Unable to run video with QT Mediaplayer in one of my computers

Shahar

I am using 2 computers with the same aplication to show videos with QT Mediaplayer.
One of the computers run the video properly while the other one just show a white screen.

I checked and the QT Mediaplayer in both computers are the same.
This is the code I am runing:

def put_video_in_layout(self, color, video_path):
print("Input video in layout")
Video_url1 = QUrl.fromLocalFile(video_path)
print("!!!!!!!!!!!!!!!")
print("Video path:", video_path)
print("File exists:", os.path.exists(video_path))

    video_widget = QVideoWidget()
    if color == "w":
        video_widget.setStyleSheet("background-color: rgb(255, 255, 255); border-radius: 10px")
    else:
        video_widget.setStyleSheet("background-color: rgb(77, 70, 210); border-radius: 10px")
    video_widget.setFixedSize(380, 500)
    video_widget.setSizePolicy(QSizePolicy.Fixed, QSizePolicy.Fixed)
    video_widget.setAspectRatioMode(Qt.KeepAspectRatio)

    media_player = QMediaPlayer(None, QMediaPlayer.VideoSurface)
    media_player.setVideoOutput(video_widget)
    video_content = QMediaContent(Video_url1)
    media_player.setMedia(video_content)

    # Debugging output
    print("Video widget created:", video_widget)
    print("Media player created:", media_player)
    print("Media content set:", video_content.isNull())

    # Connect signals for debugging
    def handle_media_status(status):
        print("Media status changed:", status)
        if status == QMediaPlayer.LoadedMedia:
            print("Media loaded successfully")

    def handle_error(error):
        print("Media player error:", error, media_player.errorString())

    media_player.mediaStatusChanged.connect(handle_media_status)
    media_player.error.connect(handle_error)

I will apriciate any help,
Thanks !!

Hi and welcome to devnet,

Are you using PySide2, PySide6, PyQt5, PyQt6 ?
Which version ?
On which OS ?
What kind of video is that ? Container format ? Video codec ? Audio codec ?
