1288 Introduce the av_bmg_next() function.
1290 2009-12-05 - a13a543 - lavfi 1.12.0 - avfilter_draw_slice()
1291 Add a slice_dir parameter to avfilter_draw_slice().
1293 2009-11-26 - 4cc3f6a - lavfi 1.11.0 - AVFilter
1294 Remove the next field from AVFilter, this is not anymore required.
1296 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1297 Introduce the avfilter_next() function.
1299 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1300 Change the signature of avfilter_register() to make it return an
1301 int. This is required since now the registration operation may fail.
1303 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1304 Make the pixdesc.h API public.
1306 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1307 Add a next field to AVFilter, this is used for simplifying the
1308 registration and management of the registered filters.
1310 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1311 Add a description field to AVFilter.
1313 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1314 Change the interface of avfilter_make_format_list() from
1315 avfilter_make_format_list(int n, ...) to
1316 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1318 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1319 Make avfilter_get_video_buffer() recursive and add the w and h
1322 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1323 Add w and h fields to AVFilterPic.
1325 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1326 This is now an unsigned int instead of a signed int.
1328 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1329 Add a pts field to AVSubtitle which gives the subtitle packet pts
1330 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1331 not work right without this.
1333 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1334 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1335 major version. Use AV_PKT_FLAG_KEY instead.
1337 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1338 av_lockmgr_register() can be used to register a callback function
1339 that lavc (and in the future, libraries that depend on lavc) can use
1340 to implement mutexes. The application should provide a callback function
1341 that implements the AV_LOCK_* operations described in avcodec.h.
1342 When the lock manager is registered, FFmpeg is guaranteed to behave
1343 correctly in a multi-threaded application.
1345 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1346 av_free_packet() is no longer an inline function. It is now exported.
1348 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1349 Please use NULL instead. This has been supported since r16506
1350 (lavf > 52.23.1, lavc > 52.10.0).
1352 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1353 The old decoding functions are deprecated, all new code should use the
1354 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1355 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1356 argument instead of a const uint8_t *buf / int buf_size pair.
1358 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1359 Introduce the av_fifo_space() function.
1361 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1362 Move AVPacket declaration from libavformat/avformat.h to
1363 libavcodec/avcodec.h.
1365 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1366 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1367 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1368 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1369 PIX_FMT_BGR32_1 are now macros.
1370 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1371 Re-sort the enum PixelFormat list accordingly.
1372 This change breaks API/ABI backward compatibility.
1374 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1375 Add the enum PixelFormat values:
1376 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1377 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1379 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1380 The Mersenne Twister PRNG implemented through the av_random* functions
1381 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1384 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1385 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1386 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1387 and av_fifo_realloc2.
1388 In addition, the order of the function arguments of av_fifo_generic_read
1389 was changed to match av_fifo_generic_write.
1390 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1391 applications, they may not use sizeof() or directly access members.
1393 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1394 Introduce a new metadata API (see av_metadata_get() and friends).
1395 The old API is now deprecated and should not be used anymore. This especially
1396 includes the following structure fields:
1397 - AVFormatContext.title
1398 - AVFormatContext.author
1399 - AVFormatContext.copyright
1400 - AVFormatContext.comment
1401 - AVFormatContext.album
1402 - AVFormatContext.year
1403 - AVFormatContext.track
1404 - AVFormatContext.genre
1407 - AVProgram.provider_name
