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. 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. 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.

I had a lot of troubles with webcams on linux...  but that beeing said it's not related to gstreamer. Good Luck! :) <div>On 4/25/07, Ken Seehart <<a href="mailto:ken@seehart.com">ken@seehart.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <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. Anyone interested? - Ken Seehart Ken Seehart wrote: <blockquote cite="http://mid462FA2BC.8090303@seehart.com" type="cite"> What I need : - multi-platform (Linux, Windows, Mac OSX) - python bindings - streaming download from our server to our client (I need to develop both the client and the server) - simple audio/video conferencing (one source to many viewers) - ability to play videos (only need one format, and it doesn't matter which one) - ability to go to a specified time index during video playback (to within a 500ms) - ability to know the current time index during video playback (to within a 500ms) - interface to webcam devices on all target platforms (Linux, Windows, Mac OSX) I don't need or want any GUI support.  I want the video playback functionality to simply provide me with a flat RGB frame buffer, which I can then display myself (in wxPython). 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. How does gstreamer compare with kamaelia? 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.
