Something very similar to this is being discussed in https://trac.ffmpeg.org/ticket/8366 > 3. If support is still in the future, would you be open to me > contributing a patch that implements it? Yes please I think opening a generic ticket for this would be a good move. Having the ability to trim essence would be very useful.
