Description José Alburquerque 2009-11-24 21:55:59 UTC 
Would it be possible to include a mention in the "Interfaces" section of the GStreamer Application Development Manual that an element should be placed in a PAUSED or READY state in order to use the interfaces that it may implement like GstMixer?  Some C++ coders apparently need information like this specified clearly to know how to use these interfaces.

Good idea:

    docs: improve GstMixer and GstTuner docs
    
    Mention that elements implementing GstMixer and GstTuner need to be
    in the right state before they can be used. Also mention GLib
    functions for converting filenames to and from URIs.
    
    Fixes #602877.

This is a problem everyone runs into really (and the warning is very misleading). Unfortunately we can't fix this horrible GstImplementesInterface stuff before 0.11, but it's scheduled to be removed next time we break API/ABI.
