Hi,

Calling playMedia() immediately after adding player to panel will always
throw exceptions because it takes some time before the media plugin is
ready. so you can either:
- use autoplay as true when creating the player, or
- register a PlayerState handler on the player and then call playMedia()
after the PlayerStateEvent.State.Ready is called.

Hope that helps
Regards.

Sikiru,

Thanks for your reply. I had this all working before, but after Apple updated their Java that cause problems for many Google Java API users and I updated to new GWT, App Engine and your media player APIs then the media play was no longer working. I am attempting to find why and am implementing the simplest example I can find to work it out. I will try changing to auto play to see if that runs. Other wise I get no error messages, the window opens, it says media has loaded and no play control buttons or movie appear. I will post again if I can't get working. Thank you very much. Robo

Hi,

Please see if you can suggest what is keeping me from seeing mov file from playing/displaying And no player control buttons, like play. No errors, warning or other on hosted dev mode console when this runs.

Code:

    private void initPlayer() {

        VerticalPanel mainPanel = new VerticalPanel();

        player = null;
       
        try {
             // get any player that can playback media
             player = PlayerUtil.getPlayer(Plugin.Auto,
                        "http://www.my_url.com/mn/SaltonSequence.mov",
                        true, "400px", "500px");

             mainPanel.insert(player, 1);    // place in main panel of display

        } catch(LoadException e) {
             // catch loading exception and alert user
             Window.alert("An error occured while loading");
        } catch (PluginVersionException e) {

             // catch PluginVersionException, thrown if required plugin version is not found
            mainPanel.insert(PlayerUtil.getMissingPluginNotice(e.getPlugin()), 1);
        } catch(PluginNotFoundException e) {
             // catch PluginNotFoundException, thrown if no plugin is not found
            mainPanel.insert(PlayerUtil.getMissingPluginNotice(e.getPlugin()), 1);
        }
        player.setTitle("TEST PLAY");

        mainPanel.insert(player, 1);    // place in main panel of display
    }

On an there is a little error-typo in http://oss.bramosystems.com/bst-player/getting-started.html for PlayerUtil class example. See

PluginVersionException ex VERSES e.getPlugin()

Context:

} catch (PluginVersionException ex) {
     // catch PluginVersionException, thrown if required plugin version is not found
     panel.setWidget(PlayerUtil.getMissingPluginNotice(e.getPlugin()));
} catch(PluginNotFoundException e) {

Thank you very much for your time and prompt response.
