![]() The - for both commands specifies that a pipe will be used for output and input respectively. The -f image2pipe tells ffmpeg to split the video into images and make it suitable to be piped out, and -vcodec ppm specifies the output format to be ppm (for some reason if the format is png, either convert does not read all the images from the pipe, or ffmpeg does not output them all). If you would prefer to avoid intermediate image files, the commands provided by LordNeckBeard can be piped between ffmpeg and ImageMagick’s convert so that no intermediate files are required: ffmpeg -i input.flv -vf scale=320:-1 -r 10 -f image2pipe -vcodec ppm - | convert -delay 10 -loop 0 - output.gif ![]()
