End of recording causes temporary freeze #693

Closed Andres9713 closed 6 months ago

Andres9713 commented 6 months ago

Hi, I am using the latest RPI_Cam_Interface on a few different Raspberry Pi Zero 2W's, running on bullseye. My issue is that whenever a video recording is stopped, either manually or due to reaching a 'video split' interval, the preview window freezes for a few seconds (maybe 10 seconds) before becoming responsive again. The issue is that in 'Video Split' mode, the Pi simply stops recording after the freeze (once the preview starts the 'record video' button goes back to blue). Notably, this freezing issue happens even when 'boxing mode' is off and the length of the freeze does not appear to be related to the length of the recording prior to the end of the recording.

The .h264 files are written to the local SD. I am not using motion detection, and the motion detect mode is set to 'monitor'.

The last few lines of the log (/var/www/scheduleLog.txt) around one of these freezes/failures to continue recording after split read:

Thank you for any input on this.

After more searching, I found the following post on the forum: https://forums.raspberrypi.com/viewtopic.php?t=63276&start=4100#p1166424 which suggested adding a 2000 ms second Buffer. This solved both of my issues (the freezes at the end of video recordings, and the resulting inability to use Video Split). So, I'm closing this issue.
