i.MX8 camera out fps question

[xu_ji1]

Hi,

I used i.MX8QM platform and in camera driver changed "streamcap.timeperframe.denominator" this value to 15 or 60

but why use application get camera output frame rate always 30?

If I want to diff camera frame rate output,what need changed or i.MX8 lock it 30?

Hi Xu

seems  frame rate is defined in driver described in

Table 6-5. Omnivision V4L2 Camera Driver Files attached Linux Manual,

like "#define DEFAULT_FPS" in driver code:

ov5640_mipi_v3.c\imx8\platform\media\drivers - linux-imx - i.MX Linux kernel 

Best regards
igor

Hi,

I also try to change this value #define DEFAULT_FPS 15 or 60,but fps not changed

The camera fps depends on camera register config，platform can support 60fps
