     lavfi: add select filter

     Address trac issue #92.
 }}}

 You can use the filterchain:
 -vf select="eq(pict_type\,PICT_TYPE_I)"

 for selecting only the I-frames to send to the output.

 Note that you'll have still to decode all frames, since we currently don't
 have a packet-level filtering mechanism.
