glcolorconvert: Copies the GstMeta twice
In glcolorconvertelement
, we copy the GstMeta twice, which causes them to be duplicated.
They're first copied in gst-libs/gst/gl/gstglcolorconvert.c
, which was added in !2094 (merged) .. but the element also does a copy at ext/gl/gstglcolorconvertelement.c
which calls basetransform to do it.
I'm totally unsure which one we should keep. My gut feeling is that metadata copying being in the element, but I'm not sure why this was changed in !2094 (merged).
