315 'CodecID' identifier. Such code should either #undef CodecID or stop using the
316 CodecID name.
317
318 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

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

1345 Make the pixdesc.h API public.

1368
1369 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1370 Add a pts field to AVSubtitle which gives the subtitle packet pts
1371 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1372 not work right without this.
1373
1374 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1375 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1377
1378 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1379 av_lockmgr_register() can be used to register a callback function
1380 that lavc (and in the future, libraries that depend on lavc) can use
1381 to implement mutexes. The application should provide a callback function
1382 that implements the AV_LOCK_* operations described in avcodec.h.
1383 When the lock manager is registered, FFmpeg is guaranteed to behave
1384 correctly in a multi-threaded application.
1385
1386 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1387 av_free_packet() is no longer an inline function. It is now exported.
1388
1389 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1390 Please use NULL instead. This has been supported since r16506
1391 (lavf > 52.23.1, lavc > 52.10.0).
1392
1393 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1394 The old decoding functions are deprecated, all new code should use the
1395 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1396 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1397 argument instead of a const uint8_t *buf / int buf_size pair.
1398
1399 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1404 libavcodec/avcodec.h.
1405
1406 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1407 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1408 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1409 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1410 PIX_FMT_BGR32_1 are now macros.
1411 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1412 Re-sort the enum PixelFormat list accordingly.
1413 This change breaks API/ABI backward compatibility.
1414
1415 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1416 Add the enum PixelFormat values:
1417 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1418 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1419
1420 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1421 The Mersenne Twister PRNG implemented through the av_random* functions
1422 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1423 instead.
1424
1425 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1426 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1427 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1428 and av_fifo_realloc2.
1429 In addition, the order of the function arguments of av_fifo_generic_read
1430 was changed to match av_fifo_generic_write.
1431 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1432 applications, they may not use sizeof() or directly access members.
1433
1434 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1435 Introduce a new metadata API (see av_metadata_get() and friends).
1436 The old API is now deprecated and should not be used anymore. This especially
1437 includes the following structure fields:
1438 - AVFormatContext.title
1439 - AVFormatContext.author
1440 - AVFormatContext.copyright
1441 - AVFormatContext.comment
1442 - AVFormatContext.album
1443 - AVFormatContext.year
1444 - AVFormatContext.track
1445 - AVFormatContext.genre
1446 - AVStream.language
1447 - AVStream.filename
1448 - AVProgram.provider_name
1449 - AVProgram.name
1450 - AVChapter.title
