Hello,

Hi Eridan,

sorry to hear you're running into a challenge there.
Somehow your example went lost or did not get posted? I'm not seeing the examples.
Note: it takes a few posts before the forum allows posting images or attachments.

As for the FourCC application; the development has been stopped several years ago.
What exactly are you trying to accomplish? Maybe I can help ...

Hi Hans,

Let me try to explain with more details..
I have NAS server with about 9000+ video files in a complex directory structure, where both files and directories may have special characters.

Approximately 4000 of these videos have old FourCC strings = DIV3, DIVX, DX50, XVID (upper or lowercase), so they cannot be played on some modern TVs. I want to change that by using FourCC-fix to modify the codec string to alternative codec, DIVX/FMP4; XVID/FMP4; DX50/FMP4; DIV3/MP43.

I have complete listing of all files with their FourCC codes (in CSV format) so I know which files have old FourCC and to what should it be changed, but I haven't found any way how to "feed" this listing to FourCC-fix application.

So I tried approach to insert the entire directory structure with movies to FourCC-fix application window and then let it change codecs one by one. This approach worked fine for about 50% of files. The other 50% got rejected with error, because the FourCC-fix didn't load their path or file names with proper special characters.

As an example I've created following directory structure:

test\ježek\špatné_jméno.avi

If I insert just the avi file "špatné_jméno.avi" to FourCC-fix window, it works fine. Proper name is displayed and can be processed (codec name changed)
If I insert directory "ježek" to FourCC-fix window, nothing happens. I think that here the FourCC-fix has problem to access the directory with special character and read it's content.
If I insert directory "test" to FourCC-fix window, the FourCC-fix will find the video file, but it will be loaded with question marks instead of special characters .. like this: "test\je?ek\?patn?_jm?no.avi". Consecutive attempt to change codec fails with error

I'm attaching links to picture1 which is case 1 (OK) and picture2 which is case 3 (KO) with the error message.
Case 2 is difficult to demonstrate as the FourCC-fix doesn't return any error, it just doesn't import anything.

Please let me know if this explanation helps or if you have more questions..

For future reference, I've added the pictures here:

I'll go look in the code to see if there is an easy fix.

Note: as for "feeding" info the the application goes - unfortunately, this application was never designed to take any command-line parameters. 😞 

Before I can proceed trying to see if I can find a quick fix can you let me know what platform are you working on?
Since Windows is the most notorious one for having issues with special characters, I presume you're using Windows?

Well, I work primarily on Windows and NAS is running on armv71 customized Linux, without GUI, so I can't run FourCC-fix on it.

But I have some Linux VMs with GUI in Hyper-V, so I could try to run FourCC-fix on them. I just need to figure out how to connect to NAS from them, as they are in different networks. I'll update later today if it will help or not.

Hello,

FourCC-fix in Linux GUI worked, it processed all files with special characters properly.

Thank you very much! :)

Awesome! Still too bad it doesn't work entirely OK under Windows, but at least you're helped for now 😊 

Thanks for confirming! 👍
