here is a sample code:

以下是一个示例代码：`

tried to edit the rtmpurl , tried different streaming platforms, tried reducing the settings of the video parameters eg bitrate, width,height still video is not bieng pushed. The AgoraRtmchannel &client tried to update SDK package but is already upto date .

尝试编辑rtmpul，尝试不同的流媒体平台，尝试降低视频参数的设置，如码率、宽度、高度，静止视频不是必推的。AgoraRtmChannel&客户端尝试更新SDK包，但已是最新的。
