17. April 2007: libquicktime-1.0.0 released
Finally we made 1.0.0 happen. Libquicktime can now be considered
finished with respect to core functionalities. Future versions will
mostly contain more codecs and bugfixes.
New in this release:
26. August 2006: libquicktime-0.9.10 released
- Support for text tracks. These can be either Subtitles or Chapters.
- Lots of fixes
- gettext support, German translation.
This is a bugfix release, no new features were added.
29. June 2006: libquicktime-0.9.9 released
- Fixed writing of compressed frames. This is an important feature
for dvgrab and kino.
- Fixed seeking for some codecs
- The sourcetree and CVS got cleaned up
27. January 2006: libquicktime-0.9.8 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
- 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
- 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
- Much more and better organized/documented ffmpeg encoding options.
- Support for multipass encoding. Multipass enabled encoders are
ffmpeg and x264.
This release brings lots of internal cleanups,
Doxygen-documentation and some new codecs. Many thanks to all contributors.
26. May 2005: libquicktime-0.9.7 released
- 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).
Another bugfix iteration. This time featuring:
21. May 2005: libquicktime-0.9.6 released
- Many compilation fixes for gcc4
- Better detection for CPU specific gcc flags
Another bugfix iteration. This time featuring:
15. May 2005: libquicktime-0.9.5 released
- Fixes for NetBSD 2.0

- Compilation should now happen without a single gcc warning
This is mostly a bugfix release, no major new features were added
Thanks to all people who reported problems and suggested fixes.
12. Jan 2005: libquicktime-0.9.4 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.
19. July 2004: libquicktime-0.9.3 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
- We also decode AVIs, but mostly our own ones.
- Some encoders were disabled to prevent spreading of horribly
- 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
20. June 2004: New website online
- 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.
- Decoding support for compressed headers and Sorenson 3
- 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.
New releases can also be expected soon.
