  299. 2009-12-05 - r20734 - lavfi 1.12.0 - avfilter_draw_slice()
  300. Add a slice_dir parameter to avfilter_draw_slice().
  301. 2009-11-26 - r20611 - lavfi 1.11.0 - AVFilter
  302. Remove the next field from AVFilter, this is not anymore required.
  303. 2009-11-25 - r20607 - lavfi 1.10.0 - avfilter_next()
  304. Introduce the avfilter_next() function.
  305. 2009-11-25 - r20605 - lavfi 1.9.0 - avfilter_register()
  306. Change the signature of avfilter_register() to make it return an
  307. int. This is required since now the registration operation may fail.
  308. 2009-11-25 - r20603 - lavu 50.5.0 - pixdesc.h API
  309. Make the pixdesc.h API public.
  310. 2009-10-27 - r20385 - lavfi 1.5.0 - AVFilter.next
  311. Add a next field to AVFilter, this is used for simplifying the
  312. registration and management of the registered filters.
  313. 2009-10-23 - r20356 - lavfi 1.4.1 - AVFilter.description
  314. Add a description field to AVFilter.
  315. 2009-10-19 - r20302 - lavfi 1.3.0 - avfilter_make_format_list()
  316. Change the interface of avfilter_make_format_list() from
  317. avfilter_make_format_list(int n, ...) to

  320. Make avfilter_get_video_buffer() recursive and add the w and h
  321. parameters to it.
  322. 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
  323. Add w and h fields to AVFilterPic.
  324. 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
  325. This is now an unsigned int instead of a signed int.
  326. 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
  327. Add a pts field to AVSubtitle which gives the subtitle packet pts
  328. in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
  329. not work right without this.
  330. 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
  331. PKT_FLAG_KEY has been deprecated and will be dropped at the next
  332. major version. Use AV_PKT_FLAG_KEY instead.
  333. 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
  334. av_lockmgr_register() can be used to register a callback function
  335. that lavc (and in the future, libraries that depend on lavc) can use
  336. to implement mutexes. The application should provide a callback function
  337. that implements the AV_LOCK_* operations described in avcodec.h.
  338. When the lock manager is registered, FFmpeg is guaranteed to behave
  339. correctly in a multi-threaded application.
  340. 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
  341. av_free_packet() is no longer an inline function. It is now exported.
  342. 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
  343. Please use NULL instead. This has been supported since r16506
  344. (lavf > 52.23.1, lavc > 52.10.0).
  345. 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
  346. The old decoding functions are deprecated, all new code should use the
  347. new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  348. avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  349. argument instead of a const uint8_t *buf / int buf_size pair.
  350. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
  351. Introduce the av_fifo_space() function.
  352. 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
  353. Move AVPacket declaration from libavformat/avformat.h to
  354. libavcodec/avcodec.h.
  355. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
  356. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  357. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  358. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  359. PIX_FMT_BGR32_1 are now macros.
  360. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  361. Re-sort the enum PixelFormat list accordingly.
  362. This change breaks API/ABI backward compatibility.
  363. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  364. Add the enum PixelFormat values:
  365. PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  366. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  367. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
  368. The Mersenne Twister PRNG implemented through the av_random* functions
  369. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  370. instead.
  371. 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
  372. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  373. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  374. and av_fifo_realloc2.
  375. In addition, the order of the function arguments of av_fifo_generic_read
  376. was changed to match av_fifo_generic_write.
  377. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  378. applications, they may not use sizeof() or directly access members.
  379. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  380. Introduce a new metadata API (see av_metadata_get() and friends).
  381. The old API is now deprecated and should not be used anymore. This especially
  382. includes the following structure fields:
  383. - AVFormatContext.title
  384. - AVFormatContext.author
  385. - AVFormatContext.copyright
  386. - AVFormatContext.comment
  387. - AVFormatContext.album
  388. - AVFormatContext.year
  389. - AVFormatContext.track
  390. - AVFormatContext.genre
  391. - AVStream.language
  392. - AVStream.filename
  393. - AVProgram.provider_name
  394. - AVProgram.name
  395. - AVChapter.title
