Yeah, I'm basically figuring that the bounty would be for someone who
already has done most of what I am looking for.<br>
<br>
I don't need to use VideoCapture necessarily. That just happens to be
what we currently have implemented, and it serves as an example of how
I can display video given a frame buffer. The idea is that
VideoCapture might be replaced by something else that can write to a
frame buffer, so the developer doesn't need to worry about the user
interface or video display when implementing the items on my list. I
use VideoCapture because it is a python library.<br>
<br>
Why would webcams be difficult? Sure they are platform dependent, but
they just put data in a frame buffer, so maybe 2 or 3 relevant
functions in the API should do it.<br>
<br>
BTW, Are there binaries for python bindings for Windows? I simply
don't have time to build it myself unless I know I am going to use it,
and I won't know that until I see it working on Windows in wxPython.<br>

First thing you would need to get your frame buffer form the
VideoCapture is a gstreamer plugin that can interface with
VideoCapture... <br>
<br>
And if it doesn't exists... create one, which means you will have to
compile gstreamer on windows wich is not trivial...
<br>
<br>
All that in 4 days , you would need someone who already has a
gstreamer code base that can compile in windows and knows your
VideoCapture lib...<br>
<br>
But other then that gstreamer seems a good choice for your
application. <br>
<br>
The difficult part I guess will be the webcam access on the different
platforms as it's driver dependant... I had a lot of troubles with
webcams on linux... but that beeing said it's not related to
gstreamer. <br>
<br>
<br>
Good Luck! :)<br>

<div bgcolor="#ffffff" text="#000000">BTW, if it would help, I can
post a $2000 bounty on a wxPython
application that demonstrates the functionality listed below by May 1,
2007. The result would be open source. If you are interested, I can
provide you with a simple wxPython demo application that displays video
from a frame buffer connected to VideoCapture (a Windows-only webcam
capture library). My wxPython demo app could easily be made to display
any flat RGB frame buffer, so you don't need to worry about GUI
development. If that schedule is a bit tight, we can negotiate a
little.<br>
<br>
Anyone interested?<br>

<br>
Is anyone working on a multi-platform python egg? If gstreamer happens
to be what I am looking for, I might be willing to contribute
development of the egg installer if nobody is doing that yet.<br>
<br>
How does gstreamer compare with kamaelia?<br>
<br>
The development seems to be Linux-centric, which is definitely better
than Windoze-centric, but I am wondering if anyone is successfully
using gstreamer to develop applications that run on Windows too.<br>
<br>
Thanks a bunch,<br>
