RELEASE_NOTES: remove possibly ofensive sounding wording from after the merge that i missed and do other general cleanup Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

This release is binary compatible with 0.8. The 'ffmpeg' command-line tool has
been extended to also support the command line syntax and features of a tool
called avconv.
Prepare for 0.8_beta1 snapshot release

Additionally, this release introduces a number of new interesting codecs
such as the Apple Prores, Flash Screen Video 2 and Windows Media Image,
and muxers such as LATM or CELT in Ogg, among many others. Moreover, our
H.264 decoder has been improved to decode 4:2:2 material and our libx264
wrapper now allows to produce 4:2:2 and 4:4:4 video.

Bugreports against FFmpeg git master or the most recent FFmpeg release are
accepted. If you are experiencing issues with any formally released version of
FFmpeg, please try git master to check if the issue still exists. If it does,
make your report against the development code following the usual bug reporting
guidelines.

API changes
-----------
Prepare for 0.8_beta1 snapshot release
2011-11-06 10:12:04 +00:00
A number of additional APIs have been introduced and some existing
functions have been deprecated and are scheduled for removal in the next
RELEASE_NOTES: mention some notable API changes in 0.8
2012-01-17 11:42:34 +00:00
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

Other notable changes
---------------------
RELEASE_NOTES: mention hiding private symbols in shared builds.
2012-01-17 12:38:35 +00:00
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.
