目标：aHR0cHM6Ly90di5jY3R2LmNvbS8yMDI0LzA2LzI0L1ZJREV6Rnc1ZGZ1OEQ2NFh0a3Z0Yml6bTI0MDYyNC5zaHRtbA

urlJson：https://vdn.apps.cntv.cn/api/getHttpVideoInfo.do?pid=2d30ad68d8ae4b2a9ff47dc0b51d5889

通过上方字段（hls_url）
https://newcntv.qcloudcdn.com/asp/hls/main/0303000a/3/default/2d30ad68d8ae4b2a9ff47dc0b51d5889/main.m3u8?maxbr=2048
替换成下面这个
https://newcntv.qcloudcdn.com/asp/hls/2000/0303000a/3/default/2d30ad68d8ae4b2a9ff47dc0b51d5889/2000.m3u8?maxbr=2048

获取到的这个清晰度太低了，看论坛的网友说5.30后这种访问就获取不到最高的清晰度，请问下大佬们 高的清晰度如何获取？？？
