GstBaseTextOverlay not packaged for use by other plugins?

[George Hawkins]

I wanted to use GstBaseTextOverlay as the superclass for a new element.

However, I find gstbasetextoverlay.h is not bundled up with the other headers of gst-plugins-base.

https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/blob/master/ext/pango/gstbasetextoverlay.h

E.g. here one can see the files included in the Ubuntu libgstreamer-plugins-base1.0-dev package:

https://packages.ubuntu.com/disco/amd64/libgstreamer-plugins-base1.0-dev/filelist

gstbasetextoverlay.h isn't among them.

Does this mean that if I want to make a text overlay related element, I always have to manually copy gstbasetextoverlay.h and gstbasetextoverlay.c into my own plugin project?

Regards,

/George

Well, that's one option, if it's compatible license-wise. Depends what
you want to do exactly. There are other subtitle/overlay type plugins
that have copied some of the relevant code. You're certainly right in
that it's currently not a public base class.

You could also write a new element based on the GstAggregator base
class instead.
