APPENDIX B: Troubleshooting



Problem:

Web interface does not come up

-Is the Ethernet cable plugged in to the board solidly (do you see the link light)?
-Does the SBE264-DVR-23 IP address and the PC IP address have the same first 2 values (or, if

netmask is set to 255.255.255.0, the same first 3 values)?

-Do the SBE264-DVR-23 and the PC running VLC have the same netmask? (Default value is

255.255.0.0)

-You can check the netmask of the PC by typing ifconfig in Linux

-Are all firewalls on the network turned off?

-Try connecting the PC directly to the board without any routers etc.

-Can the Linux PC and target board see each other on the network?

-Try pinging the SBE264-DVR-23 IP address from the Linux PC.

-Try pinging the Linux PC from the SBE264-DVR-23.



Problem:

Do not see video in VLC

-Does the IP address set in “Dest Address” equal the IP address of the PC running VLC?

-Does the port number in “Dest Port” equal the value entered in the URL for VLC?

-Does the video coming out of the source match the resolution in the encoder settings?

-Is the PC fast enough for 1080p decode on VLC?

-Does the PC have enough DDR to handle 1080p decode on VLC?

-Is VLC version 1.1x or later?



Problem:

Receive an error message while building

-Were all modules for Linux installed? (See

Error! Reference source not found.
