|
|
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
|
