Error: Cannot assign [undefined] to QUrl
-
Hi all ,
i am developing a music player module for car HMI in QML, for that i am importing QtMultiMedia 5.0 for the functionality of music. i am using folderListModel to get the songs which are there in my project songs folder. The problem i am facing is, whenever i try to play the songs using my application i get the following error:Error: Cannot assign [undefined] to QUrl
on this line mediaplayer.source= items.get(index,"filePath")can anyone please tell me what is wrong in the code? thanks
my code:

@sierdzio i tried this with a small example, what i am doing is on a click of button i am trying to play the song. here i am not getting any error but i didn't get output also, on click of button nothing happens.. i tried printing using console, here is the minimal code which i am trying...

No, I mean print the items.
console.log("Items:" + items) mediaplayer.source=items.get(index,"filePath"); console.log("before playing the song") mediaplayer.play();Looks like something is bad in your env, too, see these lines:

Almost :-)
for (var j=0; j<items.count;j++){ console.log("item:"+ items.get(index,"filePath")) }Maybe that will help us pinpoint the issue.
@sierdzio Hi, i tried printing those items, but i am getting the same error again (Error: Cannot assign [undefined] to QUrl), also when i try to print those items, i am not able to find the auto get method for items(i.e items.get() method) and it is not entering the for loop.
what can be the possible solution? thanks -
Please try:
- print items.count and items.get(0, "filePath")
- rewrite items to be a normal QML component and not a property (see example code in the docs) and see if it works
- make sure the path is OK :-)
print items.count and items.get(0, "filePath")
output:
qml: items count >> 0
qml: items at 0 position >> undefinedrewrite items to be a normal QML component and not a property (see example code in the docs) and see if it works
i made the following changes, pls rectify if there is any mistake
FolderListModel{ id: items folder: "/home/ubuntu/Documents/Sample_Examples_Qt_Qml/DummyMusicPlayer/Songs" nameFilters: ["*.mp3"] }after making changes i am getting the following output:

OK, so now at least we know this:
- issue is not related to QtMultimedia
- issue is with FolderListModel
- "Cannot assign [undefined]" is there, because items is empty (no .mp3 files are detected in Songs folder)
Try using URL instead of path:
folder: "file:///home/ubuntu/Documents/Sample_Examples_Qt_Qml/DummyMusicPlayer/Songs"Relative and absolute paths should work, but apparently something fails here. Also, of course, please make sure there are some MP3s in that dir.

Nice, I'm glad to hear that problem is solved.

I'm not familiar with QtMultimedia, I can't help here unfortunately. My first guesses are:
- check if you have gstreamer 0.1 installed
- check if you have mp3 codecs installed (mp3lame or something)
- check some QtMultimedia examples in Qt Creator - does the sound work there?

Thanks for the information,
But previously i had tried to play songs using this and it was working fine, i found out that when i directly give source in the media player and play it is working fine the song is playing, but when i give the folderlistmodel path using the get method it is not working.
also i tried to print the path, when i give the direct source path, the path printed is the URL path but when it takes through the folderlistmodel, it is the normal pathi.e Direct source path with song if i give, the path set is :
"file:///home/ubuntu/Documents/Sample_Examples_Qt_Qml/DummyMusicPlayer/Songs/David Guetta - Love Don't Let Me Go (Memorax Remix) [FREE].mp3"and through folderlistmodel with the index, the path set is :
"/home/ubuntu/Documents/Sample_Examples_Qt_Qml/DummyMusicPlayer/Songs/David Guetta - Love Don't Let Me Go (Memorax Remix) [FREE].mp3"Can anyone please suggest the possible solution.
Thanks -
Cool, good to hear that :) Please mark the topic as solved, too.
