I am working on a project where I need to create a Video/audio player in java that will allow a user to select a file they want to play and it to play that file. In the future, I am going to get the program to print the conversation of the audio/video file in real time, So i need to some how to create a video/audio player which has a elapsed time which I can be extract for the other component of the software.
I wondered if anyone could suggest some libraries for me to use or give me any advice they think could help me!
Thanks in advance!
I'm not sure what you mean by "print the conversation" but if the issue is knowing how far into the playback stream you are (i.e., elapsed time) then any media player I've diddled with has the ability to establish a listener that gets periodic update events. If your target environment is Android then you can simply use the android.media.MediaPlayer. I've had good results with it. I can't, however, give you a recommendation for a non-Android Java environment.
Also you need to be aware that there some video formats (e.g. Quicktime) may not be supportable with a given player.
You may take a look on Xuggler. Also some alternatives to JMF were covered in Wikipedia.

I want to read content(text data) from jpg image. Can someone give me a sample java program to refer.
The image would be a white page. The text would be in black. How do I extract data(lines/alphabets) and print it.
Help would be much appreciated.
Thanks
Take a look at this SO question for OCR in Java. Once you are able to pull out the text, doing manipulations on the text can be taken care of by using Apache Lucene. Also, in case you are interested in image metadata as well, Apache Tika might be useful.
Pay attention for products by ABBYY. For example there is ABBYY Cloud OCR SDK – cloud-based OCR technology. It has very high recognition accuracy, a lot of documentation and good support.
You can try to use it in several easy steps:
1. Create a free account
2. Create an application using code samples for Java
If you need additional help, use ABBYY's forum or publish your questions in comments below.
I work for ABBYY and ready to help you.

I am developing a Blog kinda app where a user can upload images, videos, text, etc.
My problem is that I wanted to stop the users from uploading any explicit content. I need to check whether the image or text contained with any explicit or bad content. Till now I am not able to check if the text contains any explicit contents. In this, I compare the textual words with my database word dictionary. But I feel it is not a perfect solution as the number of words are too many. I wanted to know if this kind of checking is feasible and if it is not possible to do so, then any suggestions that I should follow and most importantly in the case of images. I am ready to use any API if it exist for such problems.
If there are any specific libraries in other platforms can also be helpful for reference purpose.
If you would like to remove spam it is a nice to consider Akismet. (Wordpress installations come with default integration.) There is an another widely used one called SpamWipe.
If you would like to check Plagiarism, there are other tools like the one that small seo tools is providing. You can take a look at copyleaks.com too.
There is a good list for API-s to use in your case:

Of course you could use this kind of API-s in your application.

i am wondering if there is any opensource and freeware solution to extract roads from an image, like google map images?
i think it maybe possible to code something like that with AI solutions, but i dont know where to start
thnx
If you're mainly interested in the results, instead of an algorithm, you may want to check out OpenStreetMaps.
Otherwise, you should focus on computer vision solutions and a framework such as OpenCV in order to process raw imagery and filter out streets based on their features – which is not trivial.
This sounds like it would be a valuable resource to cartographers ranging from 'street directory' publishers to the military.
I'm sure proprietary commercial software exists, but open source and freeware — probably not.

I need an open source GIS that allows one to view/zoom/click the maps using a web browser and should be java compliant (deployable on a java app server).
Well, I have tried to structure the requirement in 'what-i-have' and 'what-i-need' lists:
Inputs:
Location: lat/long
Data : Text to display
zoom level: (assume there are about 5)
Output
Data displayed on a Map
Would appreciate all the help I can get.
Thanks.
UPDATE: GeoServer + OpenLayers seems to be the best fit for this requirement
GeoServer: http://geoserver.org/display/GEOS/Welcome
...is what I use. You have work ahead of you no matter what you pick, though. Setting up data sources and making them look nice is a decent amount of effort.
For the client side, OpenLayers is an excellent Javascript library.
I agree with the geoserver response and all the rest of the responses ignore your statement that is has to work with Java. The only other bad option would be to write something yourself using geotools.
Go to the OpenGeo site and see the stack they support. That is the stack you are probably most interested in deploying.
I guess you'll need:
GDAL/OGR to translate the data into a kml file example
Take that KML file and pump it into either:
a. Google maps api or openlayers
b. I've had lots of luck using featuresever which I personally recommend

I'm looking for a Java framework to help with some data mining specific to images. We have a set of historical images that I would like to categorize and classify. I'm was hoping to find something like weka http://www.cs.waikato.ac.nz/ml/weka/ or Marsyas http://marsyas.sness.net but more specific to sifting through image data to find patterns. Any suggestions?
What about using the OpenCV library for Processing? Technically, Processing is not Java, but it runs on the JVM and shouldn't be difficult to get working. OpenCV is the standard choice for computer vision, which is what you're trying to do.
I played around with Neuroph (http://neuroph.sourceforge.net) which is a neural network framework for Java, and they have a very nice image recognition tutorial that I think everybody should read, but specially if you're dealing with image recognition: http://neuroph.sourceforge.net/image_recognition.html
Have a look at OpenCV with JavaCV libraries from Google. Simply use function from that library to find whatever patterns you want.
It'll be a great surprise for me if you can find such library.
I can advice you to find some library with ART neural network implementation. Then you can add some photos to each category you want to recognize and ART algorithm will try to recognize all other photos.
