Erik,

Wow, that’s really ambitious.

I write an open source app using wxPython for academic video analysis called Transana, which you might find interesting to look at. The web site is at http://www.transana.org and the source code is at http://sourceforge.net/projects/transana. You might particularly want to look at video_player.py, which (when run as a stand-alone) will play most videos that can be displayed in Windows Media Player or QuickTime on Windows or just QuickTime on the Mac, or gstreamer Linux. It’s based on wx.MediaCtrl.

If you make good progress on your app, I’d be really interested in seeing your code. Some day I’d love to add the capacity to take the virtual clips I create and manufacture a real stand-alone video file from them.

Re: [wxPython-users] pyeMedia

David,
I am trying to make a video pre-edit program for web presentation.
So the operator:
loads in a bunch of video clips,(AVI or Mpeg2 or Mpeg4)
looks at clips and
decides which ones to dock the head or tail of( cause he started to early and/or forgot to stop the camera)
all clips are then combined/compressed into .flv or .swf format and ftp-ed to professional editors who will publish it on the web

So now I am also trying wxMedia, but I am still so clumsy with Python(wx - boa) that I can barely discern bugs from my own mistakes!!!

Erik,

If I remember right, you have to build your own binaries from the source. 

What is it you are trying to do?  There may be better ways of doing it than pyMedia, which is buggy if I remember right and a bit stale by now.  It's been a year and a half since they updated their source code.

I played with PyMedia a year or so ago, but gave it up for wxMediaCtrl, which met my video needs better. That was obviously several wx versions ago. I also found PyMedia to be too slow to do some audio extraction I needed.

HAs anybody played with this video/audio lib? I am using Active Python
2.5 and wxPython 2.8.7.1
I had a very hard time to find a Pyemedia windows binary to match. However none of the examples seem to work (or better they don't do
anything and stop without leaving any trace or error log).
Any suggestions?
Cheers

Sorry, I don’t know what it could be. The whole indenting thing is pretty basic to Python, and clearly there’s something about your indents that Python’s not happy with.

But literally, I cut and pasted the code from your earlier e-mail into an IDLE window, fixed the “return True” line which had lost its indent, changed the video file name, and saved the file as a text file with a .py extension. Then I ran it from the command prompt. I know (from experience) that “It Works For Me” isn’t very helpful.

It looks like you’re pasting directly into a python shell rather than creating a file and running it, maybe. Is that what the ‘File “”’ part of the error refers to? I can’t tell. It looks like something about your environment, anyway, and the way you’re trying to run code, but not something about the code itself. Get a “Hello World” program running from a file and expand from there, I guess.

FWIW, the file is attached.
