ProppFrexx ONAIR User-Forum

Hi Bernd,

I'm new at this forum. I have a question. Is it possible in PF that the album cover of the currently playing track is send along with the song info, so that it will be displayed in a webplayer on my website? e.g. like this http://www.rockfiles.nl

There is already a v4.0.4.19-beta out (use "Check for Beta-Versions..." to update).
This version contains a new control command called: EXEC_WRITE_JPEG_FILE, which writes any track's album art image to a file.
Parameters: filename[|from[|size]]
Note: The filename should denote the full path to a .jpg file; what can be '0'=current track (default), '1'=next track, 'A'=current player A, 'B'=current player B, 'C'=current player C, 'D'=current player D; size defined the quadratic with/height (default is 200).
Example:

Yes, but that is not as easy as you think it might be

ProppFrexx contains several macros which can be used to 'send' a cover art image:
- ${albumart}
- ${cpltrackalbumartcurrent}
- ${cpltrackalbumartnext}
- ${cpltrackalbumarta}
- ${cpltrackalbumartb}
- ${cpltrackalbumartc}
- ${cpltrackalbumartd}
- ${plstrackalbumartcurrent}
- ${plstrackalbumartnext}

These macros can be used exactly like any other existing macros which you might use to transmit the song title, artist etc. to your web-site.
E.g. via the following control-commands:
- EXEC_SEND_HTTP_GET
- EXEC_SEND_HTTP_POST
- EXEC_WRITE_PLAYLISTFILE (see here for details http://www.proppfrexx.radio42.com/myBB/ ... php?tid=72)

Note, that above album art macros resolve the cover art image of an audio track (if existing) to a Base64 encoded string containing the binary image data of a Jpeg image.
This means:
- ProppFrexx reads any existing track image
- converts that to a Jpeg image of size 200x200
- uses that converted image and used a standard base64 encoder to convert that to a string

On your web-site (when receiving/reading that base64 image string) you must:
- decode that received string back to binary data (e.g. via the PHP 'base64_decode' function)
- use that decoded binary data to create the image on your web-site
- use the 'image/jpeg' mime type for that!

Thank you for your answer. I will try to fix it.

Hi Bernd,
I,m still trying to fix my problem. I already found, how to get the song info in my webplayer. But in wich command do I fill in this info:
- ${albumart}
- ${cpltrackalbumartcurrent}
- ${cpltrackalbumartnext}
- ${cpltrackalbumarta}
- ${cpltrackalbumartb}
- ${cpltrackalbumartc}
- ${cpltrackalbumartd}
- ${plstrackalbumartcurrent}
- ${plstrackalbumartnext}

Could you help me along with this?

Best Regards!

The above macros can be used with any control-command.
As said above...
E.g. via the following control-commands:
- EXEC_SEND_HTTP_GET
- EXEC_SEND_HTTP_POST
- EXEC_WRITE_PLAYLISTFILE (see here for details http://www.proppfrexx.radio42.com/myBB/ ... php?tid=72)

And as said above, these macros are resolved to a Base64 encoded string containing the binary image data of a Jpeg image.
This means:
- ProppFrexx reads any existing track image
- converts that to a Jpeg image of size 200x200
- uses that converted image and used a standard base64 encoder to convert that to a string

As a result the macro will resolve to a base64 encoded string containing the raw image data!

On your web-site (when receiving/reading that base64 image string) you must:
- decode that received string back to binary data (e.g. via the PHP 'base64_decode' function)
- use that decoded binary data to create the image on your web-site
- use the 'image/jpeg' mime type for that!

So I am not sure what info you are actually missing.

Maybe this will help you.

<?php
echo "<img src=data:image/jpg;base64,${currentalbumart} width='200' height='200' border='0' title='${currenttrackname}' >";
?>

Thanks for your answer! What I actually need to know is where excactly in PF do I fill in these commands.. I know that it's needs to be doen in de event/command section. But what are my next actions then?
Maybe someone could help me out with this..

Thank you Bernd,

But when I'm there, what's my next action?
I put an attachment with this message, so you can see my current situation.

Not sure what more you are looking for.
When you placed those two commands e.g. with the "Streaming.OnSongTitleChanged" event and they are working fine...then you might have a file called 'test.html' on your web-site?
Is that working?
If not, what happens, if you open the file C:\Test\test.html locally within your internet browser?
