If you go to plone4artists.org now it will redirect you to dev.plone4artists.org
.
Brayton- it would be great if you could contribute your code to a
branch in the collective and then we will review it at the video
sprint in a few weeks in Budapest.

Espen,
You do understand me correctly and I have this mostly working as you
describe. It works for .mov files, though I haven't been
successful with
a flash video yet - I still get the solid black background with play
arrow. I'm going to keep working on that.
I'm happy to share with p4a, though I haven't received anything
but a
503 error at plone4artists.org for the last few weeks. Who should
I get
in touch with to share it?
Thanks,
Brayton

If I understand this right and you got this to work:
1) Add a "p4video-file" to plone
2) The first frame of the image shows as the video/image.
I am pretty sure the people behind p4artists would like that
code....

to write the captured image back into Plone, but I think I have

Here is the code I used (for future Googlers):
context = aq_inner(file)
movie_data = context.get_data()
movie_id, movie_name = tempfile.mkstemp('.mov',text=False)
image_id, image_name = tempfile.mkstemp('jpg', text=False)
output_id, output_name = tempfile.mkstemp()
wfile = open(movie_name, 'wb')
wfile.write(movie_data)
wfile.close()
args = "ffmpeg -i %s -ss 1 -an -vframes 1 -f image2 %s" %
(movie_name, image_name)
p = sub.Popen(args, shell=True, stdin=sub.PIPE,
stdout=output_name,
stderr=sub.STDOUT)

Hi Brayton,
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()))

I'm trying to extend P4A Video to automatically generate the

Right now I'm running into trouble capturing an image from a
video file
once it's stored in Plone. I've tried calling ffmpeg as a
subprocess,
but I get an I/O error (see below):
image = subprocess.Popen('ffmpeg -i moviefile -ss 1 -an -
vframes 1
-f image2 thumb%2d.jpg', shell=True, stdin=subprocess.PIPE,
stdout=subprocess.PIPE, stderr=subprocess.STDOUT,

print image.stdout.read()

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

To call it with subprocess :
- use mkstemp python module to create a temp file
- write the raw data inside it
- do the subprocess on that new tempfile
- don't forget to delete the temp file
- write the image inside your image field.
