311 'CodecID' identifier. Such code should either #undef CodecID or stop using the
312 CodecID name.
313
314 2012-08-03 - 239fdf1 - lavu 51.37.1 - cpu.h

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

1336 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1337 Change the signature of avfilter_register() to make it return an

1341 Make the pixdesc.h API public.

1364
1365 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1366 Add a pts field to AVSubtitle which gives the subtitle packet pts
1367 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1368 not work right without this.
1369
1370 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1371 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1373
1374 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1375 av_lockmgr_register() can be used to register a callback function
1376 that lavc (and in the future, libraries that depend on lavc) can use
1377 to implement mutexes. The application should provide a callback function
1378 that implements the AV_LOCK_* operations described in avcodec.h.
1379 When the lock manager is registered, FFmpeg is guaranteed to behave
1380 correctly in a multi-threaded application.
1381
1382 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1383 av_free_packet() is no longer an inline function. It is now exported.
1384
1385 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1386 Please use NULL instead. This has been supported since r16506
1387 (lavf > 52.23.1, lavc > 52.10.0).
1388
1389 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1390 The old decoding functions are deprecated, all new code should use the
1391 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1392 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1393 argument instead of a const uint8_t *buf / int buf_size pair.
1394
1395 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1400 libavcodec/avcodec.h.
1401
1402 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1403 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1404 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1405 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1406 PIX_FMT_BGR32_1 are now macros.
1407 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1408 Re-sort the enum PixelFormat list accordingly.
1409 This change breaks API/ABI backward compatibility.
1410
1411 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1412 Add the enum PixelFormat values:
1413 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1414 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1415
1416 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1417 The Mersenne Twister PRNG implemented through the av_random* functions
1418 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1419 instead.
1420
1421 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1422 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1423 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1424 and av_fifo_realloc2.
1425 In addition, the order of the function arguments of av_fifo_generic_read
1426 was changed to match av_fifo_generic_write.
1427 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1428 applications, they may not use sizeof() or directly access members.
1429
1430 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1431 Introduce a new metadata API (see av_metadata_get() and friends).
1432 The old API is now deprecated and should not be used anymore. This especially
1433 includes the following structure fields:
1434 - AVFormatContext.title
1435 - AVFormatContext.author
1436 - AVFormatContext.copyright
1437 - AVFormatContext.comment
1438 - AVFormatContext.album
1439 - AVFormatContext.year
1440 - AVFormatContext.track
1441 - AVFormatContext.genre
1442 - AVStream.language
1443 - AVStream.filename
1444 - AVProgram.provider_name
1445 - AVProgram.name
1446 - AVChapter.title
