Windows Live Photo Gallery and 3rd party jgeg codecs?

Postby Samizdat on Sun Jul 03, 2011 6:55 am

I am interested in buying your codec pack (for use with Windows 7 Pro) but I also plan to install Windows Live Photo Gallery (primarily because I understand it is a requirement for installing Windows Live Movie Maker.) I have read that there was an issue with WLPG silently recompressing jpegs when a 3rd-party jpeg codec is installed, as you explained here:

Can you tell me if this is still an issue? I don't want to use WLPG to automatically tag any of my photos in the first place, and certainly don't want it recompressing jpegs in the background. Do I need to disable/remove the jpeg codec to be safe? I want the codec pack primarily to view Nikon's NEF files.

Thanks.

As far as we understand, Photo Gallery now disables metadata editing when a 3rd party JPEG codec is installed. This is a bit crude, but it works around the issue. That said, every component in the FastPictureViewer Codec Pack is optional: you can opt-out the JPEG auto-rotation feature easily during setup, but you'll lose JPEG auto-rotation in Windows Explorer, Media Center 6.1 and of course Photo Gallery.

Thanks, Axel; that is good to know! I will probably opt out of auto-rotation as you describe, just to play safe. At the risk of sounding dense, I'm not sure what I'd gain by opting to use it anyway. I typically use Nikon's ViewNX to import my photos (RAW or jpeg) and it seems to rotate them all properly from the start.

Auto-rotation for JPEG is a sorely missing feature in Windows. Most raw codecs in the FastPictureViewer Codec Pack perform automatic rotation of the files they handle and our JPEG auto-rotator does the same for .jpg files.

The only negative side effect is that JPEG metadata editing is currently disabled in one application (for a lack of a better solution). You can still rate and tag JPEGs normally from Windows Explorer while our auto-rotating JPEG codec installed, it disables itself at the appropriate time and the stock JPEG codec gets used instead.

Again, if it bothers you the slightest, just opt-it out during setup! The raw support and the many other formats supported by the Codec Pack are entirely unaffected as this component is optional 8-)
