1320 Change the avfilter_add_colorspace() signature, make it accept an
1321 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
1323 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
1324 Add avfilter_add_colorspace().
1326 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
1327 Add av_match_ext(), it should be used in place of match_ext().

1349 Remove the next field from AVFilter, this is not anymore required.
1351 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1352 Introduce the avfilter_next() function.
1354 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1355 Change the signature of avfilter_register() to make it return an
1356 int. This is required since now the registration operation may fail.
1358 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1359 Make the pixdesc.h API public.
1361 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1365 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1366 Add a description field to AVFilter.
1368 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1369 Change the interface of avfilter_make_format_list() from

1373 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1374 Make avfilter_get_video_buffer() recursive and add the w and h
1377 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1378 Add w and h fields to AVFilterPic.
1380 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1381 This is now an unsigned int instead of a signed int.
1383 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1384 Add a pts field to AVSubtitle which gives the subtitle packet pts
1385 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1386 not work right without this.
1388 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1389 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1390 major version. Use AV_PKT_FLAG_KEY instead.
1392 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1393 av_lockmgr_register() can be used to register a callback function
1394 that lavc (and in the future, libraries that depend on lavc) can use
1395 to implement mutexes. The application should provide a callback function
1396 that implements the AV_LOCK_* operations described in avcodec.h.
1397 When the lock manager is registered, FFmpeg is guaranteed to behave
1398 correctly in a multi-threaded application.
1400 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1401 av_free_packet() is no longer an inline function. It is now exported.
1403 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1404 Please use NULL instead. This has been supported since r16506
1405 (lavf > 52.23.1, lavc > 52.10.0).
1407 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1408 The old decoding functions are deprecated, all new code should use the
1409 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1410 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1411 argument instead of a const uint8_t *buf / int buf_size pair.
1413 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1414 Introduce the av_fifo_space() function.
1416 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1417 Move AVPacket declaration from libavformat/avformat.h to
1418 libavcodec/avcodec.h.
1420 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1421 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1422 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1423 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1424 PIX_FMT_BGR32_1 are now macros.
1425 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1426 Re-sort the enum PixelFormat list accordingly.
1427 This change breaks API/ABI backward compatibility.
1429 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1430 Add the enum PixelFormat values:
1431 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1432 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1434 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1435 The Mersenne Twister PRNG implemented through the av_random* functions
1436 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1439 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1440 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1441 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1442 and av_fifo_realloc2.
1443 In addition, the order of the function arguments of av_fifo_generic_read
1444 was changed to match av_fifo_generic_write.
1445 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1446 applications, they may not use sizeof() or directly access members.
1448 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1449 Introduce a new metadata API (see av_metadata_get() and friends).
1450 The old API is now deprecated and should not be used anymore. This especially
1451 includes the following structure fields:
1452 - AVFormatContext.title
1453 - AVFormatContext.author
1454 - AVFormatContext.copyright
1455 - AVFormatContext.comment
1456 - AVFormatContext.album
1457 - AVFormatContext.year
1458 - AVFormatContext.track
1459 - AVFormatContext.genre
1462 - AVProgram.provider_name
