1317 Change the avfilter_add_colorspace() signature, make it accept an
1318 (AVFilterFormats **) rather than an (AVFilterFormats *) as before.
1320 2010-01-03 - 4fd1f18 - lavfi 1.13.0 - avfilter_add_colorspace()
1321 Add avfilter_add_colorspace().
1323 2010-01-02 - 8eb631f - lavf 52.46.0 - av_match_ext()
1324 Add av_match_ext(), it should be used in place of match_ext().
1326 2010-01-01 - a1f547b - lavf 52.45.0 - av_guess_format()
1327 Add av_guess_format(), it should be used in place of guess_format().

1330 Add av_metadata_set2(), AV_METADATA_DONT_STRDUP_KEY and
1331 AV_METADATA_DONT_STRDUP_VAL.
1333 2009-12-13 - 277c733 - lavu 50.7.0 - avstring.h API

1345 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
1346 Remove the next field from AVFilter, this is not anymore required.
1348 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1349 Introduce the avfilter_next() function.
1351 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1352 Change the signature of avfilter_register() to make it return an
1353 int. This is required since now the registration operation may fail.
1355 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1356 Make the pixdesc.h API public.
1358 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next

1363 Add a description field to AVFilter.
1365 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1366 Change the interface of avfilter_make_format_list() from

1370 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1371 Make avfilter_get_video_buffer() recursive and add the w and h
1374 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1375 Add w and h fields to AVFilterPic.
1377 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1378 This is now an unsigned int instead of a signed int.
1380 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1381 Add a pts field to AVSubtitle which gives the subtitle packet pts
1382 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1383 not work right without this.
1385 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1386 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1387 major version. Use AV_PKT_FLAG_KEY instead.
1389 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1390 av_lockmgr_register() can be used to register a callback function
1391 that lavc (and in the future, libraries that depend on lavc) can use
1392 to implement mutexes. The application should provide a callback function
1393 that implements the AV_LOCK_* operations described in avcodec.h.
1394 When the lock manager is registered, FFmpeg is guaranteed to behave
1395 correctly in a multi-threaded application.
1397 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1398 av_free_packet() is no longer an inline function. It is now exported.
1400 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1401 Please use NULL instead. This has been supported since r16506
1402 (lavf > 52.23.1, lavc > 52.10.0).
1404 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1405 The old decoding functions are deprecated, all new code should use the
1406 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1407 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1408 argument instead of a const uint8_t *buf / int buf_size pair.
1410 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1411 Introduce the av_fifo_space() function.
1413 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1414 Move AVPacket declaration from libavformat/avformat.h to
1415 libavcodec/avcodec.h.
1417 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1418 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1419 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1420 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1421 PIX_FMT_BGR32_1 are now macros.
1422 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1423 Re-sort the enum PixelFormat list accordingly.
1424 This change breaks API/ABI backward compatibility.
1426 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1427 Add the enum PixelFormat values:
1428 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1429 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1431 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1432 The Mersenne Twister PRNG implemented through the av_random* functions
1433 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1436 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1437 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1438 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1439 and av_fifo_realloc2.
1440 In addition, the order of the function arguments of av_fifo_generic_read
1441 was changed to match av_fifo_generic_write.
1442 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1443 applications, they may not use sizeof() or directly access members.
1445 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1446 Introduce a new metadata API (see av_metadata_get() and friends).
1447 The old API is now deprecated and should not be used anymore. This especially
1448 includes the following structure fields:
1449 - AVFormatContext.title
1450 - AVFormatContext.author
1451 - AVFormatContext.copyright
1452 - AVFormatContext.comment
1453 - AVFormatContext.album
1454 - AVFormatContext.year
1455 - AVFormatContext.track
1456 - AVFormatContext.genre
1459 - AVProgram.provider_name
