Hi Joan

The customer could get vProfiler log currently, but only got log file while playback media file from storage device(like SD card or USB), the customer want to know how to config can get MIPI CSI vProfiler log file.

Thanks.

do you mean vpd file? if yes, this is created by vProfiler, your cutomer couldn't creat it?

Hi Joan

Yes, I mean is vpd file, the customer can generate vpd file when playback video stream, but use MIPI CSI capture image can not generate vpd file.

Thanks.

Hi Felix,

The profiler picks GPU usage statistics. When you tested with video playback I assume you might use a G2D-based element or used the GPU somehow for display. I am not aware of how is your customer capturing or how is the pipeline (if it is GStreamer), but if the GPU is not in use I would expect no profiling data is acquired.
