What is the minimum latency time that i can get for moving camera raw video from CSI to PCIe ?

hello MGRRGB,

may i know what’s your purpose?
could you share more details about why you’ll need PCIe to handle raw files.
thanks

Hi
application : Home Automation, i am using the TX2 for Frame Grabber and preprocessing , the video analytics will be executed on another board the connection is through PCIe

hello MGRRGB,

there’s v4l2 standard APIs from CSI to memory.
you could add debug messages to evaluate the latency between below functions,

CSI->VI->MEM
csi4_start_streaming()
tegra_channel_capture_frame()
vb2_buffer_done()

about the MEM->PCIe, it should be standard also. please update the topic if you meet any issues.
thanks
