Css Video.js细黑线

我正在使用great video.js库为我的站点创建一个自定义HTML5视频播放器。不幸的是，在Safari中，玩家的右侧出现了一条细黑线。有时，调整浏览器大小可以解决问题，但我认为这是一个bug

以下是我根据以下内容更改玩家皮肤的部分：

我不知道为什么会这样。这可能是视频的问题吗

我能够解决这个问题。我正在使用的视频的纵横比并不完全适合播放器。我调整了.video js顶部的填充来修复它

// The main font color controls the color of the text and the icons (font icons)
@main-font-color: #CCCCCC; // e.g. rgb(255, 255, 255) or #ffffff

// The default color of control backgrounds is mostly black but with a little
// bit of blue so it can still be seen on all black video frames, which are
// common.

@control-bg-alpha: 0.7; // 1.0 = 100% opacity, 0.0 = 0% opacity

// The slider bar color is used for the progress bar and the volume bar
@slider-bar-color: #1A6DBA; // e.g. rgb(255, 255, 255) or #ffffff
// The background of the progress bar and volume bar have a lined pattern that

// The "Big Play Button" is the play button that shows before the video plays.

// where it gets out of the way of valuable content in the poster image.
@big-play-align: center; // left, center, or right
@big-play-vertical-align: middle; // top, middle, or bottom
// The button colors match the control colors by default but you can customize
// them by replace the variables (@control-bg-color) with your own color values.

// The font size is what makes the big play button, big. All width/height values

// Now that font size is set, the following em values will be a multiple of the
// new font size. If @big-play-font-size is 3em (30px), then setting the any of
// the following values to 2em would equal 60px. 2 * font-size
