| 2009-06-19 - r19222 - lavc 52.32.0 - AVSubtitle.pts |
| Add a pts field to AVSubtitle which gives the subtitle packet pts |
| in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will |
| not work right without this. |
| |
| 2009-06-03 - r19078 - lavc 52.30.2 - AV_PKT_FLAG_KEY |
| PKT_FLAG_KEY has been deprecated and will be dropped at the next |
| major version. Use AV_PKT_FLAG_KEY instead. |
| |
| 2009-06-01 - r19025 - lavc 52.30.0 - av_lockmgr_register() |
| av_lockmgr_register() can be used to register a callback function |
| that lavc (and in the future, libraries that depend on lavc) can use |
| to implement mutexes. The application should provide a callback function |
| that implements the AV_LOCK_* operations described in avcodec.h. |
| When the lock manager is registered, FFmpeg is guaranteed to behave |
| correctly in a multi-threaded application. |
| |
| 2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet |
| av_free_packet() is no longer an inline function. It is now exported. |
| |
| 2009-04-11 - r18431 - lavc 52.25.0 - deprecate av_destruct_packet_nofree |
| Please use NULL instead. This has been supported since r16506 |
| (lavf > 52.23.1, lavc > 52.10.0). |
| |
| 2009-04-07 - r18351 - lavc 52.23.0 - avcodec_decode_video/audio/subtitle |
| The old decoding functions are deprecated, all new code should use the |
| new functions avcodec_decode_video2(), avcodec_decode_audio3() and |
| avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt |
| argument instead of a const uint8_t *buf / int buf_size pair. |
| |
| 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space |
| Introduce the av_fifo_space() function. |
| |
| 2009-04-02 - r18317 - lavc 52.23.0 - AVPacket |
| Move AVPacket declaration from libavformat/avformat.h to |
| libavcodec/avcodec.h. |
| |
| 2009-03-22 - r18163 - lavu 50.2.0 - RGB32 pixel formats |
| Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR, |
| PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values. |
| Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and |
| PIX_FMT_BGR32_1 are now macros. |
| avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases. |
| Re-sort the enum PixelFormat list accordingly. |
| This change breaks API/ABI backward compatibility. |
| |
| 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants |
| Add the enum PixelFormat values: |
| PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE, |
| PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE. |
| |
| 2009-03-21 - r18116 - lavu 50.0.0 - av_random* |
| The Mersenne Twister PRNG implemented through the av_random* functions |
| was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions |
| instead. |
| |
| 2009-03-08 - r17869 - lavu 50.0.0 - AVFifoBuffer |
| av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped |
| and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write |
| and av_fifo_realloc2. |
| In addition, the order of the function arguments of av_fifo_generic_read |
| was changed to match av_fifo_generic_write. |
| The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by |
| applications, they may not use sizeof() or directly access members. |
| |
| 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API |
| Introduce a new metadata API (see av_metadata_get() and friends). |
| The old API is now deprecated and should not be used anymore. This especially |
| includes the following structure fields: |
| - AVFormatContext.title |
| - AVFormatContext.author |
| - AVFormatContext.copyright |
| - AVFormatContext.comment |
| - AVFormatContext.album |
| - AVFormatContext.year |
| - AVFormatContext.track |
| - AVFormatContext.genre |
| - AVStream.language |
| - AVStream.filename |
| - AVProgram.provider_name |
| - AVProgram.name |
| - AVChapter.title |
