Video upgrade becomes critical for OSX/linux

Status: New

With the release of labview 2016 the issue of cross-platform support for video becomes critical.

 

As stated in the "features and changes" page: "NI no longer provides the 32-bit version of LabVIEW for OS X."

 

Up to now it was possible to use Christophe Salzmann's QTLib to work with video. This was great software because the very same "universal" VIs ran on Windows and OSX systems. However, this tool relied on QuickTime. QuickTime is 32-bit and will not evolve to 64-bit (it has been replaced by newer libraries), and so does QTLib.

 

Thus all the code developed with labview including cross-platform video handling cannot be maintained and developed!

 

On the other hand, video is becoming an ubiquitous feature in computer technologies, from mobile apps, to IT, to big data and deep learning. It is a strategic time to push for video on labview across all platforms. It is time for video handling VIs to appear in the standard dev package, just as jpeg or png read/write VIs were added after photos massively entered the computer world.

 

I propose the addition in the "Programming/Graphics&Sound" palette of a subset of VIs for handling video (open video file for read or write, read file frame by frame, append one frame to file, grab frames from webcam). There is no doubt that such feature will be valuable in a future labview release!
