Luca Barbato ce70f28a17 avpacket: Replace av_free_packet with av_packet_unref

av_lockmgr_register() can be used to register a callback function
that lavc (and in the future, libraries that depend on lavc) can use

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 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
av_free_packet() is no longer an inline function. It is now exported.

2009-04-07 - 7a00bba - 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 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
Introduce the av_fifo_space() function.
2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket

libavcodec/avcodec.h.
2009-03-22 - 6e08ca9 - 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 - f82674e - 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 - ee6624e - lavu 50.0.0 - av_random*

was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
instead.
2009-03-08 - 41dd680 - 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 - ec26457 - 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
