Lost frames, 50 sec section length, & zm.ffmpeg.cpp error

I am currently running 1.33.9~20190612100557-xenial

I have a cron job that changes the runstate using: /usr/bin/zmpkg.pl "New State"

This morning upon the change of state my continuous events were all reduced to approximately 50 seconds length, with a ten second loss between events, and the above error being generated in the log.

I tried to restart the state through the console interface; the problem continued. I rebooted the machine; the problem continued.

Finally, I used the console interface to change to a different state, and the events were created with the section length specified in the settings, events had a slight frame overlap at beginning and end, and the error messages stopped. I then used the console to change back to the state that had been specified by the cron job when things stopped working properly, and everything seems to be working as expected in that state also . . .

I don't understand how the problem could persist through the reapplication of the state, a reboot, and then go away with a change to a different state?


*** On further investigation, I see that after the cron job runs, I am getting this broken behaviour for an hour. However, after this hour, the sections begin and end properly again. What am I doing wrong?


Thanks,

Alec

Do you have values set in MaxFPS and AlarmMaxFPS in your monitors? If so, clear them.

Thanks for responding so quickly Isaac. However, those fields are already clear. Is there anything else obvious or other information that I can provide that would be helpful?
