[vdr] ERROR: attempt to open OSD while it is already open - using dummy OSD!

2008-03-16 Thread Wolfgang Rohdewald 
start the osddemo plugin and then

echo -e "MESG hallo\nQUIT" |nc localhost 2001

gives me the above error message with vdr 1.5.16

and the message will never be visible.

how can a plugin like a music player handle this
correctly? It always has an open osd, but of course
hides it with Hide(). 

But vdr does not ask the plugin to hide before trying
to show the message, so I am getting the same error
message in that situation. I see no way to get rid of it.

As a possible solution, can the player control somehow
tell vdr that it can handle the message display itself?
Something like

class cControl : public cOsdObject {
public:
  ...
  virtual bool DisplayMessage(...) { return false };

so if a player is active, its DisplayMessage is called.
Only when it returns false, vdr then tries to display
the message.

See cSkinDisplayReplay::SetMessage().

the unpatched vdr-1.5.16 does not contain that. Are you sure you
are using an unpatched vdr? (Sorry, could not resist ;-) )

I do have
void cSkinClassicDisplayMessage::SetMessage(eMessageType Type, const char *Text)

but this plugin does not use skins at all for its player osd.
Just cOsdProvider::NewOsd(). So I dont see how SetMessage() could 
help me.

So I omitted the parameters, big deal ;-)

You could set your OSDs "level" to something greater than 0.
Then it will be pushed into background when a higher level
OSD comes up, and restored after that.
