支持音频且增加延迟控制选项，如果画面或音频延迟大于指定数值，将直接丢弃数据包，避免画面延迟卡顿（画面会在丢包后出现重影等现象）
Supports audio and adds delay control options. If the image or audio delay is greater than the specified value, the data packet will be discarded directly to avoid image delay and freeze (the image will have ghosting after packet loss).
