@ -9,10 +9,7 @@ General notes
This release continues the API cleanups that have begun with the
previous release. While it is binary compatible with 0.7, many parts of
the public API were deprecated and will be removed in the git master and
later releases. Note that a couple of header includes have been cleaned
up, which may require code changes in your applications. In particular,
the header "libavutil/mathematics.h" is no longer included from
"libavcodec/avcodec.h". Please consult the doc/APIchanges file to see
later releases. Please consult the doc/APIchanges file to see
intended replacements for the deprecated APIs.
Furthermore, our work on the 'ffmpeg' command-line tool has resulted in

A number of additional APIs have been introduced and some existing
functions have been deprecated and are scheduled for removal in the next
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.
Please see the file doc/APIchanges for details along with
similar programmer-centric information.
