CyberQT is a fast QuickTime animation player for 020+ machines with AmigaOS 3.0
or higher and a graphic board with CyberGraphX or AGA.
minimum hardware requirements:
-Amiga with AmigaOS 3.0 (V39)
-MC68020
-graphic board with CyberGraphX (eg. CyberVision64, Picasso II, Retina, etc)
or AGA chipset
-2MB of FastRAM, 512K of ChipRAM
software requirements
-CyberGraphX 2.21 or higher (if used with a graphic board)
-asyncio.library V38 (included)
recommended hardware requirements:
-Amiga with AmigaOS 3.1 (V40)
-MC68040 at 25MHz minimum
-graphic board with CyberGraphX 2.21 or higher

CyberQT is Copyright (c)1996-1997 by Thore Boeckelmann.
Changes since V1.0:
- fixed a bug in RPZA decoder with AGA that produced wrong pixels/blocks of
pixels
- fixed "too slow video playback" when video timescale is not equal to anim
timescale
- fixed delayed reaction when changing playback speed
- CVID depth 32 is now supported, too
- added support for IMA4 audio compression. Unfortunately I was not able to
test IMA4's stereo part because of no animation of that kind
- improved handling of multi-track QTs
- implemented SKIP option to skip delayed frames and keep audio playback
synchronous
- fixed sound loop bug when playing more than one animation at a time.
Reported by Thomas Börkel and many other people.
- improved error handling in "out of memory" situations
- added support for KPCD video compression. Thanks to Lars Weigl for his NASA
animation.
- fixed bug that made playback stuck because of wrong calculated time offsets
- fixed bug with wrong interpreted elst chunks
- small speed improvement for KPCD
- hopefully fixed last problems with screenmode selection.
eg: 240x300 animations should be shown on a 640x480 screen instead of a
320x240 screen.
- fixed some skippinig problems with "keyframe-only" QTs
- fixed problems with TWOS 16bit stereo sound. SamplesPerChunk entry was
misinterpreted as "bytes per chunk" instead of real "samples per chunk", so
not enough data were read.
