opencv: extract some base code to a lib

[filnet]

Hi,

I would like to extract some opencv base code from the opencv plugin to a library.

This would allow plugin writers to create their own opencv easily.

The opencv plugin is in gst-plugins-bad/ext/opencv.

I would like to move gstopencvutils.[h|cpp] and gstopencvvideofilter.[h|cpp] to gst-plugins-bad/gst-libs/gst/opencv.

gstopencvutils provides a number of utilities and gstopencvvideofilter is the base class for writing opencv filter elements.

I think I know how to do it and it will be inspired from the similarly organized ext/gl and gst-libs/gst/gl modules.

My issue is library name:

The gl libraries are named libgstopengl (for the plugin) and libgstgl-@GST_API_VERSION@ for the library.

Shortening opencv to cv will probably not be accepted.

Having two libgstopencv libraries that differ only in one having a version postfix will probably not be accepted too.

Suggestions are welcome...

Philippe.

The latter is the situation of libgstapp-1.0 and libgstapp (plugin).
I see no problem here :)
