SVG overlay plugin

[Olivier Aubert-2]

Hello

I have written a svg-overlay element in python (see
http://svn.gna.org/viewcvs/advene/trunk/lib/advene/util/svgoverlay.py ),
which fits the bill for my application. However, I would like to use
multiple such overlays, and the python overhead will start to show (it
already does on some platforms). Thus I would like to port it to C.

My question is: what is the appropriate plugin to base this work on? The
cairotimeoverlay seems self-contained enough to serve as a base, but,
having been bitten before, I would rather be sure to use an up-to-date
and adequate reference.

Best regards,
Olivier

The cairo elements in gst-plugins-good are not in particularly good
shape, it's probably best not to use them as a base.

Maybe there's something suitable in
http://cgit.freedesktop.org/~company/gst-plugins-cairo ?

Cheers

Hello!

How's the svg overlay in C going? I wrote a cairoimageoverlay element to
use in my application, but it only accepts png files, at least AFAIK,
and it's not really good yet. It can be found in
http://git.holoscopio.com/git/hplugins.git. Maybe we could join efforts
to build an imageoverlay element?

Hello Luciana

I have submitted a patch for gst-plugins-bad that implements a
rsvgoverlay element: https://bugzilla.gnome.org/show_bug.cgi?id=435120
Just waiting now for some feedback (esp. from the People Who Have The
Right To Commit).
