Evening,

I have just built ffmpeg:

ffmpeg version N-78589-g5f5467e Copyright (c) 2000-2016 the FFmpeg

  built with gcc 4.4.7 (GCC) 20120313 (Red Hat 4.4.7-16)

  libpostproc    54.  0.100 / 54.  0.100

There seems to be some new functionality regarding whitelisting which I can
find reference to in the mailing lists, but am still a bit fuzzy one.

Historically, I could open a locally stored SDP file using something
similar to:

ffmpeg -i tmp.sdp ......

Now however this returns me the error:

Protocol not on whitelist 'file'

There seems to be some reference to this as a possible issue here:

http://article.gmane.org/gmane.comp.video.ffmpeg.devel/208702/match=whitelist

But I'm still not sure as to what has changed, and how I could/should work
around it. Any suggestions welcome :-)
