In the following XML between the tags there are some Chinese chars. SimpleXML doesn't seem to like those and crashes the process.

  Please use the argument -v to see more details.

@Fossil01 Thanks for reporting this issue. An old pull request consider removing utf8_encode to solve a "bug".
Could you try to remove this call and see if that solve the problem ? If not I will try to fix this issue this weekend.

@mhor nope same thing happens if I remove those 3 lines.

[mhor]

Thanks for your quick answer, so it's definitively related to xml string returned by mediainfo.
This is looking as an acceptable solution for me, I will try to implement this as soon as possible but if you want feel free to open a pull request with your solution I will be happy to review it.

I'll have a crack at it after Christmas. Cheers.

[mhor]

@Fossil01 did you have test the fix I've done (PR #93) ?

Completely forgot about this. It seems to work now.

Looks like I am still having this issue.

Maybe we can use a function like this to strip out invalid chars:
https://stackoverflow.com/a/3466049

Aha. It looks like aca1198 never made it into the master branch and thus in a release.

When I add these lines it seems to fix the issue too:

$xmlString = preg_replace(
    '/[\x00-\x08\x0B\x0C\x0E-\x1F]|\xED[\xA0-\xBF].|\xEF\xBF[\xBE\xBF]/',
    "\xEF\xBF\xBD",
    $xmlString
);

XML it fails on currently:
