Hi Maun Suang,

Thank you for the fix and the explanation; it is much appreciated. In
the case of the flag fix, it would be very useful if you could report
this to the ffmpeg-user list at
http://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-user, since the
misbehavior appears to be general for the platform rather than being
MacPorts-specific.

Best,
Dave
