Hi Brad..

For us vdig driver writers,

I'd like to see Generic GetInfo SetInfo selectors for the vdig components.

(Something like the way the Data Handlers work.. ie: DataHGetInfo )

I have had the need to access custom "one of a kind" hardware controls, and there

was no easy way to interact with the device via vdig.

The only way was to come up with some code to create "custom selectors", and there is virtually

no documentation on how to implement your own, even though this seems to be possible..

Heheh, yes, I will file an enhancement request into the black hole. (ahem.. ) I mean bugreporter.. :)

On a positive note, Quicktime capture API's are somewhat in flux at
the moment -- QTKit capture was introduced last WWDC. As we
modernize our capture API's and implementation, we are definitely
looking to shore up the Sequence Grabber's current inadequacies, and
we do recognize the lack of modern closed captioning API as one of
those shortcomings.

At the same time, I'd like to raise my hand and say "API for data code extraction, please"...data code, the video equivalent of EXIF in DV, DVCAM, DVCPRO, and HDV--precise time of day, camera aperture and shutter info, and so on--is increasingly important, as is, of course, the associated timecode.

This is a great request. Please log it as an enhancement request bug at bugreport.apple.com to make sure someone is ultimately made responsible for looking at it and thinking about it.
