[FFmpeg-user] side data type

Since upgrading ffmpeg to a December build, I am getting a warning "unknown
side data type 10 (24 bytes)".  What does this mean?  I'm using the
MacPorts builds, and this appeared sometime between July and December of
2015.  It would be great to identify this so it doesn't display warnings.
