imx8: gstreamer mjpeg stream from camera displays only each third frame.

Question asked by Ondrej Bilka on Mar 7, 2018

When I play mjpeg stream from camera fps is 8.34, no dropped frames and stays at that value no matter what I do. If I launch ten such streams in parallel fps decreases bit to 7-8, so this looks unrelated to performance.


Edit: I found out by setting camera fps to 5 that result has fps 1.66 and initial fps was 25. Both actual fps are 1/3 of original so it looks that it displays only each third frame.


Following pipeline shows what properties I tried, as well as trying to add queues, situation is same when I remove those.
