Question

我已经编写了一个基于工具箱中FLVPlayback组件的非常基本的flash播放器，然后由SWFObject放在页面中。由于某些原因，即使缩放模式设置为EXACT_FIT，视频上方和下方也总会出现黑条。这对我来说没有意义，因为预览图像被设置为相同的x，y位置和高度＆amp;宽度作为视频，但它完全适合，没有黑条。

我缺少一些简单的东西吗？我为大量的代码道歉但我不确定你怎么必须看到。

我正在使用SWFObject为玩家注入以下代码：

<script type="text/javascript">
var flashvars = {
   playerSkinURL: 'SkinUnderPlayStopSeekFullVol.swf',
   videoURL: 'video.flv',
   previewImageURL: 'video-preview.jpg',
   scaleMode: 'exact',
   autoBegin: false,
   playerColour: '#cccccc',
   playerAutoHide: false,
   playerAlpha: 0.85
};
var params = {
 allowfullscreen: true,
 quality: 'best',
 wmode: 'window'
};
swfobject.embedSWF("video.swf", "video", "479", "310", "9.0.0","/video/expressInstall.swf", flashvars, params);
</script>

<div id="video"></div>

我的动作脚本全部在第1帧：

stop();

/**
 * Embedding this player is simple with the following flashvars API
 * playerSkinURL   = the url to the skin to use eg. SkinUnderPlayStopSeekMuteVol.swf
 * videoURL        = the url to the video FLV file
 * previewImageURL = the url of the image to use for the preview image (43px less than total height)
 * scaleMode       = scale mode of the player
 *        - exact (default) = fit to player dimensions exactly
 *        - no              = use FLV original dimensions
 *                     - aspect    = scale the video whilst maintaining aspect ratio
 * autoBegin       = automatically start playing the video as soon as it is ready (true or false) default = false
 * playerColour    = the colour of the bezel default = 0x47ABCB
 * playerAlpha     = the alpha transparency of the bezel default = 0.85
 * playerAutoHide  = whether to hide the bezel when the mouse is not over it (boolean true or false)

Answer 1

wmode="transparent"可能会有所帮助你也可以在你的flash应用程序中应用一个掩码来隐藏条形图，但如果问题不存在于独立的FP中，那么它就会被插入到HTML / js中，因此应该修复它。
scale: "noScale"也很有用（但您必须调整播放器或html容器的大小）

Answer 2

事实证明我正在使用JS扩展闪存，但我真正想要的是Flash组件保持其相对于可查看/ Flash窗格边缘的位置。我不希望它们伸展或扭曲。

这必须通过使用ActionScript绘制控件等而不是使用默认的播放器外观以编程方式完成。看看一个开源播放器的来源，你会看到我的意思。当播放器处于全屏模式时，这也会阻止控件显得模糊。

此外，源视频在视频的上方和下方都有一些小条，但没有我试图在此处删除的那些大。

即使精确缩放，Flash AS3 FLVPlayback组件也始终在视频上方和下方显示黑条
