I see what you mean. I have not given much thought to the question, I do not
know what it would require to implement it. If you already have some ideas
about it, please let me know.

My intuition is that it would use some kind of command passing from in the
output->input direction. The work I am doing in this series and the next
ones is about the input->output direction, I believe it is quite orthogonal,
except possibly to ensure correct synchronization between the directions
(i.e. knowing if a frame that arrives on output belongs before or after the
seek). Anyway, I will keep in mind and try not to write anything that would
make implementing seeking harder than it already is.

Regards,
