Make each <value> I-frame an IDR-frame (default: 2).
In H.264, I-frames do not necessarily bound a closed GOP because it is
allowable for a P-frame to be predicted from more frames than just the one
frame before it (also see frameref).
Therefore, I-frames are not necessarily seekable.
IDR-Frames restrict subsequent P-frames from referring to any frame
prior to the IDR-Frame.
