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. |
