Follow-up Comment #1:

The global 'error_state' variable has been useless for quite some time now. 
It's been removed on the default branch (what will become version 8.1 in about
a year).  Since about 6 years ago, it has never had a value other than 0 in
Octave code and is no longer useful for checking whether an error has occurred
because exceptions are thrown, so checking the state of a variable after an
error occurs is not useful except inside a 'catch' clause that handles
'octave::execution_exception'.

All uses of this variable should be removed from the video package and any
other packages that still use it.  You should have been seeing a warning at
compile time about it being deprecated since before version 6 was released (it
was marked as deprecated in May 2019).
