I have tryed ffmpeg -i video.avi image%d.png but there is a problem ffmpeg: symbol lookup error: ffmpeg: undefined symbol: sws_getContext

Did you download a ffmpeg binary or compiled it yourself? I tried a google for that error and found : FFmpeg showing sws_getContext error If you find following error while running ffmpeg in the server, you need to compile ffmpeg from the source by enabling swscaler using --enable-swscaler option. The steps are given below Error:- #ffmpeg ERROR: ffmpeg: symbol lookup error: ffmpeg: undefined symbol: sws_getContext svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg ./configure --enable-mp3lame --enable-libogg --enable-vorbis --enable-shared --enable-swscaler --enable-gpl http://kb.bobcares.com/?View=entry&EntryID=429

Avidemux File > Save > Save Selection as JPEG images... Can save individual frames as jpg or bmp. Can always convert jpeg back to png with ImageMagik. It's an option.
