1367 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1368 Introduce the avfilter_next() function.
1370 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1371 Change the signature of avfilter_register() to make it return an
1372 int. This is required since now the registration operation may fail.
1374 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1375 Make the pixdesc.h API public.
1377 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1399 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1400 Add a pts field to AVSubtitle which gives the subtitle packet pts
1401 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1402 not work right without this.
1404 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1405 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1406 major version. Use AV_PKT_FLAG_KEY instead.
1408 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1409 av_lockmgr_register() can be used to register a callback function
1410 that lavc (and in the future, libraries that depend on lavc) can use
1411 to implement mutexes. The application should provide a callback function
1412 that implements the AV_LOCK_* operations described in avcodec.h.
1413 When the lock manager is registered, FFmpeg is guaranteed to behave
1414 correctly in a multi-threaded application.
1416 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1417 av_free_packet() is no longer an inline function. It is now exported.
1419 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1420 Please use NULL instead. This has been supported since r16506
1421 (lavf > 52.23.1, lavc > 52.10.0).
1423 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1424 The old decoding functions are deprecated, all new code should use the
1425 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1426 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1427 argument instead of a const uint8_t *buf / int buf_size pair.
1429 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1430 Introduce the av_fifo_space() function.
1432 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1433 Move AVPacket declaration from libavformat/avformat.h to
1434 libavcodec/avcodec.h.
1436 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1437 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1438 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1439 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1440 PIX_FMT_BGR32_1 are now macros.
1441 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1442 Re-sort the enum PixelFormat list accordingly.
1443 This change breaks API/ABI backward compatibility.
1445 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1446 Add the enum PixelFormat values:
1447 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1448 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1450 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1451 The Mersenne Twister PRNG implemented through the av_random* functions
1452 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1455 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1456 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1457 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1458 and av_fifo_realloc2.
1459 In addition, the order of the function arguments of av_fifo_generic_read
1460 was changed to match av_fifo_generic_write.
1461 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1462 applications, they may not use sizeof() or directly access members.
1464 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1465 Introduce a new metadata API (see av_metadata_get() and friends).
1466 The old API is now deprecated and should not be used anymore. This especially
1467 includes the following structure fields:
1468 - AVFormatContext.title
1469 - AVFormatContext.author
1470 - AVFormatContext.copyright
1471 - AVFormatContext.comment
1472 - AVFormatContext.album
1473 - AVFormatContext.year
1474 - AVFormatContext.track
1475 - AVFormatContext.genre
1478 - AVProgram.provider_name
