背景音乐播放时部分机型播放报一下错误，但并不是所有音频都不行，具体原因是什么？这些音频播放不了是什么原因造成的？ 错误信息：{"src":"http:\/\/audio.winnerbook.com.cn\/202004\/yqdjw_1.mp3","errCode":10001,"errMsg":"errCode:67, err:decode audio fail"} 系统信息（下面是两个播放不了的机型系统信息）：{"screenWidth":360,"windowHeight":667,"bluetoothEnabled":false,"language":"zh_CN","microphoneAuthorized":true,"locationAuthorized":true,"notificationAuthorized":true,"model":"COR-AL10","statusBarHeight":30,"safeArea":{"width":360,"right":360,"top":30,"left":0,"bottom":740,"height":710},"brand":"HONOR","windowWidth":360,"locationEnabled":true,"benchmarkLevel":19,"screenHeight":740,"abi":"arm64-v8a","version":"8.0.1","cameraAuthorized":true,"system":"Android 9","fontSizeSetting":16,"pixelRatio":3,"deviceOrientation":"portrait","wifiEnabled":false,"screenTop":73,"platform":"android","SDKVersion":"2.16.0","enableDebug":false,"devicePixelRatio":3,"host":{"env":"WeChat","version":671089117}} {"screenWidth":360,"windowHeight":710,"bluetoothEnabled":true,"language":"zh_CN","microphoneAuthorized":true,"locationAuthorized":true,"notificationAuthorized":false,"model":"TAS-AN00","statusBarHeight":27,"safeArea":{"width":360,"right":360,"top":27,"left":0,"bottom":780,"height":753},"brand":"HUAWEI","windowWidth":360,"locationEnabled":true,"benchmarkLevel":25,"screenHeight":780,"abi":"arm64-v8a","version":"8.0.2","cameraAuthorized":true,"system":"Android 10","fontSizeSetting":16,"pixelRatio":3,"deviceOrientation":"portrait","wifiEnabled":true,"screenTop":70,"platform":"android","SDKVersion":"2.16.0","enableDebug":false,"devicePixelRatio":3,"host":{"env":"WeChat","version":671089209}}

微剪插件导出的视频清晰度变低了，而且视频大小也特别大，3.9MB(960 × 544)的视频导出后有54.1MB(1270 × 720),清晰度还变低了，而且封面图片是空白图，怎么解决，导出的视频如何直接上传到云点播？
