decoding FU-A H.264 NALS using gstreamer

The end of the frame is indeed marked by an end bit == 1. The start of the
frame is marked by a start bit == 1. All of the FU-A packets in between
have both == 0. If you can, capture a packet trace to allow you to examine
all of the packets properly (install wireshark). Knowing your
decode/display pipeline is important. Also, knowing your video source is
important. This sounds like very strange stream.
