"System.FormatException: The input string format is incorrect"

[TheWonderfulTartiflette]

Using 2.1.3, I'm getting this error. I've linked the screenshot of it (parts of it are in French)

Both files are in .mp4, the source is in H264 and the compressed one is in AV1

I have exactly the same error with 2 .mkv files in H264. My Windows is also in French, maybe that's something to do with that?

The problem seems to be with the part where I'm reading the xml file generated by vmaf to show the results. Could you share a copy of an xml file generated by vmaf-gui? If I remember correctly they should be getting generated in the root directory of the executable

[toutrob]

Yes sure.

One more question, what's the absolute path to that xml file on your drive?

[toutrob]

C:\Users\robin\Downloads\vmaf-gui.2.1.3\Release

[ThatNerdUKnow]

Strange, I wouldn't think that path would cause a format exception. I'll need to investigate what can cause Xdocument.Load to throw a formatexception

[ThatNerdUKnow]

If I force vmaf-gui to skip all processing and load the XML @toutrob provided, it seems to load just fine. That could possibly rule out the formatting of the XML document. I do also wonder if this is a character encoding thing, perhaps the behavior of XDocument.load depends on the locale of the system?

[ThatNerdUKnow]

Okay, I think I've got it. Apparently the french locale uses commas instead of periods to represent decimal points. It looks like I should be able to override the locale that XDocument is using to load the xml file, so I'm going to give that a try.

@toutrob , can you please try using this release?

It works perfectly for me, thank you for your work!
