ffmpeg | branch: oldabi | Reimar Döffinger <Reimar.Doeffinger at gmx.de> | Wed Jun 22 18:25:49 2011 +0200| [3fedb3e65c6595c4fd78b03ed9b0d83cf257062c] | committer: Reimar Döffinger

Revert needless API change in 05e84c95.

When providing a custom AVIOContex for a AVFMT_NOFILE format
only print a warning instead of erroring out.
This allows the code to work with older MPlayer versions that
just always set pb out of laziness.
