Hi,

gspca does not implement vidioc_enum_frameintervals yet, so even if a
camera can support multiple frame rates (or frame intervals) there is
still no way to enumerate them from userspace.

The following is just a quick and dirty implementation to show the
problem and to have something to base the discussion on. In the patch
there is also a working example of use with the ov534 subdriver.

Someone with a better knowledge of gspca and v4l internals can suggest
better solutions.



Does the ov534 driver actually support selecting a framerate from the
list this patch adds, and does it then honor the selection ?

The ov534 is a bridge for different sensor like ov538 so it support different
frame rate, depends on the sensor too.
