i'm using ffmpeg for extracting a video frame from which i want to create a thumbnail using php thumb. creating the video frame works, but when trying to save the thumbnail file (under a different name - same directory) i'm getting this error:
PHP Fatal error: Uncaught exception 'RuntimeException' with message 'File is not writeable, and could not correct permissions: d:/Webs/bla.jpg' in D:\Webs\phpThumb\lib\GdThumb.inc.php:656
it can't be a permission problem as i can already store the videoframe into the same folder.
any ideas what could be wrong?
