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 V39 (included)
recommended hardware requirements:
-Amiga with AmigaOS 3.1 (V40)
-MC68040 at 25MHz minimum
-graphic board with CyberGraphX 2.21 or higher

Changes since V1.1:
- fixed some problems with oversized audio samples, although audio playback
may still stumble a bit (happened with trailer to "Aliens 2")
- added support for PCM0 audio encoding
- window on public screen is now resizeable on special request by Thomas
Börkel :)
- fixed bad bug in RAW32 decoder
- added some frame size checks to avoid crashes with corrupted frames
- fixed some problems with resource fork recognition
- fixed some problems with multi video tracks and different encodings
- BIG speed improvement when converting YUV -> RGB in grayscale mode
- fiddled around with depth selection of animation with mixed truecolor and
colormapped encodings. I hope it is correct now.
- did many changes on timing calculations
- audio samples are now buffered in a queue instead of playing them directly.
Thus playback should not stumble anymore if audio and video data are
interleaved.
- animations with more audio frames than video frames per second are now
played correctly again
- animations with with very small audio samples (eg. one sample per frame
instead of one sample per 5 frames) are now more often played correctly.
Playback may still listen bad because of too much overhead with these very
small samples.
- decoding of mono audio samples sped up by using just one buffer instead of
two. Two buffers are now used for stereo samples only.
- added option AUDIOPRELOAD, which enables decoding of all audio samples
before playback, to keep playback smooth with slow harddisks or
non-interleaved animations.
- fixed bug with PCM0 decoder
- finally made animations with old style STSC chunk work
- CyberQT now handles samples of ANY size. There is no limit of 128K per
sample for audio.device anymore.
- fixed bug when animations with and without sound were played within one
call of CyberQT (eg selected via requester)
- fixed bug with RLE1 decoder, RLE4 decoder was called accidentially
- fixed bug with wrong grayscale palette for CVID animations
- fixed bug with TWOS 16bit stereo audio that occured when reading sample
sizes
- changed FPS rate in stats from integers to floats to be more precise
- added option MAGNIFY to allow scaling of the display window on public by
factors of 1..4
- CVID decoder produced wrong pixel blocks in grayscale mode. This is fixed
now.
- CyberQT got a new icon. Much thanks to Bastian Kinne for painting it.
- added option DITHER for ordered dithering with AGA
- optimized checks for corrupted files. Truncated files are not always
rejected, but recognized.
- did some optimizations for RPZA dithering, looks better now
- hopefully fixed the last elst-chunk problems
