avformat/av1dec: Flush BSF upon seeking The av1_merge_frame BSF outputs its cached data when it sees the beginning of a new frame, i.e. when it sees a temporal delimiter OBU. Therefore it typically has a temporal delimiter OBU cached after outputting a packet. This implies that the OBU demuxer must flush its BSF upon seeking because otherwise the first frame returned after a seek consists of an old temporal delimiter OBU only.
