python post large files to django
I am trying to find the best way (most efficient way) to post large files from a python application to a Django server. If I rely on raw_post_data on the Django side then all the content needs to be in RAM before I can read it which doesn't seem efficient at all if the file received is 100s of megs. Is it better to use the file uploads...

How to generate an audio stream using gst-python?
I'm looking to generate a stream in gstreamer, and I'd prefer to do it from python if possible. This points towards using gst-python, but I don't see a clear way to do it.
