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. 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 -major revisions to its interface. In order to not break existing scripts -and applications, we have chosen to introduce a new tool called -'avconv', and keep the traditional 'ffmpeg' frontend for end-user's -convenience. Please see the Changelog file for details how 'avconv' -differs from 'ffmpeg'. - -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. - -See the Changelog file for a list of significant changes. - -Please note that our policy on bug reports has not changed. We still only accept -bug reports against HEAD of the Libav trunk repository. If you are experiencing -issues with any formally released version of Libav, please try a current version -of the development code 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 ------------ - -A number of additional APIs have been introduced and some existing -functions have been deprecated and are scheduled for removal in the next -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. - - - -Other notable changes ---------------------- - -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 Libav 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. +See the Changelog file for a list of significant changes. Note, there +are many more new features and bugfixes than whats listed there. + +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. |
