p4a-video uses the File-content-type, which again uses OFS.File as
content-class. If you want to access the raw-data use:
atfileobject.getFile().data
or
str(atfileobject.getFile())
If you need a file-like object, you have to do:
stream = StringIO(str(atfileobject.getFile()))

Right now I'm running into trouble capturing an image from a video file

moviefile: I/O error occured
Usually that means that input file is truncated and/or corrupted.
I've tried doing this where 'moviefile' is an <ATFile at
/Plone/Members/brayt/jumping2.mov> object, a <p4a.video _ATCTFileVideo>
object (applying the IVideo interface to the ATFile), and even the
binary data (passed by moviefile.getData()). Each case gives me the same
error.
I suspect this is because ffmpeg expects to receive certain file types,
and Plone files are somehow wrapped so they aren't recognized. I guess
my question may boil down to how do I access (and do something useful
with) the data in a file that's not normally read by Plone? I suspect
that the indexing of PDFs behaves similarly to what I'm hoping to do,
but I haven't quite figured out how that works.
Any help would be greatly appreciated!
Thanks much,
Brayton
