    Re: Help needed..

    U will have to modify the code based on the format of the video that you wish to cut.You may have to dig into how each and every format works and analyse what each byte means for that format.

    The mp3 cutter must have been able to extract the audio component alone from the video I guess.I am not sure.

    The logic i thought is that to get the frames between the time(cut time) convert them to byte array and write.. But how to get frames and byte array from those??

    MP3 has a simple framing, http://en.wikipedia.org/wiki/MP3#File_structure, which makes cutting relatively easy.
    When there is video, things are a bit more complicated. Have you checked things described in http://en.wikipedia.org/wiki/ISO_base_media_file_format, perhaps some specifications, like http://www.etsi.org/deliver/etsi_ts/...44v110100p.pdf ?

    For Symbian, Movino has an FFMPEG port, which may include video editing features too. http://sourceforge.net/projects/movino/, there seem to be something for Java ME too, but I have never checked what it is.
    For Android, an obvious search for android video cut api brings suitable results ("Android sdk cut/trim video file" from StackOverflow).
