Linux Command for getting a dump of hex values bytes from Pcap File

Question

I require a linux command to display a Hexdump of PCAP File. Currently I am using xxd PcapFile.pcap command. With this I am getting a hexdump of pcap file along with other bytes inserted in between and end which do not belong to the pcap file. These bytes are of carriage return, new line, new page, null characters etc. I do not want the hexdump to display these characters. Is there a proper command which can only display the data bytes from pcap file.

eg:

0000000: d4c3 b2a1 0200 0400 0000 0000 0000 0000  ................
0000010: 0000 0400 0100 0000 590d 9d60 abe9 0700  ........Y..`....
0000020: 3c00 0000 3c00 0000 0010 f393 8870 000c  <...<........p..
0000030: 2998 7ecb aefe 1002 0014 0000 0080 9000  ).~.............
0000040: 0000 0101 0000 0000 0019 fffe 0000 0000  ................
0000050: 0000 0000 0000 0000 0000 0000 0000 0000  ................
0000060: 0000 0000 590d 9d60 abe9 0700 3c00 0000  ....Y..`....<...

The bytes I get in the end and between are:

END: 0000 f404 0000
BETWEEN Each Packet: 0000 f404 0000 0600 0000 f404 0000 0000 0000 0000 0000 dc56 2d01 d204 0000 d204
