overlaying togglable annotations with mencoder
Hello! I'm trying to create a video with an overlay containing annotations (e.g. arrows), that can be toggled on/off with common players. It seems bmovl allows to combine two videos, but is specific to mplayer/mencoder. If used with mencoder, the annotation (video) gets hard-coded and cannot be toggled any more. Promising but also specific is SVG overlay: http://mplayerhq.hu/pipermail/mplayer-dev-eng/2006-August/045364.html The only other idea I have is to (mis-) use an mpeg2 subtitle stream (dvdsub). However, the only program I could find to create such a stream from my annotation images is spumux. spumux on the other hand only allows bilevel+alpha images. I'm not sure if that is simply a spumux limitation or a limitation for dvdsub streams. Does mencoder or other tools offer other possibilities with less limitations on color and size (e.g. 16 colors, HD)? Many thanks for any suggestions Roman

I believe you can overlay almost anything textual using Advanced SSA (ASS) subtitle format, which you can (but don't have to) mux into a common container with the video without re-encoding it, for example using ffmpeg or mkvtoolnix.
