Can't write a movie with default codec

[gvx]

It seems I can only use the 'raw' encoding.

>>> video.to_movie("myHolidays_edited.avi",fps=24)
Making file myHolidays_edited.avi ...
Rendering video :
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "moviepy/VideoClip.py", line 323, in to_movie
    codec = 0 if (codec=='raw') else cv2.VideoWriter_fourcc(*codec)
AttributeError: 'module' object has no attribute 'VideoWriter_fourcc'
>>> video.to_movie("myHolidays_edited.avi",fps=24,codec='raw')
Making file myHolidays_edited.avi ...
Rendering video : 0%  10%  20%  30%  40%  50%  60%  70%  80%  90%  done !
>>> 

I have cv2 version 2.4.6.1, if that matters.

Exactly ! I swear, this little "fourcc" function has had four different names in the last four releases of opencv, and they are the reason that I request recent versions... I think I will make a hack for the program try several syntaxes, so that everyone can use it, whatever the version.

Do you have cv2.cv.FOURCC ?

[gvx]

>>> cv2.cv.FOURCC
<built-in function FOURCC>

Yup.

[Zulko]

Ok, I just intalled 2.4.6.1 and from what I see the program should break also when you load a movie.
Have you tried something like this ?

from moviepy import *
MovieClip('foo.avi').subclip(0,1).preview()

[Zulko]

Ok, I may or may not have patched all that (added an horrible hack in the beginning of VideoClip.py that looks for the constant names, since they vary between versions). Now it seems to work fine with 2.4.6.1 on my computer.

You were right, when I tried to do MovieClip('something.avi'), it gave:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "moviepy/VideoClip.py", line 734, in __init__
    self.fps = self.cap.get(cv2.CAP_PROP_FPS)
AttributeError: 'module' object has no attribute 'CAP_PROP_FPS'

Redownloading solved both writing and reading non-raw clips for me, so this seems to be solved.
