The CTL has released a new AIR application called LiveStreamer available now via the Adobe AIR Marketplace.
This started as a simple mechanism to display a live RTMP stream from Flash Media Server to a client machine and related projection system in anticipation of an upcoming live, campus-only event. So… not for broadcast over the web- just sending a live stream from one physical location to another.
While developing the application, I came across the need to test an RTMP stream and it was so simple using this app that I decided to expand it. In the current version (0.9.0), it will accept RTMP and HTTP streams- just type in the URL and you can easily test it in order to verify that it is correct before trying to publish anything on a website or whatnot. You can also use it as a fullscreen projection or display mechanism as was originally intended.
If you have some FLVs or MP4s or whatnot on your local machine- you can just drag those into the app to watch them. I’m thinking about adding some playback controls and other options a bit later.
Application for display of video streams via RTMP, HTTP, or local filesystem. Just drag in a file or enter a stream address and away we go!
At the University of Denver, we have built a good number of AIR applications at this point. Some are internal data management tools, others are full, complex, private applications such as the VPS Projection system, and then we have small utility apps like this which others may also find some use for. These we make available to others free of charge as part of our community outreach.
CTL has released an update to the CourseMedia™ Media Viewer today which includes 2 enhancements:
This may be a good time to explain the version numbering system in place. The version string contains 3 positions; the first being the whole version number, second is increased upon an addition or enhancement, the third is reserved for bug fixes and issue resolution.
One of the main issues we get called on regarding the DU Portfolio Community is in regard to text formatting. In 2007, we included the TinyMCE WYSIWYG text editor in biographical descriptions and item descriptions. While this does give DUPC users a lot of freedom in the way they style their text, it also opens the door for a lot of problems.
Basically, if a user is nor careful, text fields may end up with a bunch of formatting tags that will need to be stripped out:
The best way to do this is to just copy your text into something like Notepad first, then copy out of Notepad and paste into DUPC. Notepad (or an equivalent plain text editor) will definitely strip out these tags for you. There is also a plain text insertion button on the editor that may help in this:
This problem can also be a result of pasting content in from Microsoft Word or similar apps which will carry over a lot of extra data like this:
TinyMCE also includes a button to paste text in from Word which helps clean it up a bit:
There is even an option to edit the HTML if you really need to get in there deep:
