- 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.
-
- Bugreports against FFmpeg git master or the most recent FFmpeg release are
- accepted. If you are experiencing issues with any formally released version of
- FFmpeg, please try git master to check if the issue still exists. If it does,
- make your report against the development code following the usual bug reporting
- guidelines.

- Note, if you have difficulty building for mingw, try --disable-outdev=sdl
