I'm looking for a .NET library or command line tool that would allow me to extract thumbnails from FLV files (AVI would be nice too, but not required). Something that would allow me to extract a frame maybe 15% into the movie would suffice. If it could extract a few frames, let's say one frame per minute, and make an animated GIF out of those frames it would be even cooler. Doesn't have to be open source, but it has to be something I can incorporate into my application.
Thanks.
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.
original title: Most . mp4 files have a thumbnail. Yet, some, newer files, do not.
Ffmpeg.
ffmpeg.exe -i video.flv -an -ss 00:00:03 -an -r 1 -vframes 1 -y %d.jpg
(Save a single frame at position 3 seconds during the video as a jpeg)
