GstMeta from GstGLFilter

[Cyril Baletaud]

Hi all,

I need to draw on gl texture in a pipeline.
I'm reading for GstGLfilter subclassing, but i need to access GstMeta from GstBuffer.

How can i access GstBuffer from GstGLFilter ?

Thanks

You can get at the GstBuffer using the filter virtual method of the
GstGLFilterClass.

See
https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-libs/html/GstGLFilter.html#GstGLFilterClass

In order to call the filter_texture virtual method correctly, you should
call
https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-bad-libs/html/GstGLFilter.html#gst-gl-filter-filter-texture
inside your implementation.

Cheers
-Matt
