Problems with the source of Video Output /Video/Media Player in QML

Does the source have to be an absolute path? main.qml and myVideo.mp4 are in the same folder, and I have also added the video manually in the qrc file in QtCreator. I tried relative path, but it doesnt work (error 2: failed to load media):         MediaPlayer {             id: mediaplayer             source: "myVideo.mp4"             autoPlay: true         } It only works with absolute path.         MediaPlayer {             id: mediaplayer             source: "file:///Users/mshefiti/Developer/Qt/QtWorkspace/Workflow_Sensitive_UI/myVideo.mp4"             autoPlay: true } Also, how can I stream a video from the internet (lets say youtube)? I tried to put the youtube link, but it also doesnt work:         MediaPlayer {             id: mediaplayer             source: "https://www.youtube.com/watch?v=m2qJMbzwA3w"             autoPlay: true         } Any suggestions anyone? Thanks
