TypeError - Files when parsed by MediaInfo returning as 'NoneType'

[d-elv]

Hi there,

First of all I'd like to say what a fantastic package/module/library this is. It's perfect for what I'm trying to achieve!

Unfortunately except for the above snag. When trying to parse certain files I get the below error, claiming that what it's parsed is 'NoneType'. I've done some tests with a few different files, and the only obvious thing I'm seeing is that it relates to the Writing library, all of the files that have issues have the Writing library attribute 'Apple Quicktime'. I was able to get this information via using MediaInfo normally. (Version 20.09)

I suspect these are files made using Adobe Media Encoder, and it could just well be that this isn't in libmediainfo library? Either way, confirmation if that is problem would be greatly appreciated.

I'm running this on an iMac, looking to test on a Windows machine soon.

Here is the error, and some information on the files I scanned, ones that did have errors and ones that didn't.
I have changed the filenames due to sensitivity of the content, rest assured there are no illegal characters in any of the filenames.

THE ERROR

media_info = MediaInfo.parse(input_file)

Hi, are you using v5.0.3? It looks a lot like the issue I fixed yesterday for #100.

[d-elv]

Yep you're absolutely right, I'd re-installed the package a couple of times yesterday evening when troubleshooting but I guess 5.0.3 hadn't rolled out by then. I'm now up to 5.0.3 and it works like a dream.

Thank you and apologies for repeating a problem! I thought I'd looked for a similar issue but apparently not!
