I want to develop a j2me application that will play a video file(.mp4) by selecting a particular directory on mobile phone(nokia s40 series).

How do i go about this?can anyone help me to initiate the above said process.

Solution

You need to use JSR-135 and JSR-75 to accomplish this. Check http://www.forum.nokia.com/document/Java_Developers_Library_v2/GUID-96C1B6E4-C266-42A9-9581-A6EEDAC44AC4_GUID-B6B3EB3A-05F6-4CD4-920A-8ED818328681.html for Nokia implementation notes for JSR-75 FileConnection.

Check http://www.forum.nokia.com/document/Java_Developers_Library_v2/GUID-96C1B6E4-C266-42A9-9581-A6EEDAC44AC4_GUID-F227753C-29F7-4056-AB46-1BD80F83E109.html for Nokia implementation notes for JSR-135 Mobile Media.

The Javadocs can be found: http://java.sun.com/javame/reference/apis/jsr135/ and http://www.forum.nokia.com/document/Java_Developers_Library_v2/GUID-D69FC49D-783E-45CE-80D4-7A9F3EE08B2A/overview-summary.html .

Note that only certain directories are exposed via Java ME. You can find information on which folders under the System properties link in the JSR-75 link above.

Basically you want to do this:

Use FileConnection to open a directory and list it contents.
Let the user choose one of the files in the directory.
Create a video player via JSR-135 with the file path as input: Player player = Manager.createPlayer("path_to_the_file");
You also have to attach a VideoControl to the player that associoates a canvas/form to render the video on. (Use VideoControl.initDisplayMode). You also set all the video properties via this control, such as size, location etc.
Then use player.start() to start the playback.

This is a pretty good starting tutorial: http://today.java.net/pub/a/today/2005/09/27/j2me4.html
