问拉取远端视频一直失败？

2016/11/30 120053.959| I| 26998| av_room_multi_impl.cpp(922):GetEndpointById ERROR. GetEndpointById failed. identifier = 126128719.2016/11/30 120053.960| I| 26998| av_request_view_impl.cpp(58):RequestViewList **RequestViewList. count = 0, complete_callback = 0x157f57410. 2016/11/30 120053.960| I| 26998| av_request_view_impl.cpp(64):RequestViewList ERROR. AV_ERR_INVALID_ARGUMENT. QAVMultiRoom multiroom = (QAVMultiRoom )HMLiveBuilderContext builderContext.room; NSArray requestList = @@"24835532"; NSArray srcList = @[NSNumber numberWithInt:QAVVIDEO_SRC_TYPE_CAMERA]; multiroom requestViewList:requestList srcTypeList:srcList ret:^(QAVResult result) { if (result == QAV_OK && succ) { succ(); } };主播的identifier一直都是24835532，我也推流成功咯，房间号500000，主播和观众都进入房间成功，为什么就是不成功呢？
