I used the picture to customize the loading bar, and want to hide the default loading bar, how to do ?
Do you mean the video progress control that appears in the control bar?
If so, you can remove it with a function call like player.removeChild('ProgressControl') before adding your own progress control.
thanks,i tried, failed,

i want to hide this:

Ah, the spinner. You could use this CSS, which has to come after video.js' CSS:
.vjs-seeking .vjs-loading-spinner,
.vjs-waiting .vjs-loading-spinner {
display: none;
}
it work, thank u~
