ffmpegthumbnailer ([login to view URL]) is a open source wrapper to ffmpeg written in c++. With ffmpegthumbnailer you can create screenshots of a given movie via command line. Unfortunately there is a bug that has not been fixed yet: [login to view URL] On anamorphic videos you would use something like this, to create a screenshot of the source-movie with the correct aspect ratio: $ ffmpegthumbnailer -s 0 -i [login to view URL] -o [login to view URL] Now the problem is, even though the aspect ratio is correct, the dimensions are wrong (e.g. to small), which means the [login to view URL] is getting resized, thus losing video information. If you open the uploaded "[login to view URL]" with VLC it will correctly autoresize the window to 1011x568 - which are the correct dimensions + aspect ratio. If you use ffmpegthumbnailer to generate a screenshot, you will get a 712×400 which still has the correct aspectratio, but is smaller. I am searching for someone who knows c++ and can modify the parts so it will work correctly. If you know your way arround ffmpeg it is of course a plus and you will be able to quickly fix it. All the information (SAR/DAR/PAR, width/height) should be retrieved directly via the libraries. The bug must be fixed nicely, no "exec commandline wrap arounds" please. Thank you!

Hi, That's not really a bug, because the thumbnail is supposed to be smaller than the original picture (it's called thumbnail afterall ..) Anyway, I know how to do it. And not really many lines will have to be added to achieve that. So to be sure , please do confirm that i did understand you correctly : you cant the thumbnail to be the same size, same aspect-ratio as the original video. If you agree i can start this today, and deliver it less than 24hours working perfectly. Of course you only pay upon job completion (I work in set-top box firmware department of STMicroelectronics, so what you want to achieve is a very common task for me ..) Contact me back if interested. Cheers
