解答:EasyDSS视频点播时音频是否可以设置为默认开启?
2022-07-02 09:53:00 【EasyDSS】
EasyDSS视频直播点播平台集视频直播、点播、转码、管理、录像、检索、时移回看等功能于一体,可提供音视频采集、视频推拉流、播放H.265编码视频、存储、分发的视频流可覆盖全终端等视频能力服务。
有用户询问,为何EasyDSS视频点播时音频默认是关闭的,且分享链接播放也需要手动点击开启音频,能否在平台里统一配置音频为开启状态?今天在本文中和大家做一个专业的解答。
默认音频关闭其实是浏览器的机制,Chrome、Safari、Firefox、Edge等浏览器都在某版本后限制了audio自动播放的功能,必须要用户与当前页面有交互后,才能激活自动播放,否则报错。也就是说,不允许有音频的网页视频在第一次自动播放时有声音,必须要点击音频按钮才可以。
Chrome浏览器提供的允许自动播放的条件:
1)静音状态下始终允许自动播放;
2)有声音自动播放时:
① 用户已与域进行了交互(单击,点击等);
② 在台式机上,已经超过了用户的“媒体参与度索引”阈值,这意味着该用户以前曾播放带声音的视频;
③ 用户已将该网站添加到他们在移动设备上的主屏幕,或者在桌面上安装了PWA。
3)主站可以将自动播放权限委托给它们的 iframe,以允许自动播放声音。
目前EasyDSS平台分享的流地址默认是自动播放的,所以,如果有用户有相关需求,比如视频画面和音频用同一个按钮控制,也可以进行个性化定制。
随着视频直播行业的蓬勃发展,视频直播点播平台EasyDSS在该领域的应用也得到快速普及。EasyDSS灵活可拓展的视频能力,很适合OTT TV、IPTV、互联网教育、视频聊天、现场直播和VOD等应用,结合无人机直播推流,还能实现城市航拍、森林防火、秸秆焚烧、电力巡检等。感兴趣的用户可以前往演示平台进行体验或部署测试。
