If the decoder was not able to decode a frame because insufficient information was available, e.g. missing sequence or picture header, then allow the frame to be gracefully dropped without generating any error. It is also possible that a frame is not meant to be displayed but only used as a reference, so dropping that frame is also a valid operation since GstVideoDecoder base class has extra references to that GstVideoCodecFrame that needs to be released.
