Release Notes
=============
* 0.7 "The Big Bump" June, 2011
* 0.8 "Forbidden Fruit"
General notes
-------------
This release enables frame-based multithreaded decoding for a number of codecs,
including VP8, H.263 and H.264. Additionally, there has been a major cleanup of
both internal and external APIs. For this reason, the major versions of all
libraries have been bumped. On the one hand, this means that 0.7 can be installed
side-by-side with previous releases, on the other hand, in order to benefit
from the new features, applications need to be recompiled.
Other important changes are additions of decoders including, but not limited to,
AMR-WB, single stream LATM/LOAS, G.722 ADPCM, a native VP8 decoder
and HE-AACv2. Additionally, many new de/muxers such as WebM in Matroska, Apple
HTTP Live Streaming, SAP, IEC 61937 (S/PDIF) have been added.
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. 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.
