Bug Report Avermedia weird fps settings? and memory leak!

[Dariofubar]

Hey, i just wanted to ask if there is a reason that i can only select 60.0002 fps and not just 60 (is this just a display bug or something that might have an impact on performance )? When i compare it to xsplit i can normally select 60fps @ 720p when i configure the device (avermedia live gamer hd) in the sources selection.

device: AVerMedia HD Capture C985 Bus 4,
device id \\?\pci#ven_1af2&dev_a001&subsys_a0011af2&rev_00#4&256f5a3a&0&00e3#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\{957bd672-7934-4b55-b81a-3e22b14c679a},
chosen type: YV12, usingFourCC: true, res: 1280x720 - 1280x720, fps: 15-60.0002, fourCC: 'YV12'

additionally i got a random log where it only states "Memory leaks were detected" and nothing else(this is with the most recent stable version v0.472b).

Also , whenever i alt tab out or into a game with the Capture card as source selected i am dropping frames , this only appears during the alt tabbing time window . in a game everything is allright.

here is a random log where everything was normal apart from the dropped frames during the alt tab process

The 60.0002 is fine, you can safely ignore it, it's just a floating point precision thing for when converting the frame time interval, when you set it the app ensures that it will use the correct interval regardless of what it displays.

There is a minor memory leak somewhere (harmless), I have yet to pinpoint it, but if you can figure out how to make it happen every time, I would be grateful.

If you're dropping frames when switching scenes, you should consider using your device as a global source instead of as a regular source, a global source stays on for the duration of the stream so it doesn't have to turn off/on ever again until the stream ends, prevents device lag from doing so.

Thank you for your friendly and fast explanation. I will do my best to fiddle around how to recreate the memory leak. Thank you Jim, you are awesome!!!!!!!
