<div dir="ltr">It would be great to incorporate more recording methods into Record. We've plans to also incorporate stop-motion and time-lapse into record also. It could become a behemoth of an activity though... perhaps it might benefit from being broken into different components (a.k.a. tamtamization)?<br>
<br>As for Record's UI, it uses windows to allow for its custom fullscreen mode and for embedding widgets over video (seen, for example, in the picture-in-picture modes and the "info" button). <br><br><br><div class="gmail_quote">

I don't know about integrating it into Record, but the other issues<br>
are fairly easy to resolve. I wrote a Python module over the summer<br>
to interface v4l2 cameras that returns Pygame surfaces. Capturing<br>
images is near instant (~20ms for 640x480 RGB). Autogain and<br>
autowhitebalance can be disabled using v4l2 camera controls. There is<br>
support in my module for the hflip and vflip controls, but adding<br>
additional controls is trivial.<br>
<br>
Alternately, we could just use a little utility in C to access any<br>
v4l2 camera control. Since the module I wrote is for Pygame and is<br>
eventually going to be cross platform, adding v4l2 specific stuff to<br>
it is probably not the greatest idea.<br>
<br>
It may just be better to skip sticking it in Record and make a<br>
standalone activity, since Record seems to have plenty of issues on<br>
its own without a big new feature. There wouldn't be much code<br>
duplication if Panorama doesn't use gstreamer anyway.<br>
