您用電腦看Youtube會無法打開或播放幾秒就停播嗎？

pari

會有不同的情形

官方說法
http://helpx.adobe.com/flash-pla ... ernet-explorer.html
A. ie8用戶請回復到預設的設定
Reset to default settings if you are using Internet Explorer 8.

Click on Tools > Internet options 工具..網際網路選項
In the Advanced tab, go to Reset in "Reset Internet Explorer settings". 進階..Reset
Click the Reset tab and follow the prompts.


其它原因: 影片使用ActiveX控制，瀏覽器卻開啟ActiveX Filtering過濾，這時要去關掉選項裡的Active Filtering, 否則有些影片看不到

Additional Information

ActiveX Filtering is a new feature for Internet Explorer 9 which allows you to browse the Web without running any ActiveX controls. Flash Player is an ActiveX control and when filtering is enabled Flash content will not be displayed on a webpage.

When you visit a webpage that contains ActiveX controls, and filtering is enabled, IE will display a circle with slash icon (see screenshot below) in the address bar to indicate that controls have been filtered.

Flash content and video will not be displayed on the page until you have disabled ActiveX filtering. Fortunately, you have a few options for enabling ActiveX content.


B. ie9 要去關掉選項裡的Active Filtering(齒輪圖像/工具網際網路選項..安全..不要勾選ActiveX Filtering)
Disable ActiveX Filtering on Internet Explorer 9

Follow these steps to disable ActiveX Filtering for all websites:

Open Internet Explorer 9 and click on the Gears icon in the upper right corner of the window.
Select the Safety menu, and then uncheck the ActiveX Filtering menu item. Alternately you can also access this via the Tools menu on the menu bar, then unchecking ActiveX Filtering.

如果是個別影片有畫斜線的話，點下去找那個ActiveX Filtering並且把它關掉(勾選關掉選項)
You can choose to disable ActiveX Filtering for individual websites that you trust. Follow these steps:
Navigate to a page with blocked content, noted with the circle with slash icon.
Click the circle with slash icon.
Click the Turn off ActiveX Filtering button.
To the top

其他原因: 改變螢幕解析度會有影響
The video stops playing when you change the resolution (especially in full screen mode)
A black or white box replaces the video
Colors in the video are splotchy
A green line appears splitting the player in two
Seek/navigation bar is missing or displaying incorrectly
Other issues

其他可能
1. 防火牆

其他解決辦法：
快速說明：
解除安裝Flasher Player,
清除登錄項目(這個如果手動來搞的話弄不好會把電腦搞掛)
重新安裝新版Flash Player

細節步驟(這個我沒做過，不要怪我)
(window本來就有解除安裝，為何要抓這個我也不知道，請先自行用window的試看看)
i) 安裝一個"解除安裝"的軟體，叫做revouninstaller
解除安裝 uninstall flasher player
重新啟動

ii) 安裝執行一個檢查/清潔Registry的軟體叫做ccleaner
1. 軟體執行後會check你的電腦的登錄項目
2. Registry Clean
重新啟動

iii) 去get.adobe.com/flashplayer/
抓最新板的Flash Player、重新安裝

[後記]
目前大部分採用H.264編碼的影片，在今年Google釋放授權另外vp8編碼(還有後一代的vp9)後，將來的瀏覽器就不需要用到封閉的Adobe Flash Player Plugin內崁插件了
