1306 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
1307 Make the pixdesc.h API public.
1309 2009-10-27 - 243110f - lavfi 1.5.0 - AVFilter.next
1310 Add a next field to AVFilter, this is used for simplifying the
1311 registration and management of the registered filters.
1313 2009-10-23 - cccd292 - lavfi 1.4.1 - AVFilter.description
1314 Add a description field to AVFilter.
1316 2009-10-19 - 6b5dc05 - lavfi 1.3.0 - avfilter_make_format_list()
1317 Change the interface of avfilter_make_format_list() from
1318 avfilter_make_format_list(int n, ...) to
1319 avfilter_make_format_list(enum PixelFormat *pix_fmts).
1321 2009-10-18 - 0eb4ff9 - lavfi 1.0.0 - avfilter_get_video_buffer()
1322 Make avfilter_get_video_buffer() recursive and add the w and h
1325 2009-10-07 - 46c40e4 - lavfi 0.5.1 - AVFilterPic
1326 Add w and h fields to AVFilterPic.
1328 2009-06-22 - 92400be - lavf 52.34.1 - AVFormatContext.packet_size
1329 This is now an unsigned int instead of a signed int.
1331 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1332 Add a pts field to AVSubtitle which gives the subtitle packet pts
1333 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1334 not work right without this.
1336 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1337 PKT_FLAG_KEY has been deprecated and will be dropped at the next
1338 major version. Use AV_PKT_FLAG_KEY instead.
1340 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1341 av_lockmgr_register() can be used to register a callback function
1342 that lavc (and in the future, libraries that depend on lavc) can use
1343 to implement mutexes. The application should provide a callback function
1344 that implements the AV_LOCK_* operations described in avcodec.h.
1345 When the lock manager is registered, FFmpeg is guaranteed to behave
1346 correctly in a multi-threaded application.
1348 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1349 av_free_packet() is no longer an inline function. It is now exported.
1351 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1352 Please use NULL instead. This has been supported since r16506
1353 (lavf > 52.23.1, lavc > 52.10.0).
1355 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1356 The old decoding functions are deprecated, all new code should use the
1357 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1358 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1359 argument instead of a const uint8_t *buf / int buf_size pair.
1361 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
1362 Introduce the av_fifo_space() function.
1364 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
1365 Move AVPacket declaration from libavformat/avformat.h to
1366 libavcodec/avcodec.h.
1368 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1369 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1370 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1371 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1372 PIX_FMT_BGR32_1 are now macros.
1373 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1374 Re-sort the enum PixelFormat list accordingly.
1375 This change breaks API/ABI backward compatibility.
1377 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1378 Add the enum PixelFormat values:
1379 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1380 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1382 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1383 The Mersenne Twister PRNG implemented through the av_random* functions
1384 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1387 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1388 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1389 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1390 and av_fifo_realloc2.
1391 In addition, the order of the function arguments of av_fifo_generic_read
1392 was changed to match av_fifo_generic_write.
1393 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1394 applications, they may not use sizeof() or directly access members.
1396 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1397 Introduce a new metadata API (see av_metadata_get() and friends).
1398 The old API is now deprecated and should not be used anymore. This especially
1399 includes the following structure fields:
1400 - AVFormatContext.title
1401 - AVFormatContext.author
1402 - AVFormatContext.copyright
1403 - AVFormatContext.comment
1404 - AVFormatContext.album
1405 - AVFormatContext.year
1406 - AVFormatContext.track
1407 - AVFormatContext.genre
1410 - AVProgram.provider_name
