Error in linking h264parse to vaapidecode

[Chuck Crisler]

First, use gst-inspect for both the h264parse and vaapidecode to see if the
pad caps are compatible. It seems that they must not be. Then put a caps
filter between them. There are examples of using a caps filter in the
documentation. You can also enable/increase logging to see why it is
failing to link the pipeline. Start slow because some of the filters
generate a lot of messages. Pick the ones that are responsible for the
linking and increase the logging level on those. I think GST_ELEMENTS may
be the primary element of interest. Enable logging with export
GST_DEBUG=*:3 to start, replace the * with element names and '3' with 4 or
5.
