Help! code for specifying .vtt caption file doesn't work!
Hi folks,
I hope this is something simple.....
I'm writing plain jane HTML5 code to play .mp4s on mobile devices that won't play Flash content. I HAVE to have them accessible to the deaf and hard of hearing, so they have to be captioned. I have the caption files for everything, in .vtt format (which this stuff is supposed to recognize).
Here's the code:
<video controls><source src="/sites/default/files/videos/Cathys_voicedintro_draft1.mp4" type="video/mp4">
<track label="English" kind="captions" srclang="en" src="captions/Cathy_intro.vtt" default>
</video>
</body>
When I hit the link to this page in a browser, the CC button appears for just a second or two....then it disappears. The video plays fine. On mobile devices, the video plays fine and the CC option is always there (on some devices) but turning on CC doesn't do anything.
Have I missed something simple? I'm on a serious deadline and this has stonewalled me.
#1 You're going to need more than 1 MP4 file type as some browsers don't support MP4s. I typically use MP4, OGV and WEBM to cover all bases.
#2 Refer to this Mozilla development article on adding captions to videos. Pay close attention to the Caption Menu CSS and scripts.

Code Insight in opened pkb-files doesn't work
If i open oracle package body under Packages node, then opened editor allows me to use code Insight.
If i open pkb-file by double clicking it, compiling it against connected database successfully, and trying to use code insight, then it doesn't work. No helping auto-complete works there.
How can i use autocomplete in pkb-files?

How to write a code for open new txt file in swing
hai all,
now i do one project in java.that project's GUI is Swing. But i don't known swing (basic).So how to write a code for open new txt file and "Open window " in menu item on swing.that means when i click the "New" on menu that time open a new txt file. open also like that type.
plz give me that code ! very urgent
Advance Thanks !
RSKSwing Tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/index.html
Since you don't know the basic of swing read the tutorial, it is for your own good because it is useless if we provide you with a code you don't even understand and how it works.
If you want a menu read the tutorial about using menus and for opening a file read using JFileChooser.
note: don't use the word urgent because it implies that your problem is more important than others. -
I received an email containing pdf files. I am using Adobe Reader Touch for Windows 8. File doesn't open. I am a new user to Windows 8.
The full featured Reader for Windows 8 is Reader XI.
Reader Touch works in all Windows 8 systems BUT it is intended mainly for use in mobile tablets - I see no particular reason to use it unless you can'r run Reader XI. Given it is mainly for use on mobile that can't use Flash, we aren't likely to ever see the development team spending their time on this.
If you want the latest and greatest - at least try Reader XI, not X! (Flash is a separate download, it will prompt). -

JSP referencinc taglib.tld in JAR file doesn't work.
I have some custom tags which work fine under Weblogic 5.1 when I do a
normal deployment of files, including the taglib.tld. However, when I
try to reference the taglib.tld located in a JAR file, then weblogic
throws an error saying that it cannot resolve into a valid tag library.
I am only doing this because I am testing the same site agains both
iPlanet Web Server and Weblogic. iPlanet will only find the taglib.tld
when it is in a JAR file.
Can anyone shed some light on referencing the taglib.tld in a JAR file.
This should work, as it is covered in the JSP 1.1 specification.
FYI - the jar file is in the same location as the JSP which references
it. The URI to the JAR file (in the JSP) is from the root of the site.
Thanks for any help.

Read From Binary File doesn´t work on MCB2400 in LV2009 Embedded ARM
Hello,
I try to read a Binary File from SD-Card on my MCB2400 Board with LV2009 Embedded for ARM.
But the output is always 0, if I use my VI on the MCB2400. If use the same VI on the PC it works fine with the same binary file.
The
access to the SD-Card on the MCB2400 works in other cases finde, if I
try to read from a text-file it works without any problems.
Are thre any constraints for the "Read From Binary File"-Node in Embedded in comparison to the same node on PC ?
I have noticed that there is also a problem
with the reading of textfiles. If the sice of the file is about 100Byte
it doesn´t work anymore, too. I can´t understand it, because I read
always just one Byte. And even if the implementation in Labview is so
bad that it allways reads the total file in the ram it sould work. The
MCB2400 has 32MegaByte RAM, so 100Byte or even a few MegaByte should
work.
But this doesn´t seem to be the Problem for the Binary-Problem. Because even a 50byte Binary-File doesn´t work.
bye & thanks

SD_Card_Read-test.vi 12 KBHello,
thank you for your Help.
But I just want to read a Binary File, which is build by another program. And this is coded with 8Bit (like a normal Binary File) and not just with 7Bit (ASCII). So the workaround doesn't work in my case.
I posted the Test-VI in my first post (here once again as picture). And it works fine on the PC, but if I try it on my MCB2400 the "Read Form Binary File" Node doesn't work.
And it is also possible to open the Bin file with the "Read Text File" Node and see the cryptic content of the Bin-File. So the Problem seems to be in the "Read Form Binary File" Node.
bye & thanks again

Click "Continue" on the "Windows needs your permission" dialog
When Notepad opens, click File and select Open
In the filename field type the following:
C:\Windows\System32\Drivers\etc\hosts
If any entries in the host file include keywords such as "adobe," delete those entries. These are used for Adobe Licensing.
From the "File" menu select "Save" after making changes
Restart Muse
Macintosh
Click on the "Finder" icon. Select the "Applications" folder
Open the "Utilities" folder and select "Terminal"
Type the following:
sudo nano /etc/hosts

Let me know the result -
I am quite new to java so I hope my question is not stupid.
I used bluej to realize an application.It works when executing the main method in bluej,but when I create the jar file,it simpy doesn't work.I have included the main class when creating the jar file.When double-clicking on the jar file, it makes the typical error sound of windows,but it doesn't show any message.

Both Chrome and Safari interrupt online streaming to request/demand an update for a PC program that doesn't work on Macs. What is going on?
The update alerts are fake, and are intended to dupe you into installing malware or disclosing private information so that your identity can be stolen.
You might get the alerts when visiting a website that has been hacked. Don't visit the site again. If applicable, notify the site administrator of the problem, but don't send email to an unknown party.
If you get the alerts when visiting more than one well-known website, such as Google, YouTube, or Facebook, then they're almost certainly the result of an attack on your router that has caused you to get false results from looking up the addresses of Internet servers. Requests sent to those sites are redirected to a server controlled by the attacker. It's possible, but less likely, that the DNS server used by your ISP has been attacked, but you should assume that the router is at fault until proven otherwise.
The router's documentation should tell you how to reset it to the factory default state. Usually there's a pinhole switch somewhere in the back. It may be labeled "RESET." Insert the end of a straightened paper clip or a similar tool and press the button inside for perhaps 15 seconds, or as long as the instructions specify.
After resetting the router, quit the web browser and relaunch it while holding down the shift key. From the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Do the equivalent if you use another browser. Open the Downloads folder and delete anything you don't recognize.
Then go through the router's initial setup procedure. I can't be specific, because it's different for every model. The key points are these:
1. Don't allow the router to be administered from the WAN (Internet) port, if it has that option. Most do.
2. Set a strong password to protect the router's settings: at least ten random upper- and lower-case letters and digits. Don't use the default password or any other that could be guessed. Save the password in your keychain. Any password that you can remember is weak.
3. If the router is wireless, or if you have a wireless access point on the network, use "WPA 2 Personal" security and set a different strong password to protect the network. If the router or access point doesn't support WPA 2, it's obsolete and must be replaced.
During the time the router was compromised, you were redirected to bogus websites. If you ever connected to a secure site and got a warning from your browser that the identity of the server could not be verified, and you dismissed that warning in order to log in, assume that your credentials for the site have been stolen and that the attacker has control of the account. This warning also applies to all websites on which you saw the fake update alerts.
Check the router manufacturer's website for a firmware update.
If you downloaded and installed what you thought was a software update, ask for instructions. -
