  286. avfilter_make_format_list(enum PixelFormat *pix_fmts).
  287. 2009-10-18 - r20272 - lavfi 1.0.0 - avfilter_get_video_buffer()
  288. Make avfilter_get_video_buffer() recursive and add the w and h
  289. parameters to it.
  290. 2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic
  291. Add w and h fields to AVFilterPic.
  292. 2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size
  293. This is now an unsigned int instead of a signed int.
  294. 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts
  295. Add a pts field to AVSubtitle which gives the subtitle packet pts
  296. in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
  297. not work right without this.
  298. 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY
  299. PKT_FLAG_KEY has been deprecated and will be dropped at the next
  300. major version. Use AV_PKT_FLAG_KEY instead.
  301. 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register()
  302. av_lockmgr_register() can be used to register a callback function
  303. that lavc (and in the future, libraries that depend on lavc) can use
  304. to implement mutexes. The application should provide a callback function
  305. that implements the AV_LOCK_* operations described in avcodec.h.
  306. When the lock manager is registered, FFmpeg is guaranteed to behave
  307. correctly in a multi-threaded application.
  308. 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
  309. av_free_packet() is no longer an inline function. It is now exported.
  310. 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
  311. Please use NULL instead. This has been supported since r16506
  312. (lavf > 52.23.1, lavc > 52.10.0).
  313. 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
  314. The old decoding functions are deprecated, all new code should use the
  315. new functions avcodec_decode_video2(), avcodec_decode_audio3() and
  316. avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
  317. argument instead of a const uint8_t *buf / int buf_size pair.
  318. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()
  319. Introduce the av_fifo_space() function.
  320. 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket
  321. Move AVPacket declaration from libavformat/avformat.h to
  322. libavcodec/avcodec.h.
  323. 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats
  324. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  325. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  326. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  327. PIX_FMT_BGR32_1 are now macros.
  328. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  329. Re-sort the enum PixelFormat list accordingly.
  330. This change breaks API/ABI backward compatibility.
  331. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
  332. Add the enum PixelFormat values:
  333. PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
  334. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  335. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*
  336. The Mersenne Twister PRNG implemented through the av_random* functions
  337. was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
  338. instead.
  339. 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer
  340. av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
  341. and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
  342. and av_fifo_realloc2.
  343. In addition, the order of the function arguments of av_fifo_generic_read
  344. was changed to match av_fifo_generic_write.
  345. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  346. applications, they may not use sizeof() or directly access members.
  347. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  348. Introduce a new metadata API (see av_metadata_get() and friends).
  349. The old API is now deprecated and should not be used anymore. This especially
  350. includes the following structure fields:
  351. - AVFormatContext.title
  352. - AVFormatContext.author
  353. - AVFormatContext.copyright
  354. - AVFormatContext.comment
  355. - AVFormatContext.album
  356. - AVFormatContext.year
  357. - AVFormatContext.track
  358. - AVFormatContext.genre
  359. - AVStream.language
  360. - AVStream.filename
  361. - AVProgram.provider_name
  362. - AVProgram.name
  363. - AVChapter.title
