How to access Metadata from audio files

[p3c0]

@Nisha_R

console.log(a.title)

Shouldn't that be a.metaData.title ?

[Nisha_R]

Thank you @p3c0
still the output remains undefined!!

[p3c0]

@Nisha_R Are you sure the media file contains metadata ?
I just tried this example and in onPressed, console.log(playMusic.metaData.title) printed the title as expected.

[Nisha_R]

@p3c0 i am sure the song contains the metadata because i have edited it online.
could you please share the code you have worked on?

[p3c0]

@Nisha_R Thats strange. Try following:

import QtQuick 2.6
import QtMultimedia 5.6

Item {
    width: 400
    height: 400

    Text {
         text: "Click Me!";
         font.pointSize: 24;
         width: 150; height: 50;

         MediaPlayer {
             id: playMusic
             source: "MySong.mp3"
         }
         MouseArea {
             id: playArea
             anchors.fill: parent
             onPressed:  {
                 playMusic.play()
                 console.log(playMusic.metaData.title)
                 console.log(playMusic.metaData.albumTitle)
                 console.log(playMusic.metaData.genre)
                 console.log(playMusic.metaData.year)
             }
         }
     }
}

@p3c0 thank you.

[Nisha_R]

@p3c0 Thank you again,
i have got it right when i set the relative path for the mp3 file i,e the source , but when i try to access the mp3 files from resources it is still undefined.

[p3c0]

@Nisha_R How did you set the source ?

[Nisha_R]

@p3c0 ,
i had initially dumped the mp3 files in resources folder and tried to access those in my code.

[p3c0]

@Nisha_R No. I meant to say the source url. What does it look like? Can you post it ? Checking if the url from resource is correct.

[Nisha_R]

@p3c0 this is what i have given.
Audio {
id: playMusic
source: "qrc:/music/2.mp3;"
}
music being the folder in resources.

[p3c0]

@Nisha_R Why the extra semicolon at the end in source ?
Does the Application Output show any errors ?

[Nisha_R]

@p3c0 there is no error with respect to the semicolon .
setting its path with respect to resources shows undefined, but when its relative path is set the metadata is displayed.

[p3c0]

@Nisha_R Did you try removing the semicolon ?
Also are you sure the file is present at the same location in the resource ?

[Nisha_R]

@p3c0
yes , i have tried, still undefined.

[p3c0]

@Nisha_R Does it play from resources ? Can you post a complete minimal example with this Audio element here?

[Nisha_R]

@p3c0 okay that will be helpful.
