You check the wiki? I haven't, but I imagine it would be there. I wanna follow this I find it interesting.

You could name it "controlpanel.swf" and it would override the cp with or without a connection until you pull the usb stick out, am i right? I really don't know.

I've added this page on how to control BTPlay from Flash - note that this only works from a local movie, not a widget.

These are the calls that the Control Panel uses to play music.

You might also find this snippet of Actionscript handy for the enumeration of files on the USB drive.

i played around with the file browser snippet from Duane, but couldnt get it to work.

The big problem is, that it does not run on my xp machine - maybe i am to stupid, or
maybe its cause of the missing flash lite 3 runtime environment.

And this means the whole thing is very hard to debug, cause the chumby is then a black box.
So it will take time, until i got something to work...

Duane, thanks for the hint - i already got the trace statements. Testing is ok with an ssh/sftp connection (although i dont know what i have to kill to stop the controlpanel from respawning).

Nevertheless it isnt working:

The path in your snippet is "/mnt/usb", but in the controlpanel it is "//mnt/usb/" and only with this path i get stream 1 opened.
I copied now the essential parts of the controlpanel, to try exactly the same code in my environment (Flash CS3), but it isnt working either...

This is the output:

great, that was the problem!
i really wonder that there is no compilation error with 2 missing functions...and also no runtime error

so lets see whats next

Duane, i got it running, but there is one thing missing:

how can i create an m3u file from flash?
or how can i feed the playlist into the pipe of btplay?

i've found the function

_putFile = ASNative(5, 51);

but it isnt working somehow....

Please help!

_AddToPlaylist = ASnative(5,149);

is not working.
I tried:

_AddToPlaylist("/mnt/usb/Candy.mp3");

and i got:

2008-04-02 23:49:46 TRACE: //mnt/usb/Candy.mp3
2008-04-02 23:49:46 BtplayPlaylist: required argument(s) missing

Nevermind, i will try keep the playlist on my side, so i can better control shuffle and repeat...
Where can i post the prototype?

Ah, sorry, I had an error on that page, which I've corrected.  This call requires the first parameter to be the mimetype of the files, which mean you need at least two parameters.

@Beastlykings:
you can try the prototype of my mp3 player:
http://rapidshare.com/files/105162743/RxPlayer.rar

shuffle and repeat are broken. use at own risk.
if you still want to test, then just extract the archive to a usb stick with mp3 files on it.

Cool!! Works Well. Will Is there ff and rewind? Much better than the My Music files function!

It plays a few songs and then starts from the first again....am I doing something wrong?
Thanks
