    Ok,
    I have a IP camera support MPEG4 format streaming,
    I plan to do:
    once I send a cgi request and receive the streaming data then parse them to get a lot of MPEG4 frames,
    how can I use API to decode the MPEG4 frame to BMP and show on the screen?
    Is API available? or decode the frame by myself?

    I suspect that there are no such ready-made APIs. You have to decode the data yourself, and doing so in J2ME is probaby not going to be very fast.

    Note also that with MPEG formats, there may be licensing issues, if you write the code youself: http://www.mpegla.com/main/default.aspx

    thanks for the replys!

    petrib:
    if I want to decode by myself, the speed will be a issue, and licensing issues seems a major issue,
    can I avoid the licensing issues?
    I mean that if any lib(or dll) is avaiable and licensing issues can be avoid?
    I searched the following:
    1. xuggle
    2. FFmpeg
    3. FMJ
    4. MPEG decoder in Java ME(http://wiki.forum.nokia.com/index.ph...der_in_Java_ME)

    any suggesion?
    thanks in advance

    Hello,

    on www.click2stream.com we can get h.264 (not mpeg4) stream for your camera (if it supports RTSP) and play the stream in Flash, iPhone and other mobile devices. We can also do a snapshot from a stream and we are working on API, so you can call the "makesnapshot" via JSON API when you want. In this time, I don't have idea how many images we will be able to do in per second. If you want, write me to peter(at)click2stream(dot)com for more informations.
