<div>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.<br>
<br>
</div>
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.<br>

You can get NV21 or YV12 raw frames on all android devices (tested
with 4.1+), I use the appsrc approach since 3 years and it works
fine, <br>

<div>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.<br>

Thank you for the guidance.<br>

</span>I started merging this, just have to find
some time to finish it. It's<br>
mostly boring shuffling around of code, not really
development work.<br>
<br>
Note: the code is there (see links in the bug
report), just has to be<br>
integrated properly and cleaned up a bit<br>

<br>
</span>What Windows tablet, and do you already
have GStreamer running there? ;)<br>
But same answer as what Nicolas replied, appsrc...
or write a proper<br>
source element.<br>
