John;
Null packets are what encoders provide when there is no other data to
send.
If the total data rate is more than 19.39 mb/sec, then you've got a
problem. There has to be a setting on the encoder or mux to specify
the maximum output bit rate and whether to furnish null packets to pad
out that bit rate, which is generally what one wants to do.
Video bps + audio bps + psip/psi bps + null packets bps = total bit
rate (assuming no packetized data streams)
I don't see any issue with bit rate in this sample. The mux rate is
19.39, there are no CRC-32 errors, no continuity_counter errors. If
there were too many bits per second, these would signal it.
I do wonder why the image looks to be 4:3, since HD video by
definition is 16:9.
Notice the redistribution control (rc) on the video?
