    Default Seekable media formats

    Is there a list of media formats / codecs that are seekable? (Phonon::MediaObject::isSeekable()) I assume seekability is codec related. I would like to freely go to any time position on video. Does the seek() function guarantee access accuracy in individual frame level or is it possible, it will seek a keyframe or something nearby?

    Look at SeekSlider. It has such method
    Qt Code:
    1. void setSingleStep ( int milliseconds )
    To copy to clipboard, switch view to plain text mode

    I'm not worried about the user interface (ie. slider) ability provide me the time, but rather the underlying media seek. I'm going to synchronize video clips with other stuff so I need to be sure it really seeks to the given time. Currently I'm working on Java + JMF, which only provides seekability to some ancient media formats. I may change the platform to cpp + qt if better support for these requirements is available.
