No clip available for event

Describe the bug For my MJPEG esp32 cameras I see around half of the events having no clip available. Looking into the logs, I consistently see this error:

2021-07-14T15:44:37.224138051Z frigate.events                 WARNING : Unable to create clip for bi
rdbath and event 1626277440.949275-icwlxf. There were no cache files for this event.

The event time is 8:44:00, the error was logged 37 seconds later.

I ran the following in another window (using docker exec): while true; do date; ls -ls bird*; df -h .; sleep 2; done and the output around the event time is:

In the camera config I have pre_capture: 2, so it seems to me that the 20210714084321.mp4 should work for that. I also have post_capture: 5 and the 20210714084403.mp4 recording should work for that (it’s actually still being written to by the time of the error, I can see the file increase in size in subsequent ls outputs).

This does look to me like it’s neither an ffmpeg issue nor a disk full issue. I’ll see whether I can add some info to the error message to print out what it expects.

NB: there seem to be a number of related issues, for example: #932 #896 #1096
