wx.media.MediaCtrl

[Blujacker]

Is possible play waw, wma, mp3 with wxPython without oppening any window? Program will be based on Tk, only playing sounds on wx.

[vegaseat]

At first blush, I would say no, since you have to assign a parent to the control widget and the parent has to be a wx frame. wx panel or such thing.

You could however write a minimum wx program and then run that from within Tkinter with execfile("My_wxplayer.py").

Hi, it's again me :) I have another question : Is possible to resize an video file like *.mpg or *.avi?? Each other format has another height and width. I need size of every video like 500,500
thanks for answers:)

[vegaseat]

I dug up some work I had done with the tkSnack module a while back, and low and behold, it does allow you to play sound files with the Tkinter GUI. At least .wav .mp3 and .au sound files. I posted an example in the Python snippets:
http://www.daniweb.com/code/snippet511.html

As far as resizing of videos goes, it should be possible in Python, I know I have done it in C++ in my younger days. I will have to check further.

It's my last topic here. Soon i go on holidays so you will have free from me:D. I looked at code snippet. There was an example of wx.medi.MediaCtrl(), You choosed file and it called function doLoadFile(path). But it doenst play now, you must press button play:(

Problem is on line 72. After load file is self.mc.Play() , but iis doesn't play. Why and how to repair it?
Thanks and have nice holiday

Hmm, I took your modified code and it works just fine. What kind of audio file did you try to load?

[Blujacker]

yes it works fine but if you load a file, it doesnt play now, you have to press button play to play the file. I need to play now after load without pressing some buttons...

[vegaseat]

In my test it played right after the file load. You have to press the button only if you want to play it again.

no, thats not possible, it doesnt work fine. Maybe you changed code, reply here your code pls:D

sorry, but it doesnt work,(it doesnt play right after load!) slider work not to:(( I will try it later, and sory and thanks

[bumsfeld]

I tried it on my Windows XP and it works as Vega says. What operating system you have? The control uses different audio drivers for each OS.

Does it play sound at all?

Aloha:cool:

The wx.media.EVT_MEDIA_LOADED event needs to be captured:

    self.Bind(wx.media.EVT_MEDIA_LOADED,self.OnPlay)

 def OnPlay(self,event):
    if self.mpState == mpPLAYING:
      self.mp.Pause()
      self.mpState = mpPAUSED
      self.Msg('Paused: %s' % self.ActiveFile)
    else:
      self.slider.SetMax(self.mp.Length())
      self.mp.Play()
      self.mpState = mpPLAYING
      self.Msg('Playing %s' % self.ActiveFile)

You'll want to manage your own player state as well, since GetState() is not reliable.

[karenmaye]

Hi, I tried using this code because I would like to play a video file using wxPython. But the video does not show up at all, I only hear the audio. What seems to be the problem? I am using Python 2.6 and wxPython 2.6.

[lllllIllIlllI]

Python 2.6 has known issues with wxPython, i would reccomend that you download 2.5
