Hello everyone,

I'm having an issue using Video module on IIS 6, on a content type , it's intended to create thumbnails out of uploaded video file using ffmpeg.exe ,
on my log entry, I get :

"error generating thumbnail for video: generated file sites/default/files/video_thumbs/310/video-thumb-for-310-5.png does not exist.
Command Executed:
c:\site\ffmpeg\ffmpeg.exe -i "sites/default/files/video_tv/video.flv" -an -y -f mjpeg -ss 0 -vframes 1 sites/default/files/video_thumbs/310/video-thumb-for-310-5.png
Command Output:

I haven't used this application before so I stronly encourage you to review the articles below before deploying this solution into a production environment.

You may be able to allow write access to IUSR to the /video_tv/ directory only for this to work. If it doesn't work then you may need to create a separate account that has ffmpeg execute permissions and write permissions for that directory only with normal read/script execute permissions for the rest of your site.

Here's a couple of articles that may be of some help.

Or you can start here to scroll through all of the security docs for IIS 6. Probably a good idea given what you're looking to do here. http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/I...

Hope that helps.
