Release Notes
|
|
=============
|
|
|
|
* 0.7 "The Big Bump" June, 2011
|
|
|
|
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.
|
|
|
|
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
|
|
-----------
|
|
|
|
Please see the file doc/APIchanges for programmer-centric information. Note that a
|
|
lot of long-time deprecated APIs have been removed. Also, a number of additional
|
|
APIs have been deprecated and are scheduled for removal in the next release.
