问题
I have to make thumbnails from banners in swf file format (flash 9). I want to use php, but if that's not possible anything which work in a linux command line is fine by me.
I tried to open them with ffmpeg-php, but it says: Can't open movie file /where/the/file/is
The file is there and is readable by the user.
Any ideas?
