TDA3XEVM: Understanding the p command in VisionSDK Console

Hi,

What does it mean when I get something like this on ISSCAPTURE. I am interested in understanding the difference between "Get Full Buf Cb", "Put Empty Buf Cb" and "Driver/Notify Cb". When and Why there is a difference in fps? and what does it mean when there is a difference?

[IPU1-0] 151.041664 s: [ ISSCAPTURE ] Link Statistics,
[IPU1-0] 151.041755 s: ******************************
[IPU1-0] 151.041816 s:
[IPU1-0] 151.041847 s: Elapsed time = 9404 msec
[IPU1-0] 151.041938 s:
[IPU1-0] 151.041969 s: Get Full Buf Cb = 122.7 fps
[IPU1-0] 151.042060 s: Put Empty Buf Cb = 122.7 fps
[IPU1-0] 151.042121 s: Driver/Notify Cb = 142.81 fps

Thanks,

Hi,

Get Full Buf Cb = 122.7 fps (Number of times 'getFullBuf' callback was called by next link)
Put Empty Buf Cb = 122.7 fps (Number of times 'putEmptyBuf' callback was called by next link)
Driver/Notify Cb = 142.81 fps (
Number of times 'notify' callback was called by a link Notify could mean one of the following
display ISR for display link or
Capture ISR for capture link or
IPC Notify ISR for IPC link)

So it's calculated depends on number & elapsed time.

Thanks

Hi Gaviraju,

Does that mean Next Link is too slow in responding to the Driverr/Notify Cb and it's falling behind?

Thanks,

True when the frame dropping occurs in the ISS Capture link otherwise it's working well.

Thanks
