    capture of video in video/3gpp encoding on N95

    Hi

    Im trying to write proper application on N95 to capture video in available encodings for N95.

    To detects which codecs available for capturing I'm using

    String[] act = Manager.getSupportedContentTypes("capture");

    so results is
    video/3gpp
    video/3gpp2
    video/mp4

    so my locators were

    capture://video?encoding=3gpp
    capture://video?encoding=3gpp2
    capture://video?encoding=mp4

    All the time Im getting MediaException : Not supported

    Only way to make video is using
    capture://video
    then it's creating player. When I tried to detect content type it detected as video/3gpp.

    Any ideas how to use all supported encodings?

    Thanks

    The video encoding format is somewhat hardcoded with the resolution, like this:
    176x144, 15 fps - 3gp
    352x288, 15 fps - mp4 (not supported on N95)
    320x240, 15 fps - mp4
    640x480, 30 fps - mp4

    So if you want more than 176x144, the format will always be mp4 (that's at least my experience when dealing with video formats in Symbian C++).

    I think the only way to change from the default quality (176x144) is to use CameraControl in AMMS (JSR 234), this of course assumes your device supports AMMS.
