so I check GStreamer debug logs and in all the output I get, I found things
like this:
gst_element_get_compatible_pad:<vaapidecode0> Could not find a compatible
pad to link to cluttergstvideosink0:sink
gst_element_link_pads_full: no link possible from vaapidecode0 to
vaapidecode0
So it seems that the link between vaapidecode and vaapidecode doesn't work.
Is there something to fix it or a workaround?
Thank you.
