Tool/software:
I'm having trouble with GStreamer when trying to display my 60fps camera video to screen. I set up a pipeline like this:
v4l2src → tiovxisp → sink(kmssink or fakesink)
Then I tried using both fakesink and kmssink as the sink. I attached the same probe to their sink pads to measure latency—checking the buffer's PTS vs. the current time.
With fakesink, everything runs smoothly at 60 fps with low latency. But when I switch to kmssink, the latency jumps to 150 ms, and the frame rate drops to 30 fps—even though both sinks have sync=false.
Any idea why kmssink is causing such a big slowdown?
Here is the info of fakesink piepline
> This sink probe measures the time difference (in milliseconds) between consecutive callback invocations, which helps estimate the actual frame rate.
