Small point, the article mentions Apple's QuickTime as the first software only video system.

I seem to remember at the time that Acorn's Replay video codec had been around for a few years prior to QuickTime.

Replay was designed by Sophie Wilson who also designed the original ARM instruction set whilst at Acorn.

Nice info.

The article mention 3 SDKs, 10.6 10.8 and 10.10, what is the oldest Mac OS version allowing to use the Video Toolbox framework ?

Will using the higher level API AV foundation also give hardware acceleration ?

There are 2 links at the end of the article but you can only download them if you went to WWDC…

The title should perhaps mention that it's about video decoding.

I badly need this info! Thanks
