Thumbnails missing

[suknil]

Hello,

I'm running v1.36.8 on an Intel Core 2 Duo with 6 cams @5 fps. Everything is fine so far. However, I have a problem with thumbnails in the web view and on ZMNinja. I never had this with v.1.34.

This is a typical entry in the log:

Code: Select all

Can't create frame images from video for this event 185255-video.mp4Command was: -ss 12.59 -i /var/cache/zoneminder/events/2/2021-10-09/185255/185255-video.mp4 -frames:v 1 /var/cache/zoneminder/events/2/2021-10-09/185255/00062-capture.jpg 2>&1Output was: sh: 1: -ss: not found

This happens from time to time. What can I do to solve this?

Thanks for your support. And thanks to the developers for this great software.

Kind regards,
suknil

I can't tell you how to solve it, but the error is caused by an incomplete command line - It should be:

ffmpeg -ss 12.59 -i /var/cache/zoneminder/events/2/2021-10-09/185255/185255-video.mp4 -frames:v 1 /var/cache/zoneminder/events/2/2021-10-09/185255/00062-capture.jpg 2>&1

At a guess, I'd say that perhaps some ZM system variable pointing to ffmpeg isn't set.

Hi kitkat,

Thanks for your input. I see what you mean. And I don't understand why it only happens once in a while.

There is another entry in the log that occurs quite often:

Code: Select all

Got no frame. returning nothing

You got me at a loss.

Kind regards,
