Add setter and getter for GstVideoCropMeta
GstVideoCropMeta does not have any setter and getter, making it impossible to set or get GstVideoCropMeta fields from Python via gi-introspection.
This patch adds the neccesary setter and getter.
Thanks for the patch.
So how would adding crop meta work? You'd call gst_buffer_add_meta() with GST_VIDEO_CROP_META_INFO? Or can g-i not modify the struct directly because there's no GType registered for it?
I think my real question is whether _add_crop_meta() should be turned into a function so that it's usable from bindings, but maybe that wouldn't help?
I am no expert on gi at all, I just deduced that this solution got things running :).
Example code in python:
info = GstVideo.VideoCropMeta.get_info()
print "This is bad"
meta = gstBuf.add_meta(info, 0)
GstVideo.buffer_set_video_crop_meta(meta, x, y, w, h)
You can retrieve the video_crop_meta using:
Not sure if I answered your question at all, so feel free to shoot if necessary.
