java对接云点播上传视频并且自动触发转码任务回调更新成m3u8格式的视频

前端拿到签名上传文件，签名加转码参数会触发转码任务，转码任务完成会回调设置的回调接口

 /*** @desc:获取上传签名* @date 2022/12/29 15:57*/@Overridepublic String getSignature() throws Exception {// 签名有效期：2天int signValidDuration = vodConfig.getSignValidDuration();// 设置 App 的云 API 密钥return UploadSignatureUtil.getUploadSignature(vodConfig.getSecretId(), vodConfig.getSecretKey(), signValidDuration);}
