Hi,

Video generation '/usr/bin/zmvideo.pl -e 45113 -r 1 -s 0 -f mp4' failed with status: 9

Hi,
I forgot to say which version is FFmpeg, it is version 4.4.2
any idea what to do?
thanks

Try running it on the command line, perhaps there will be better output.
sudo /usr/bin/zmvideo.pl -e 45113 -r 1 -s 0 -f mp4

here the error
31/10/2023 21:37:12.814967 zmvideo[329671].INF [ZoneMinder::Event:302] [Creating video file Event-45113-r1-s1.mp4 for event 45113]
Use of uninitialized value in division (/) at /usr/share/perl5/ZoneMinder/Event.pm line 304.
Illegal division by zero at /usr/share/perl5/ZoneMinder/Event.pm line 304.

here the 304 line of the file
my $frame_rate = sprintf('%.2f', $self->{Frames}/$self->{FullLength});

my understanding is that $self is 0 so the division is not valid?

can someone check that line?

thanks

I don't know how old you zmvideo.pl is... but current 1.36.33 has no line 304. I don't know if our current version works as not many people use it, but it's a good place to start.

Illegal division by zero at /usr/share/perl5/ZoneMinder/Event.pm line 304.

I suspect $self isn't zero, but the member {FullLength} is zero. It warns about something be un-initialised, which would be my first instinct to check. Uninitialised things often, but not always, end up at zero until set otherwise

ok I have searched in the hard disk that event
there are files
then I looked at the event and I fount that file with a name like 0000capture is missing and so only one frame is present
in the directory there are like 15 frames (jpg files)
so I think I can just delete this event and live without problems also because only a shadow is visible in that event

probably an error in the file system has not saved the 0000capture file ?

thanks everyone for the attention
regards
Andrew

There should not exist a 0000. File. Counting begins at 1
