2008-05-09 WhackedTV (HTML) (DMG) (ZIP)
Fixed two bugs: (1) "Select Output Format" in the audio dialog failed with error -206 if the source audio were set to 20 or 24 bits on an Intel Mac. The source format is 24-bits aligned low in 32-bits. WhackedTV was setting this as the default output format. But QuickTime movies can only contain packed samples. Added a utility function to conform the output format for movie-safety. (2) Began preferring the kQTSGAudioPropertyID_CodecSpecificSettingsArray property to the kQTSGAudioPropertyID_MagicCookie property. See QuickTimeComponents.h for an explanation of the differences between these properties, and why CodecSpecificSettingsArray should always be preferred over MagicCookie.
