I have seen some [examples](https://stackoverflow.com/questions/5808557/avassetwriterinputpixelbufferadaptor-and-cmtime) [of](https://stackoverflow.com/questions/5396800/help-me-understand-cmtime-in-avassetwriter) [CMTime](https://stackoverflow.com/questions/4001755/trying-to-understand-cmtime-and-cmtimemake) (Three separate links), but I still don&#39;t get it. I&#39;m using an AVCaptureSession with AVCaptureVideoDataOutput and I want to set the max and min frame rate of the the output. My problem is I just don&#39;t understand the CMTime struct.

Apparently CMTimeMake(value, timeScale) should give me value frames every 1/timeScale seconds for a total of value/timeScale seconds, or am I getting that wrong?

Why isn&#39;t this documented anywhere in order to explain what this does?

If it does truly work like that, how would I get it to have an indefinite number of frames?

If its really simple, I&#39;m sorry, but nothing has clicked just yet.

Trying to understand CMTime

This may seem ridiculous, but how can I output the seconds of CMTime to the console in Objective-C? I simply need the value divided by the timescale and then somehow see it in the console.
