Okay, I find the object 'movie' inside the object 'player'.
<DefineSprite objectID="131" frames="1">
//.....
<PlaceObject2 replace="0" depth="1" objectID="130" name="movie">
<transform>
<Transform scaleX="1.000000000000000"
scaleY="1.000305175781250" transX="0" transY="-317"/>
</transform>
</PlaceObject2>
//.........
</DefineSprite>
<PlaceObject2 replace="0" depth="1" objectID="131" name="player">
<transform>
<Transform transX="4500" transY="3700"/>
</transform>
</PlaceObject2>
But the question remains is why Gnash can't find the function
setMovie() when it tries to execute this:
Flare output:
frame 1 {
movie = player.movie;
movie.base_url = '/';
movie.tracker_cls = logic.PlayerTracker;
movie.setMovie(video_id, undefined, undefined, l, t);
movie.playMovie();
Stage.scaleMode = 'noScale';
Stage.addListener(this);
onResize = function () {
player.resize(Stage.width, Stage.height);
};
In the flare output, setMovie is defined here:
movieClip 141 __Packages.logic.Movie {
logic.Movie = v1;
logic.Movie extends MovieClip;
var v2 = v1.prototype;
v2.initController = function () {
//........
};
v2.setMovie = function (_video_id, image_url, movie_url, l,
_track_id, eurl, append_vars) {
//..........
}
any more help is appreciated...
Thank you again.
