The following command line extracts the I frames from the video ffmpeg -i input.flv -f image2 -vf "select='eq(pict_type,PICT_TYPE_I)'" -vsync vfr thumb%04d.png
But the frames are sequentially numbered ..like thumb0001,2,3,4,5.... Suppose the 9th frame is an I frame then I want the the extracted frame's file name as 'thumb9.png'...suppose if 18th frame is the next I frame then the extracted frame's filename should be 'thumb18.png' or '18.png'... How to achieve this?
