Sharing youtube video from website via facebook -

-

i'm struggling sharing youtoube videos website via facebook.

i'm trying achieve following: want share video hosted on youtube. video should playable on facebook. next video need have title , description. title links website, people can share video. this:

enter image description here

however end this: enter image description here

i can correct "layout" of share image on left, , text on right, og:image meta tag points non-existent image (404).

as og:image meta tag points existing image, layout changes. why happen? i'm lost.

is format of image? (470*236) purpose crucial image , text shared, since text (actually title) links website should shared.

also strange, when i'm debugging "open graph object debugger" looks supposed to. sharer.php delivers correct "view" on 50% of ocasion. when shared, works when have 404 on og:image.

this content of "og:video" tag:

{    "url": "http:\/\/www.youtube.com\/v\/7mavg2bfthc?autohide=1&version=3",    "secure_url": "https:\/\/www.youtube.com\/v\/7mavg2bfthc?autohide=1&version=3",    "type": "application\/x-shockwave-flash" }

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
