Sebastian Dröge 8748ce94f4 amc: If we find multiple codecs with the same name, just merge them 
On the ODroid C1+ the H265 and H264 have the same name but are listed as two
different codecs. We have to handle them as the same one that supports both,
as otherwise we will register the same GType name twice which fails and we
then only have H265 support and not H264 support.
