26. August 2006: libquicktime-0.9.10 released

This is a bugfix release, no new features were added.

Fixed writing of compressed frames. This is an important feature for dvgrab and kino.

29. June 2006: libquicktime-0.9.9 released

Read/Write support for: DVCPRO50 video, OpenDML AVIs, mp4/m4a files and Quicktime 7 lpcm audio
H.264 encoding using x264.
Greatly improved and tested file compatibility. Files created by libquicktime are known to be playable on the following players:
- Quicktime 7: mov files with AAC or LPCM audio and MPEG-4 ASP or H.264/AVC video. Multichannel informations are supported (and correctly recognized) as well. Furthermore, Quicktime 7 plays our .mp4 and .m4a files, without multichannel though. Reading/writing of iTunes metadata works as well. For video encoding, the recommendation is to use conservative codec settings. Savest is to start with the defaults and then explore what's supported.
- Windows Media Player: AVI with mp3 or sowt (16b bits uncompressed) audio and DivX (3.11 or 4+) video. Several hardware Divx players might be able to play our AVIs too. Not supported in AVI are B-frames and VBR audio. For ODML files, WMP plays only the first RIFF.
- Divx player: AVI with mp3 and DivX (3.11 or 4+). Slightly better ODML support.
Much more and better organized/documented ffmpeg encoding options.
Support for multipass encoding. Multipass enabled encoders are ffmpeg and x264.

27. January 2006: libquicktime-0.9.8 released
This release brings lots of internal cleanups, Doxygen-documentation and some new codecs. Many thanks to all contributors.

The colormodel converter was cleaned up and fixed. We now have 16 bit YUV formats and JPEG (full range) YUV
Support for 24 and 32 bit uncompressed audio.
New audio en-/decode functions allow you to bypass all internal sampleformat conversions and read/write audio with full resolution even for 24 and 32 bit.
A v210 codec (10 bit YCbCr 4:2:2)
More standardized for MPEG-4 video encoding
Encoding and decoding support of AAC audio
H.264 decoding support
High end audio codecs: 24 bit, 32 bit, floating point (32 and 64 bit)
Decoding of Alac (Apple lossless) audio streams.
Some internal simplifications: Colormodel conversions (for video) and sampleformat conversions (for audio) are now handled by the core rather than by the codecs.
API reference documentation (see here).

26. May 2005: libquicktime-0.9.7 released

All audio decoders should now decode up to the last sample.
Many smaller fixes
Header files are now installed into prefix/include/lqt to avoid conflicts with the native Quicktime API on OSX
RPMs are no longer distributed, but there is still a .spec file so you can make your own RPMs.

Thanks to all people who reported problems and suggested fixes. 12. Jan 2005: libquicktime-0.9.4 released

As always: Fewer bugs.
We now encode AVI files. For audio, you can use the mp3, sowt (uncompressed PCM) or ulaw codecs. For Video, you can use FFMPEG MSMpeg 4v3 (playable by the Divx codec on windows) or FFMPEG MJPEG. MJPEG AVIs are bidirectional compatible with blender.
We also decode AVIs, but mostly our own ones.
Some encoders were disabled to prevent spreading of horribly incompatible files
Support for reading and writing QuicktimeVR V1.0 object movies and single-node panoramas. Use lqtvrplay to test them.
En-/Decoding of Quicktime files with nonconstant framerates.
2vuy en-/decoding

19. July 2004: libquicktime-0.9.3 released

Many bugfixes and portability patches people sent over the time.
Some legacy codecs were replaced by ffmpeg codecs.
Build scripts for RPM and debian packages are available now.

New API extensions let you obtain accurate video timestamps for streams, which have no constant framerate. Encoding support for variable framerate streams will come later.

20. June 2004: New website online
New releases can also be expected soon.
