1286 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
1287 Introduce the avfilter_next() function.
1289 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1290 Change the signature of avfilter_register() to make it return an
1291 int. This is required since now the registration operation may fail.
1293 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1294 Make the pixdesc.h API public.
1296 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1297 Add a next field to AVFilter, this is used for simplifying the
1298 registration and management of the registered filters.
1300 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1301 Add a description field to AVFilter.
1303 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1304 Change the interface of avfilter_make_format_list() from
1305 avfilter_make_format_list(int n, ...) to
1306 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1308 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1309 Make avfilter_get_video_buffer() recursive and add the w and h
1312 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1313 Add w and h fields to AVFilterPic.
1315 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1316 This is now an unsigned int instead of a signed int.
1318 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1319 Add a pts field to AVSubtitle which gives the subtitle packet pts
1320 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1321 not work right without this.
1323 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1324 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1325 major version. Use AV_PKT_FLAG_KEY instead.
1327 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1328 av_lockmgr_register() can be used to register a callback function
1329 that lavc (and in the future, libraries that depend on lavc) can use
1330 to implement mutexes. The application should provide a callback function
1331 that implements the AV_LOCK_* operations described in avcodec.h.
1332 When the lock manager is registered, FFmpeg is guaranteed to behave
1333 correctly in a multi-threaded application.
1335 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1336 av_free_packet() is no longer an inline function. It is now exported.
1338 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1339 Please use NULL instead. This has been supported since r16506
1340 (lavf > 52.23.1, lavc > 52.10.0).
1342 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1343 The old decoding functions are deprecated, all new code should use the
1344 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1345 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1346 argument instead of a const uint8_t *buf / int buf_size pair.
1348 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1349 Introduce the av_fifo_space() function.
1351 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1352 Move AVPacket declaration from libavformat/avformat.h to
1353 libavcodec/avcodec.h.
1355 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1356 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1357 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1358 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1359 PIX_FMT_BGR32_1 are now macros.
1360 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1361 Re-sort the enum PixelFormat list accordingly.
1362 This change breaks API/ABI backward compatibility.
1364 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1365 Add the enum PixelFormat values:
1366 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1367 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1369 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1370 The Mersenne Twister PRNG implemented through the av_random* functions
1371 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1374 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1375 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1376 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1377 and av_fifo_realloc2.
1378 In addition, the order of the function arguments of av_fifo_generic_read
1379 was changed to match av_fifo_generic_write.
1380 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1381 applications, they may not use sizeof() or directly access members.
1383 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1384 Introduce a new metadata API (see av_metadata_get() and friends).
1385 The old API is now deprecated and should not be used anymore. This especially
1386 includes the following structure fields:
1387 - AVFormatContext.title
1388 - AVFormatContext.author
1389 - AVFormatContext.copyright
1390 - AVFormatContext.comment
1391 - AVFormatContext.album
1392 - AVFormatContext.year
1393 - AVFormatContext.track
1394 - AVFormatContext.genre
1397 - AVProgram.provider_name
