Test application

I'm writing a test application that encode and decode an H.264 stream.

The two pipeline (encoder pipeline and decoder pipeline) are connected via an
udpsink and udpsrc on the loopback.

The problem is when the encoder changes resolution, the output on the decoder
is corrupted. I tested with VLC and it is able to show correctly the stream.

>From logs on the decoder side, I can see that the h264parse send the new caps
to vaapidecodebin but the vaapidecode negotiate something like sink pad new
resolution src pad old resolution.

In attachment my test source code.
