|
parameters to it. |
|
|

2009-10-07 - r20189 - lavfi 0.5.1 - AVFilterPic |

Add w and h fields to AVFilterPic. |
|
|
|
2009-06-22 - r19250 - lavf 52.34.1 - AVFormatContext.packet_size |
|
This is now an unsigned int instead of a signed int. |
|
|
|
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
