patch to fix the issue.

when streaming H263 stream on RTSP, asteriskh263 will be loaded. but can't find this kind of video decoder. decrease the rank as havn't this kind of decoder.

This seems correct, it should probably have a lower rank than the normal h263 depayloader. And I guess ideally this conversion mechanism should be inside that depayloader or even h263parse (I don't know what exactly the difference between normal h263 and the asterisk variant is).

    asteriskh263: Un-rank clashing depayloader
    This depayloader clash with the standard one for H263p. It produces an
    H263p stream with a modified header. It uses encoding-name that is the
    same as H263p (H263-1998) though the resulting ES is not decodable or
    parsable in GStreamer, making it unsuable in dynamic pipeline. This
    patch unrank this specialized depayloader since it can only be used in
    custom pipeline.
