Default (Moode) cover to display on 'mpc stop'

[Phaet]

Hi, this is not an issue or a bug. I just want to ask a question:

I extended the lirc config so that I can use my RC, mainly to select radio stations from a dedicated playlist by means of the number keys.

I also want to use the stop button (■) mapping it to 'mpc stop'. But then the display still shows the logo of the previously played station.

Could you please give me a hint, where to modify your lcd code to show sort of idle logo?

Thanks in advance.

After giving it a quick thought, I think I would do something like that on a running rdmlcd :

• Create a png file with 320 pixels width x 240 pixels height. Draw whatever you want in there.
• Name the png file iddleimage.png
• Use FTP to upload iddleimage.png into /usr/local/etc/rdmlcd/iddleimage.png
• Add the following blocks to function processChanges in /usr/local/etc/rdmlcd/utils/moodelistener.js :

moode_listener.prototype.processChanges = function(key,data){ 

    if( ["title", "artist", "album"].includes(key) ){
        this.formatMainString();
        this.emit( "trackChange", this.formatedMainString );
        if(this.state === "play") this.resetIdleTimeout(); // sinon les webradios sortent l'écran de veille 
    }
    else if(key === "state"){
+       if(data === "stop"){
+           this.data.coverurl = "./iddleimage.png";    // set the iddle default image as the current cover
+           this.emit("coverChange", "./iddleimage.png");   // print the default image on the display
+           this.formatedMainString = "";           // empty the text field for trackname / artist / album 
+           this.emit( "trackChange", "" );         // print the empty text field on the display
+       }
+       else{
+           this.formatMainString();                 // regenerate text field for trackname / artist / album 
+           this.emit( "trackChange", this.formatedMainString );     // print the non-empty text field for trackname / artist / album on the display
+       }
        this.state = data;
        this.resetIdleTimeout();
        this.emit( "stateChange", data );
    }
    else if( ["song_percent", "time", "elapsed"].includes(key)){
        this.seekFormat();
        this.emit( "seekChange", this.formatedSeek );
    }
    else if(key === "bitrate"){
        this.emit( "bitRateChange", data );
        this.emit( "line2", "Bit Rate : " + data );
    }
    else if(key === "volume"){
        this.resetIdleTimeout();
        this.emit( "volumeChange", data );
    }
    else if(key === "audio_sample_rate"){
        this.emit( "sampleRateChange", data );
        this.emit( "line0", "Sample Rate : " + data );
    }
    else if(key === "audio_sample_depth"){
        this.emit( "sampleDepthChange", data );
        this.emit( "line1", "Sample Depth : " + data );
    }
    else if(key === "coverurl"){
+       if(this.data.state === "stop"){                 
+           this.data.coverurl = "./iddleimage.png";            // if playback is stopped, cancel the cover update and reset the default iddle image as current cover
+           return;
+       }
        if(data === 'sudo: /var/www/util/upnp_albumart.py: command not found'){
            this.getFallbackCoverFromMeta();
            return;
        }

        if ( /http:\/\//.test(data) ){
            this.emit( "coverChange",data );
            return;
        }
        if(data[0] !== "/") data = "/"+data;
        this.emit( "coverChange","http://"+this.host+data  );
    }
    else if(key === "file"){
        this.emit( "file", data );
    }
    else if(key === "audio_channels"){
        this.emit( "channelsChange", data );
        this.emit( "line3", "Channels : " + data );
    }
    else if(key === "encoded"){
        let pdata = data.replace(/audio/gi, "");
        this.emit( "encodingChange", pdata );
        this.emit( "line4", "Track Type : " + pdata );
    }
    else if(key === "song"){
        let pdata = parseInt(data)+1;
        this.emit( "songIdChange", pdata );
        this.emit( "line5", "Playlist : " + pdata + " / " + this.data.playlistlength );
    }
    else if(key === "repeat"){
        this.emit( "repeatChange", data );
        this.emit( "line6", "Repeat : " + data );
    }
};

(don't forget to remove the "+" on line starts if you copy-paste)

Obviously I don't have all the possible scenarios in mind and doing this may possibly cause weird behavior with external music services. But that should be a good start.

and of course sudo systemctl restart rdmlcd after you are done.

Hey great. Thanks for the speed of light reply. This is exactly what I am looking for and should do the trick. I'll drop a note as soon as it is working.

Works smoothly :smiley: Thanks a lot!
