How can I generate thumbnail previews for FLV files in Windows 7?

Solution 1:

A much cleaner way to get thumbnails for FLV (as well as MKV and OGV) videos in Windows Explorer is to use the program Icaros. It is made by the person who makes the Shark 007 codec pack, but you don't need to install the codec pack for Icaros to display thumbnails because it includes a built-in decoder.

_{(Personally, I am really opposed to super-ultra-mega-hyper-codec-packs. I do not like (nor recommend) installing big packages like these because you never really know what they are doing to your system. Even if it is not malware, they usually add clutter and perform modifications that may not be necessary—they tend to be either scripts that automate installing all of the individual components or manual hacks of the main parts of the individual components.)}

Solution 2:

Well, this is a long way, but if you install K-Lite Codec pack, it asks for which file types thumnails need to be generated for explorer. It's a long way but it works.
