There are exactly three acceptable behaviours for request_frame() and all the functions it calls: * it pushes a frame and returns 0; * it issues a ff_request_frame() on the input and returns 0; * it returns EOF or an error. If the "few times" correspond to frames pushed, then it is ok. Otherwise, it is not. lavfi will not activate filters saying "hey, you told me last time you had nothing to do, but just in case I am taking news". A filter should never do nothing.
