When we receive a video or audio buffer, we calculate the next stream time based on the current stream time + buffer duration. If the next buffer's stream time is after that, we issue a warning. This happens because the stream time incoming from Decklink should be really constant and without gaps. If there is a gap, it means that something went wrong, e.g. the internal buffer pool is empty (too many buffers queued up downstream). https://bugzilla.gnome.org/show_bug.cgi?id=781776
