Hi Shane,
Thanks for the advice, I managed to get the kernel Image recompiled. just checked, the nbuffers is 2. According to this topic (Vi_capture_status function take about one-frame time latency), buffer number of 2 seems already the optimal setting… I guess if I further reduce it to 1, it will drop frames.
Can I check with you which part configures and determines this buffer number? Is it dynamically determined?
Best,
Wenhai.
