版本历史 VirtualDub 1.3

[misc changes]

• Inverse telecine has been disabled. It\'s not working nearly as well on various sources as I\'d hoped, and so I\'ve disabled it until I have time to fix it.

[features added: main program]

• Direct support for YUY2 in both processing and capture modes.
• VirtualDub can now detect when files are about to exceed available disk space and/or the 4Gb FAT32 limit, and close the file before the limit.
• Replaced puny OS audio compression dialog with better, BIGGER one.

[features added: capture]

• Capture: Implemented video clock adjustment in capture mode for better audio/video sync.
• Capture: Fast field swap (RGB, YUY2, UYVY, YVYU).
• Capture: Fast noise reduction (RGB8, RGB24, RGB32, YUY2, UYVY, YVYU). (Algorithm courtesy of Steven Don).
• Capture: Fast 2:1 linear and cubic vertical reduction (RGB8, RGB24, RGB32, YUY2, UYVY, YVYU).
• Capture: CPU usage detection works in Windows NT/2K.

[optimizations]

• Added MMX IDCT routine to MPEG-1 and MJPEG decoding.
• MJPEG decoding significantly faster.

[bug fixes: main program]

• MJPEG mode selections no longer crash if the video isn\'t in MJPEG format.
• Internal MJPEG decoder now handles output from PICVideo and recent Morgan MJPEG codecs.
• Fixed video filter API causing filters to occasionally receive timestamps in us instead of ms.
• Fixed MPEG-1 packet sync errors caused by improper handling of sequence end tags.
• Fixed slight bias in MPEG-1 motion prediction.
• Fixed MPEG-1 macroblock skipping at slice start [fixes KareKano op].
• Fixed video compressor confusion when two codecs of the same format are installed under different FOURCCs (e.g. PICVideo and MainConcept).
• Fixed intermittent file write corruption on NT/2K SMP systems.
• Filters deinitialized on exit (thanks Joey Liaw).
• Hitting Cancel on the audio compression dialog no longer disables audio compression.
• Jobs with extended open options work.
• Smoother filter saves noise prefilter option.
• Fixed some miscellaneous \"Unhandled Microsoft C++ Exception\" crashes that were supposed to be errors.
• Fixed audio segments getting dropped during preview whenever the pipeline stalled temporarily.
• Fixed the stupid crash requester not saving crashinfo files.

[bug fixes: capture]

• Fixed capture \'audio relative rate\' value going negative.
• Fixed not being able to disable \'stupid capture driver\' settings in preferences.
• Allocate disk space dialog properly shows current capture drive.
• Disk space measurement works with UNC network paths.
• Segments can now exceed 2Gb.
• Fixed seek timing errors introduced in capture files with compressed audio.
• No longer crashes when running out of spill drives.
• Fixed crashing problems when using the \'save compression\' option with [No compression] or codecs that are later removed.
