294 'CodecID' identifier. Such code should either #undef CodecID or stop using the
295 CodecID name.

355 For audio formats with fixed frame size, the last frame
356 no longer needs to be padded with silence, libavcodec
357 will handle this internally (effectively all encoders

1317 Introduce the avfilter_next() function.
1318
1319 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
1320 Change the signature of avfilter_register() to make it return an

1324 Make the pixdesc.h API public.

1347
1348 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
1349 Add a pts field to AVSubtitle which gives the subtitle packet pts
1350 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
1351 not work right without this.
1352
1353 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
1354 PKT_FLAG_KEY has been deprecated and will be dropped at the next

1356
1357 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
1358 av_lockmgr_register() can be used to register a callback function
1359 that lavc (and in the future, libraries that depend on lavc) can use
1360 to implement mutexes. The application should provide a callback function
1361 that implements the AV_LOCK_* operations described in avcodec.h.
1362 When the lock manager is registered, FFmpeg is guaranteed to behave
1363 correctly in a multi-threaded application.
1364
1365 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
1366 av_free_packet() is no longer an inline function. It is now exported.
1367
1368 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
1369 Please use NULL instead. This has been supported since r16506
1370 (lavf > 52.23.1, lavc > 52.10.0).
1371
1372 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
1373 The old decoding functions are deprecated, all new code should use the
1374 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
1375 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
1376 argument instead of a const uint8_t *buf / int buf_size pair.
1377
1378 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()

1383 libavcodec/avcodec.h.
1384
1385 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
1386 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
1387 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
1388 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
1389 PIX_FMT_BGR32_1 are now macros.
1390 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
1391 Re-sort the enum PixelFormat list accordingly.
1392 This change breaks API/ABI backward compatibility.
1393
1394 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
1395 Add the enum PixelFormat values:
1396 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
1397 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
1398
1399 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
1400 The Mersenne Twister PRNG implemented through the av_random* functions
1401 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
1402 instead.
1403
1404 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
1405 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
1406 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
1407 and av_fifo_realloc2.
1408 In addition, the order of the function arguments of av_fifo_generic_read
1409 was changed to match av_fifo_generic_write.
1410 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
1411 applications, they may not use sizeof() or directly access members.
1412
1413 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
1414 Introduce a new metadata API (see av_metadata_get() and friends).
1415 The old API is now deprecated and should not be used anymore. This especially
1416 includes the following structure fields:
1417 - AVFormatContext.title
1418 - AVFormatContext.author
1419 - AVFormatContext.copyright
1420 - AVFormatContext.comment
1421 - AVFormatContext.album
1422 - AVFormatContext.year
1423 - AVFormatContext.track
1424 - AVFormatContext.genre
1425 - AVStream.language
1426 - AVStream.filename
1427 - AVProgram.provider_name
1428 - AVProgram.name
1429 - AVChapter.title
