how to resolve the problem that Chrome 66 turning off autoplay released in April 2018 about xgplayer HOT 12 CLOSED

Chrome calculates MEI score for sites. policy autoplay When MEI is high enough, media playback without muted is allowed to autoplay on desktop only. Maybe the official site of xgplayer in your Chrome gets a high MEI.
The autoplay MEI computation method of Chrome is inexplicit for users, so we suggest that you should give up the plan that autoplay without muted.

In Chrome, muted autoplay is always allowed. See the policy. So autoplay is available in xgplayer with config "volume: 0".

In my project my video still cant auto play at chrome 68.0.3440.84 on macOS High Sierra, i suspect It be effected the warning message:

Failed to load http://img-test.aixuexi.com/B:1005:K/1532448000/0caeb04be45a4447b9896015eb1bf02c.mp4: Request header field Range is not allowed by Access-Control-Allow-Headers in preflight response.

i add the config: ### crossOrigin: true
it still has warning.
i dont know why?

official demo can auto play. it url: http://h5player.bytedance.com/examples/

@zhangzs000 If you are trying to use xgplayer with xgplayer-mp4 plugin, your video server should support range request. With range request, the warning will not happen again.
The config "crossOrigin: true" is unnecessary.

from xgplayer.

operating environment：

mac
chrome 68.0.3440.84（正式版本） （64 位）

i remove the the plugin xgplayer-mp4, no warning "Request header field Range is not allowed by Access-Control-Allow-Headers in preflight response." in chrome now. but it still cant auto play.

so i suspect the reason is asynchronous request then i change the ajax to synchronization，It still cant auto play.

now i dont know why it cant auto play on chrome?

i use xgplayer "version": "1.0.5" in vue project

from xgplayer.

@zhangzs000 Did you config "volume: 0"?

from xgplayer.

config volume: 0 also didnt work.
config muted: true, also didt work.

Muted autoplay in Chrome is supported by a30892. You can try with the branch now or wait for v1.0.8 as soon as possible.
