It depends on how much complex your application is, and how much
coding/scripting you're willing to do.

Image->video can be done through the image2 demuxer, for text
overlaying you can either use the ass filter or drawtext. You can
generate events and send them to the filtergraph, e.g. for changing
the parameters used by drawtext on the fly depending on timestamps, but
this feature is underdocumented.
