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. |
|
|
|
