Running video in Python using VLC and PyQt doesn't start - python

I'm trying to get a video to play in a frame in PyQt through VLC, I followed a similar question on here to get the sample code to use:
class VideoPlayer(QMainWindow):
def __init__(self, parent, inputPath):
super(VideoPlayer, self).__init__(parent)
self.setWindowTitle("Media Player")
# creating a basic vlc instance
self.instance = vlc.Instance()
self.mediaplayer = self.instance.media_player_new()
##########video frame
self.videoframe = QFrame(
frameShape=QFrame.Box, frameShadow=QFrame.Raised
)
if sys.platform.startswith("linux"): # for Linux using the X Server
self.mediaplayer.set_xwindow(self.videoframe.winId())
elif sys.platform == "win32": # for Windows
self.mediaplayer.set_hwnd(self.videoframe.winId())
elif sys.platform == "darwin": # for MacOS
self.mediaplayer.set_nsobject(self.videoframe.winId())
central_widget = QWidget()
self.setCentralWidget(central_widget)
lay = QVBoxLayout(central_widget)
lay.addWidget(self.videoframe)
filename = inputPath
media = self.instance.media_new(filename)
self.mediaplayer.set_media(media)
self.mediaplayer.play()
Trying to run this just gives me these errors whenever I start it up though:
[0c92dc18] mmdevice audio output error: cannot initialize COM (error 0x80010106)
[0ef89108] mmdevice audio output error: cannot initialize COM (error 0x80010106)

[0f07c670] main video output error: video output creation failed
[0ef90360] main decoder error: failed to create video output
If I run the video without using PyQt, just as:
Instance = vlc.Instance()
player = Instance.media_player_new()
Media = Instance.media_new(inputPath)
player.set_media(Media)
player.play()
time.sleep(5) # Or however long you expect it to take to open vlc
while player.is_playing():
time.sleep(1)
if 0xFF == ord("q"):
player.stop()
player.stop()
It works fine. Can anyone point me in the direction of what I might be doing wrong here?

I have tried to recreate the issue and reached to the solution below:

VLC causes buffer when embedded in Python Tkinter Frame

I have been working on a music player app that uses VLC to play songs directly from the internet and has features like seeking and a progress bar. But as the normal tkinter progress bar looks kinda old so I used customtkinter.CTkSlider widget but using this causes buffering. The song plays smoothly on using Tk.Scale.

Python-vlc error: HTTP connection failure

I'm trying to play an online video using python-vlc library.
First, I was using a simple version of the player to test it out:
import vlc
#example url
url="https://player.vimeo.com/external/363536021.hd.mp4?s=6f6e87d86a49149479ebdab6c8bc421aa89f327c&profile_id=175&oauth2_token_id=57447761"
player = vlc.Instance().media_player_new()
player.set_media(vlc.Instance().media_new(url))
player.play()

The problem is that as soon as you start playing the video it is not available since the download is not immediate but with your code you try to update the position. The solution is to update is to get the position after it started playing:

PyQt5 Cant link slider to the playing audio in my mp3 player

I am making an Mp3 Player, and I am almost done, the only thing left is the time slider.
I managed to make the slider so that it can change the position/time of the audio, but I want the vice-versa now, the slider to be moved by the audio progress.
(Ignore this pls, they are asking for more details but I got none other to give, thanks)

Thanks in advance!
The slider has a setValue to set the slider position (0-1). To update the slider, add a timer to the app.
Update your code with the following changes:
class UiMainWindow:
def __init__(self, main_window):
..........
# timer to update slide bar
timer = QTimer(self.main_window)
timer.timeout.connect(self.time_hit)
timer.start(500) # 1/2 second
def time_hit(self):
if self.player.is_playing():
self.time_slider.setValue(self.player.get_position()*10000) # update slide bar

How to draw/animate transparent images/objects over a video in PyQt5?

I created a media player application using python-vlc and PyQt5, quite similar to this qtvlc code.
A minimal reproducible code is shown as follows:
class Player(QMainWindow):
"""A simple Media Player using VLC and Qt
"""
def __init__(self, master=None):
QMainWindow.__init__(self, master)
self.setWindowTitle("Media Player")
# creating a basic vlc instance
self.instance = vlc.Instance()
# creating an empty vlc media player
self.mediaplayer = self.instance.media_player_new()
self.createUI()
self.isPaused = False
def createUI(self):
"""Set up the user interface, signals & slots
"""
self.widget = QWidget(self)
self.setCentralWidget(self.widget)
self.videoframe = QFrame()
self.videoframe.setAutoFillBackground(True)
pixmap = QtGui.QPixmap()
pixmap.load("path to transparent_image.png")
self.my_label = QLabel(self)
self.my_label.setPixmap(pixmap)
self.my_label.setGeometry(300, 250, 100, 100)
self.my_label.setFrameStyle(QFrame.NoFrame)
self.my_label.setAttribute(Qt.WA_TranslucentBackground)
self.vboxlayout = QVBoxLayout()
self.vboxlayout.addWidget(self.videoframe)
self.widget.setLayout(self.vboxlayout)
self.media = self.instance.media_new("path to video file")
# put the media in the media player
self.mediaplayer.set_media(self.media)
# the media player has to be 'connected' to the QFrame
# (otherwise a video would be displayed in it's own window)
# this is platform specific!
# you have to give the id of the QFrame (or similar object) to
# vlc, different platforms have different functions for this
if sys.platform.startswith('linux'): # for Linux using the X Server
self.mediaplayer.set_xwindow(self.videoframe.winId())
elif sys.platform == "win32": # for Windows
self.mediaplayer.set_hwnd(self.videoframe.winId())
elif sys.platform == "darwin": # for MacOS
self.mediaplayer.set_nsobject(self.videoframe.winId())
self.mediaplayer.play()
if __name__ == "__main__":
app = QApplication(sys.argv)
player = Player()
player.show()
player.resize(640, 480)
sys.exit(app.exec_())
Once I run the code, I can see that the transparent image is drawn on top of the video but the image instead of showing the background video through it continues to show the portion of the QFrame as its background. Can anyone help me with getting around this issue?
