accessing a camera on Android

[Chuck Crisler]

No, I haven't selected a Windows tablet yet. My goal is to learn Java and
mobile programming, starting with Android (because I own an Android phone),
then Windows/Windows tablet and Linux/Java, with an emphasis on multimedia.
GStreamer is the best multimedia platform around (that I know of) and is
(somewhat) portable across those platforms. As a personal goal I am working
to develop a video conferencing app that runs on those platforms, simply
because I am familiar with GStreamer and have worked in video conferencing
for many years. This is a personal/professional development project.

I had already thought of the appsrc approach. My only concern is whether or
not Android allows me access to the image buffers. I have an app that
displays from a camera now, so I have the structure and the correct
callback, but haven't checked to verify access to the actual buffer -
tonight's project. Android seems to be rather paranoid and restricts access
to many things, either to make development *VERY* easy (once you figure it
out) or for security.

As far a writing a 'proper' source element...well I spent many years
working on lower level Windows video (DX and DirectShow). So I may take
that on along with first attempting to finish the camera work you began. I
really want to use the same basic pipeline on all of the systems. And, of
course, contributing to GStreamer would be another asset on my resume.

Thank you for the guidance.
