Fails without errors after upgrading from PHP 7.3 to PHP 8.2

[JungleGenius]

First thank you for posting this with the generous licensing terms. That said I just recently updated to PHP 8.2 and it quit working, but does not throw any errors either. Normally the exec_output array looks like this:

( 
    [0] => ** Imported 1 metadata tags
    [1] => Parsed 1551 MPEG TS frames with 0 errors
    [2] => Total of 1 programs and 2 streams
    [3] => Injected 0 frames
    [4] => Finished in 4.734ms
)

But now it only outputs:

( 
    [0] => ** Imported 1 metadata tags
)

I'll be happy to offer a modest bounty to get this working again under PHP 8.2. There is so much low level bit twiddling going on in the code I don't feel like doing this myself unless I absolutely have too. If it comes to that I will make a pull request.

Thanks.
