hi,

a fellow named DANIEL KAISER (EMPH I DID NOT CONTRIBUTE ANYTHING HERE) took some time to contribute an 'movflags' option for people STUPID enough to buy APPUL products that, of course, have an equally stupid and BUZZY name like RETINA.

since it works and it would be convenient to mainline, even though stupid people don't deserve it, per carlos' suggestion i have taken a minute to update the patch so it jives with the latest git.

it's attached. thank you daniel kaiser. 

remember ffmpeg team: should the patch meet your criteria for introduction, please be sure to  insult and berate the APPUL users because they need it.

bless,
g
