Hello, I try to find the exact place where frame are captured in kernel. I rather find the first place, but if that is a problem, I will use another method you are familiar with. I use tegra tx1 with mipi camera of a development kit, so I tried to add some printing in kernel in vi2_fops.c in tegra_channel_capture_done() and tegra_channel_capture_frame(), but nothing is printed while the userspace application capture frames (using gstreamer). Although there are no print during frame captured, yet, there are printed logs in vi2_channel_stop_streaming, vi2_channel_start_streaming. Is there any reason why I can't see any logs ? Is the rate is too high ? Should I try to find where it is captured in v4l2 framework in kernel instead ? Thanks, ranran
