Subject: [PATCH 04/14] Fix error when h264 stream resolution changes.
 Contributes to JB#17654

The decoder is able to determine new configuration from the bytestream
so allow it to decide when to reconfigure the output port instead
of prematurely forcing an update which causes the decoder to throw an
error.
