Help with smart record issue - minor pause in most recorded files

Sure. It is only for deepstream-test5.

@Fiona.Chen - I have found a way to stop these pauses occurring. I am using Hikvision brand cameras and allegedly they are known to be jittery. So I started playing around with the camera settings and have found that if I make the i-frame interval double (or at least a lot more) than the fps the weird pauses go away and I haven’t seen one after two full days worth of recording (via smart record events in my deepstream pipeline).

Can we discuss why that would be so?

Increase the jitterbuffer latency made no difference - even up to 5 seconds. I have left it at 1000ms now. Deepstream-test5 seems to default to 100msec but that seems very low.

Setting the drop-on-latency property of rtspsrc seem to make no difference at all either.

At no time would I see any warnings or errors from the gstreamer debug logs about frame drop.

@Fiona.Chen wondering if you can comment on this thread and my last post where changing the I-frame interval stops the smart record “pause” issues…?

@jasonpgf2a Seems we can not reproduce the problem with our rtsp cameras. Is there any method to share your camera stream to us for testing?

See my last couple of responses. There is no need for you to reproduce the error - I was just wondering if you have any thoughts as to why increasing the o-frame interval at the cameras could affect it??

It is hard to explain it. When we see pause, there must be some timestamp problem or some frames are missing. I don’t know how intra frame impacts the timestamp.
