With this release, we +change our versioning scheme to follow our workflow better. This means that the +leading zero, present in our previous version numbers, is dropped. Version +numbers from now on will be in <i>major.minor</i> form, with major releases +updating the major component and stable releases the minor component. +</p> + +<p> +A new library arrived in Libav during this development cycle -- its name is +<b>libavresample</b> and it handles audio conversion and mixing. All +users are encouraged to use it instead of the old, now deprecated, audio +conversion API in libavcodec. +</p> + +<p> +The <b>libpostproc</b> library now resides in a separate tree. It was fully +independent of the other Libav libraries, not used by any of the tools, +and saw very little development. For these reasons we have decided that it +has no place in Libav. A standalone Git tree is available +at <a href="http://git.videolan.org/?p=libpostproc.git";>VideoLAN</a> for +people wishing to use libpostproc. +</p> + +<p> +The major versions of the <b>libavcodec</b>, <b>libavformat</b> +and <b>libavfilter</b> libraries have been bumped, so they are not API +or ABI compatible with the 0.8 release. +</p> + +<p> +This release brings a number of significant changes in +the <b>libavfilter</b> library. Firstly, all the API dealing with +filter internals is no longer public. The result is that creating +user-side filters will not be supported until libavfilter is more +mature. Secondly, full audio filtering support is now available along +with a set of basic audio filters. We hope that their number will soon +grow significantly. The avconv transcoding tool has of course been +extended to handle audio filtering as well. There were a number of +other API changes, most importantly the addition of the buffer sink +public API. +</p> + +<p> +In the <b>libavcodec</b> library, one of the most notable changes is +added support for planar audio (i.e. not interleaved). Many decoders and +encoders, which previously did inefficient (de)interleaving internally, +now <em>only work with planar audio formats</em>. Libavresample can be used for +optimized conversion between interleaved and planar formats. +</p> + +<p> +Of big interest to our Windows users, Libav now supports building with the MSVC +compiler. Since MSVC does not support C99 features used extensively by Libav, +this has been accomplished using a <a +href="https://github.com/libav/c99-to-c89/";>converter</a> that turns C99 code +to C89. See <a href="platform.html#Microsoft-Visual-C_002b_002b">here</a> for +more detailed documentation on building Libav with MSVC. +</p> + +<p> +As usual, this release also contains support for some new formats, many +smaller new features and countless bug fixes. We can highlight Opus +decoding / encoding through libopus, encoders for Apple ProRes and Ut +Video, 24-bit FLAC encoding, WMA Lossless and RealAudio Lossless decoders, +fragmented MOV/MP4 and ISMV (Smooth Streaming) muxers, a large number of RTMP +improvements and support for cover art in ID3v2, WMA, MP4 and FLAC. +</p> + +<p> +See the +<a href="https://git.libav.org/?p=libav.git;a=blob;f=Changelog;h=92098cacd5773f2fbae7b0452afe9f127b74852a;hb=HEAD";>Changelog</a> +file for a list of significant changes. +</p> + +<p> +You can download the new release, as usual, +from <a href="download.html#release9">our download page</a> +</p> + + <a name="9_beta3"></a><h3>December 21 2012</h3> <p> _______________________________________________ libav-commits mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-commits
