Hi,
First of all, thank you for buying the book! It would be helpful if you could elaborate on it’s not so useful when running Digicam on Windows. Are there any specific topics you’d like to see covered?
Regarding your question about PIwigo video uploads. Can you upload a video directly from your machine to Piwigo? If you can’t then the problem most likely lies with Piwigo. If you can, then it might be a digiKam issue. In that case it would make sense to post your question to the digikam-users mailing list.
Kind regards,
Dmitri
