release. Please see the file doc/APIchanges for details along with release. Significant API changes include:
* new audio decoding API which decodes from an AVPacket to an AVFrame and
is able to use AVCodecContext.get_buffer() in the similar way as video decoding.
* new audio encoding API which encodes from an AVFrame to an AVPacket, thus
allowing it to properly output timing information and side data.
* rewritten AVOptions API with better built-in support for private options.
* private options support for demuxers [avformat_open_input()], muxers
[avformat_write_header()], encoders and decoders [avcodec_open2()].
As a result, many format- or codec-specific fields and flags in AVFormatContext
and AVCodecContext were deprecated -- notably most of CODEC_FLAG2_* and many
CODEC_FLAG_*.
* new API for custom IO interrupt callbacks.
* #include cleanup in libavutil -- libavutil/avutil.h no longer includes all
the other headers in libavutil, they must be included manually. One specific
result is that libavutil/mathematics.h is no longer included from
libavcodec/avcodec.h, which is a common source of errors.

--------------------- ---------------------
Libavcodec and libavformat built as shared libraries now hide non-public
symbols. This will break applications using those symbols. Possible solutions
are, in order of preference:
1) Try finding a way of accomplishing the same with public API.
2) If there is no corresponding public API, but you think there should be,
post a request on the user mailing list or IRC channel.
3) Finally if your program needs access to FFmpeg / libavcodec / libavformat
internals for some special reason then the best solution is to link statically.
Please see the Changelog file for a more detailed list of changes. Please see the Changelog file for a more detailed list of changes.
