General notes | |||
------------- | |||
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. | |||
@@ -32,7 +31,30 @@ 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. 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. | |||

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 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. |
