Change metadata extracting behavior

Hi.

I've added many homemade videos to the library recently.

The file names start with dsc_ and obviously don't have any metadata and do not appear in any database.

Unfortunately for me, the extractor tries to guess what the metadata is and sticks awkward movie names
("The butcher") with strange thumbnails.

Can you please change it so when the filename is not in proper format or no metadata is found
serviio would just add a thumbnail and leave the original file name?

Thank you!

Move your files to a separate shared folder and disable retrieving metadata for it in the console.

Thanks,

I did that, but for some reason it still extracts metadata for directories without metadata checked for them.
I even uninstalled and re-installed Serviio but problem persists.
