Frame rate from mediastreamvalidator

I noticed that the frame rate being reported by mediastreamvalidator is slightly higher than expected for my streams. For example, instead of 30Hz it reports 30.337, instead of 60Hz it reports 60.335. Has anyone else seen this? How is it calculating the frame rate?


I checked the frame rate for one of the .ts files in Interra's Vega Analyzer and it was 30.0000 Hz expected.


Thanks,

Phil
