All recorded videos have a 3 seconds freeze in the beginning

[hpicelli]

Hi there,
I'm facing this problem.
In a recorded video (all videos have this issue), it plays one second, freeze for 3 seconds, then plays normal until the end.
I'm using mp4 (h264) now, but tested avi (mpeg4) and the problem persists on all formats i've tested.
Check attached video.

motionEye Version: 0.43.0
Motion Version: 4.5.1
OS Version: Linux 6.1.0-13-686-pae (Debian 12 32bit)
*Using 32bit OS because i'ts a old machine. This issue is only on 0.43.0, 0.42 runs ok.

Best regards,
Henrique

I have the same problem where first 3 seconds of every recorded video is frozen. Running on Raspberry Pi 5 with 64-bit OS.

I have the same problem. I thought it was the encoder using too much cpu but changing the codec makes no difference

I also have the same problem. Is it possible to downgrade to version 0.42.1 under dietpi?

[hpicelli]

I think that is a issue on 0.43. I'll reinstall using 0.42. This is really annoying.

Maybe this has something to do with the pre_capture value:
https://motion-project.github.io/4.5.1/motion_config.html#pre_capture

Can someone who is experiencing this issue set the 'Captured Before' in motionEye to 0 and see if it makes a difference?

[MichaIng]

Indeed, pre_capture is set to 1 (second) by default. Not sure whether it can take 3 seconds to process this 1 second though. At least worth an attempt. Can be changed in motionEye UI.

EDIT: Also strange, while there should be 1 second of still frames at the beginning of the recording, it is not. Or the number of changed frames of the 1st second is not above the threshold, and would be missing without pre_capture 🤔.

[hpicelli]

The "captured before" and the "captured after" are defined in frames, not seconds. Any tip? Here "motion gap" is defined to 5 seconds, "Captured Before" and "Captured After" are defined to 10 frames, and the "Minimum Motion Frames" are defined to 10 frames. See attached image. Best regards.

@hpicelli

What type of camera did you use?
Did you upgrade motioneye to 0.43.0 from 0.42 or a fresh installation?

[MichaIng]

The "captured before" and the "captured after" are defined in frames, not
seconds.

Oh right. Please assign "0" to "captured before", to see if it plays a role at all. "captured after" and "motion gap" do not matter in this regards.

See attached image.

Even if you have set pre_capture=0 there is probably still a buffer:
https://motion-project.github.io/4.5.1/motion_config.html#minimum_motion_frames
But even if this were the problem, it would be more down to motion 🤔

[MichaIng]

But that section of the docs at least does not state that one will miss frames until the buffer has been processed. I am not sure how motion handles this internally, so worth a try to disable pre-capture, where this is mentioned explicitly. But if it does not help, also setting minimum motion frames to "1" could be tested. motionEye sets this to 20 by default, but can be adjusted in web UI as well.
