Generating Thumbnails from FLV using FFMPEG
I had to make some modifications to a zenGallery system which was going to hold a lot of flash video files and I was too lazy to create a thumbnail for each image so for awhile it had the default thumbnail.
After a few, “what’s with the thumbnails?” I decided to write a script that executed ffmpeg to create a thumbnail for each video (from the frame 10 seconds into the video) and write out a jpg image.
The filename currently just replaces .flv with .jpg and my settings for the call are pretty generic. If anyone has questions about this feel free to ask.
Grab the .phps file from here: Generate Thumbnails from FLV files using FFMPEG

It appears that it parses through a directory and creates thumb nails for any images in that directory. It doesn’t appear to be the type of script you call in the middle of another but that you run after you upload new photos. You can, however, reverse engineer it to make your own script to use inline. Something like if file_exists($filename) then display image, else ffmpeg the flv named xx and generate the new image.
Yeah, that’s not really a clear explanation, but basically it wouldn’t take much effort to reverse engineer it and read some documentation to make your own
Nice script, btw.

Thank you for this. That´s what I´m workin on for days.
When I test it on my local Server, everything is fine.
But I´m building an application for recording the webcam-Stream of the user on an external Wowza-Streaming-Server. The Streams are stored in a directory on that Server. I need now to make Thumbnails out of these stored FLV-Clips, which are available on my PHP-Webserver.Does someone have an Idea?

Hi, This is exactly what I was trying to figure out!
I dumped a precompiled copy of ffmpeg on my server, chmod +x to make an executable, and I tested that is working.
However I have never come accross a phps file, and was wondering just what I do to execute the script?
Thanks!
