General notes
|
|
-------------
|
|
|
|
This release enables frame-based multithreaded decoding for a number of codecs,
|
|
including theora, huffyuv, VP8, H.263, mpeg4 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 except libpostproc have been bumped. This means that 0.8 can be installed
|
|
side-by-side with previous releases, on the other hand applications need to be
|
|
recompiled to use 0.8.
|
|
|
|
Other important changes are more than 200 bugfixes, known regressions were fixed
|
|
w.r.t 0.5 and 0.6, 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.
