-/*
- * filter to output only 1 every n frame, or only the I (key)frame
- *
- * The parameters are:
- *
- *    [I] | [i]num
- *
- * if you call the filter with I (uppercase) as the parameter
- *    ... -vf framestep=I ...
- * then ONLY the keyframes are outputted.
- * For DVD it means, generally, one every 15 frames (IBBPBBPBBPBBPBB), for avi it means
- * every scene change or every keyint value (see -lavcopts).
- *
- * if you call the filter with the i (lowercase)
- *    ... -vf framestep=i ...
- * then a I! followed by a cr is printed when a key frame (eg Intra frame) is
- * found, leaving the current line of mplayer/mencoder, where you got the
- * time, in seconds, and frame of the key. Use this information to split the
- * AVI.
- *
- * After the i or alone you can put a positive number and only one frame every
- * x (the number you set) is passed on the filter chain, limiting the output
- * of the frame.
- *
- * Example
- *    ... -vf framestep=i20 ...
- * Dump one every 20 frames, printing on the console when a I-Frame is encounter.
- *
- *    ... -vf framestep=25
- * Dump one every 25 frames.
- *
- * If you call the filter without parameter it does nothing (except using memory
- * and resource of your system,. of course).
- *
- * This filter doesn' t work like the option -sstep seconds.
- *
- * The -sstep seek to the new position, without decoding all frames but,
- * expecially on avi file coded whith mpeg4 (lavc or xvid or divx), the
- * seek is not always too much precise.
- *
- * This filter simply discard the unwanted frames, so you are very precise in
- * counting the frame but sometime you use a lot of CPU for nothing.
- *
- * As usual it depends on what you're doing.
