Look at the output of gst-inspect $your_decoder

Check the Rank, it needs to be >64

Check the sink pad template caps, compare them with other decoders that

Check the element factory "Klass" tags, compare them with other decoders
that work on the desktop (should contain "Decoder" and probably "Audio"
or "Video").
