Maybe it's related to the caps negotiation; there's bytstream and avc
formats. These are sort of new (at least with regards to gst-openmax),
so AFAIK they have not been implemented there. You might want to force
the caps, or hack the code to specify one or the other; your hardware
might work only with bytestream for example.
Also, it's usually useful to split the pipeline; say, receive the data
from the payloader and save it to a file, and then try different
pipelines to decode it.
