[Development] No way to set the framerate of QCamera

[Tobias Haslop]

Nevermind, for some reason I was not able to read the docs properly:

If the minimum frame rate is equal to the maximum frame rate, the frame rate is fixed. If not, the actual frame rate fluctuates between the minimum and the maximum.

Sorry

Subject: No way to set the framerate of QCamera


Hello,


I want to implement a backend for SVS-Vistek Gigabit Ethernet cameras, but I see no way to set the camera's framerate.

There is the FrameRateRange, but I am not sure about its meaning:

Does setting a framerate range guarantee for each consecutive frame to arrive in a certain timespan?

Or does a supported framerate range mean that framerates in that range can be set?

My intuition was the latter, but after not being able to find a hint how to set the framerate I am starting to believe it is the first meaning.


The SVS-Vistek API allows me to query framerate range and step as well as to set the framerate directly and I do not want to miss that ability.

I guess adding a custom control to set the framerate is an option for me, but before I do that I want to be sure that I did not miss anything.


Thanks,

Tobias
