Usage instructions

[GoogleCodeExporter]

Hi,

I'm just having some trouble getting this project to work, sorry I'm also 
inexperienced with Python...

I execute:

ff = FFDocument("movie.flv")
ffresult = ff.resize("50%").ltrim(10).resample(120)

First I receive an error about unknown clone() on line 63 file.py. I have 
changed this to __clone__() and now it works.

But then, how do I execute the conversion?

I tried:

fm = FFmpeg("ffmpeg")
fm.render(ffresult, "out.flv")

But I have this error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.5/site-packages/wffmpeg/ffbase.py", line 40, in 
render
    for i in range(0, len(effectchain)):
AttributeError: FFDocument instance has no attribute '__len__'

..can you help me? Maybe a basic tutorial would be great :-D

fm.render(ffresult, "out.flv")

should be

fm.render([ffresult], "out.flv")

quoting the above example.
render takes an array of transformations.  even then, the code is flawed and 
will not
work.  i've submitted one patch, when i've time i will submit others, or rather 
fork
the project alltogether. 
whilst its an interesting idea, the current code is too flawed for use, i'd 
rather
stick to creating cli strings for ffmpeg for the time being, which is pretty 
much
what the wrapper does.
plus, by chaining different transformations, instead of compiling the different
effects in one execution of ffmpeg, it calls ffmpeg once for every 
transformation,
leading to extremely long times of encoding.
nonetheless its a great idea.
