Broadcast OSD "on the fly" with RPN functions

[fazer]

Hi to all,

I wrote a new message in the following post :
viewtopic.php?p=89519#89519

but maybe would it be more suitable to expose my problem here...

What I need is to display some messages "on the fly" during a show (to implement some EPG in a streamed video application).
I control VLC thru his http interface with the help of a html page I specially designed with VLC tags (actually, I use RPN functions for that).
The problem is that 'marq-marquee' sub-filter (module marq) doesn't seem to work via RPN functions. I tried many differents approaches (vlc_set_var, ...) with no success. The only way I could make it work was with RC interface but I want to use http interface for some reason...

Does someone have an idea how to make it work with RPN functions ?
(BTW, I got the same problems described in the above post in the same situations.)

Thanks for your help.

You've probably found another answer for this by now ... but ...

The "get" and "set" macro functions should be able to do what you want with marquees.

When I did this command ....

GET: <vlc id="get" param1="marq-marquee" param2="string" />

I got the default "VLC" marquee

I haven't tried it but ...

<vlc id="set" param1="marq-marquee" param2="string" />

Should work if you feed "marq-marquee=some_url_encoded_text" as one of your parameters in the url request.

This is the macro.c way ... I haven't figured out the rpn.c way using vlc_var_* ...

The object store seems to be a bottom-less pit that variables don't like coming out of. I've walked through source for hours and still haven't got a clue how to figure out what's what when it comes to access via vlc_var_*.
