Sub page list:
Version 0.97
- 64 Bit x86 and ARM64 (M1/M2) port (10.9+)
- disabled Quicktime export function (QT was Carbon and not available in 64 Bit)
- disabled true Fullscreen feature (for now)
- known issue: OpenGL double buffering sometimes fails on 120Hz screens
version 0.96
- implemented Y4M file format support (except 4:1:1)
- YCbCr4:4:4 8 Bit planar support
- Y only (4:0:0) 8 Bit support
- 10 Bit UYVY support in big endian notation
- option to disable automatic multi-file concatenation in open dialog
- [Bugfix] fixed missing 4:2:2 planar mode for conversion/SSIM calculation
- [Bugfix] copy to clipboard fix for Snow Leopard
- added 1920x1088 to auto-detect list
- several other bug fixes
version 0.95
- Snow Leopard compatibility
- implemented support for YUV 4:0:0 (Luma only), 8 Bit
- additional file extensions .yuv8, .yuv16 plus ability to change the default list by editing the GLYUVPlay.plist file
version 0.94
- restored MacOS 10.3 compatibility
- new display options in fullscreen mode: text labels for file name, dimensions, PSNR, SSIM
- implemented Recent menu
- new display zoom options: 1:1 pixel accurate, fit, zoom (direct selection via shortcut keys "1","2","3")
- Fixed RAW export amplitude scaling when attempting 1:1 copy
version 0.93
- fixed rare endless loop in open dialog
- automatic resolution/color depth detection now supports segmented (multiple files) sequences
- slight performance improvement (Y,Cb,Cr masking entirely skipped when not in use)
- implemented SSIM (structural similarity), original method and video method
- added technical documentation about the internal image processing methods
- bumped the max. filter length in scaling routine to 64 taps (roughly sufficient to properly downscale 1080p into QCIF)
version 0.91
- fixed hang/crash in Open Dialog on PowerPC machines
- fixed split view divider refresh issues on MacOS 10.4
version 0.9
- support for multiple input formats in 8/10 Bit and YCbCr 4:2:0, 4:2:2
- support for SGI files (8/16 Bit RGB)
- loading of segmented YUV files (enumerated single files, automatic detection)
- RAW export in various formats/depths
- preferences dialog / automatically remembers the settings
- PSNR display for U, V, PSNR text boxes can be disabled via split view divider

Version 0.8
- added ability to double-click YUV files in Finder
- added file name(s) to title bar
- added "export" option to convert loaded YUV files to Quicktime, AVI, etc.
- added "copy" command (Command+C or menu), which exports the currently selected image as TIFF to other applications
Version 0.7
- complete internal restructuring of sequence handling, positioning and display to pave a way for future features
- fixed multi-window support
- added ability to select left/right display slot in file selector
- Macroblock number display now uses the OSX text system (antialiased)
- Macroblock number and magnified Macroblock move out of the way whenever the mouse pointer is nearing
- PSNR is indicated in the frame number slider by a color bar (RED=20 dB and below, YELLOW=25 dB, GREEN=30 dB and better, BLUE=perfect match)
- in play mode, the number of frames per second is selectable
- changed scaling of displayed sequences from linear to "nearest neighbor" in order to identify individual pixels better
- released the source code for this version, license: GPL V2
Version 0.6
- compiled as universal binary, runs native on Intel processors
- added image preview to open dialog for instant verification of correct image dimensions
- indicator for matching frames and average PSNR whether calculations are finished or not
Version 0.5
- initial public release
