【求助】【TuyaOS SDK】回到预览界面，服务器不发video start消息

[jiejun.huang]

我们测试到按照如下流程操作，回到预览界面，服务器不发video start消息：
进入app预览，点击回放进入回放界面，然后按门铃推送来电提醒，手机端点击接听，然后挂断，回到回放界面，再返回预览界面，这时候没有video start消息，app没有预览图像。log如附件，麻烦帮忙分析一下这样正常吗？

1.请问是必现的吗，如果好复现，复现后，上传一下APP端日志，并提供一下APP账号，谢谢

[jiejun.huang]

不好复现，等复现后，我把手机log上传后，再在这边回复。

[jiejun.huang]

手机app log已经上传：
LOG上传时间：10：58
账号：18923790502
设备ID：6c555cc5ca63228e58osil
手机型号：iPhone 11
回放界面按门铃，接听后连按门铃，挂电话，回预览不出流

[fallen-queen]

1.附件里面没有10:58对应的日志。

[jiejun.huang]

手机log是10:58上传的，问题发生在10:33分

[fallen-queen]

出现问题后，请问有试过退出APP，重新拉流吗？目前怀疑，应用层的回调__TUYA_APP_p2p_event_cb可能卡住，

麻烦确认一下会不会有这种情况。

[jiejun.huang]

退出app重新拉流能正常出图

[you.xu]

在__TUYA_APP_p2p_event_cb中返回加了打印后测试，可以确定这个函数没有卡住
代码片段如下：

Code: Select all

    case TRANS_STREAMING_VIDEO_START: {
        TRANSFER_SOURCE_TYPE_E *pSrcType = (TRANSFER_SOURCE_TYPE_E *)args;
        DEBUG_INFO("streaming start type %d\n", *pSrcType);
        break;
    }
    case TRANS_STREAMING_VIDEO_STOP: {
        TRANSFER_SOURCE_TYPE_E *pSrcType = (TRANSFER_SOURCE_TYPE_E *)args;
        DEBUG_INFO("streaming stop type %d\n", *pSrcType);
        break;
    }
    default:
        break;
    }

DEBUG_INFO("p2p rev event cb end.\n");
return 0;
}
