream.language
1433 - AVStream.filename
1434 - AVProgram.provider_name
1435 - AVProgram.name
1436 - AVChapter.title
