Error message :
We're sorry, Ligthspark encountered a yet unsupported flash file
SWF file: http//www.metoperafamily.org/met_player/_swf/video/brightcoveplayer.swf
Cause: Null::serialize not implemented

I have to ressort to the non-free and insecure flashplugin-nonfree.

System : debian sid, web browser iceweasel.

In V0.7.0, nearly same url* still cannot be played, but the behavior is different : a grey rectangle with a picture "Met opera on demand" is displayed, and nothing append.

Attached is the output of iceweasel : I got a few errors and some not implemented stuff. I don't know witch one of them is the more relevant.

Errors :
ERROR: Resize not supported
[...]
ERROR: No such Id on dictionary 14 for http://admin.brightcove.com/viewer/us20121113.1511/federatedVideo/BrightcovePlayer.swf?uid=1353137029951
ERROR: Exception in FillStyle parsing: Could not find an object on the dictionary
[...]
ERROR: Internal exception while parsing RPC message

Please let me know what I can do to help on getting this working (other than implementation) and thanks for your great job.
