QVPRO-Codec, even after selecting the correct Network Interface (if not grayed out) and
clicking on the Discover button, and you are certain that the switch passes Ethernet
broadcast packets, then try the other LAN port. By default, the QVPRO codec will output
broadcast Ethernet packets back to CodecManager on LAN1. However, these multicast
discover packets may go out on LAN2 if selected as the multicast interface.

5.

Open a shell window (On Windows™ select “Start/Run…” and type “cmd”).

6.

Clear the ARP cache by typing “arp –d” and hit Enter.

7.

Try pinging the system by typing “ping 192.168.1.23”.

8. If all else fails, you can reset the network settings by going to:

http://www.qvidium.com/reset

. Then copy the file “autorun” to a USB flash stick, and

plugging it into your codec. The autorun file must be saved directly, not first converted to a
text file. It should not be saved as “autorun.txt”. On Internet Explorer, use the Save Target
As…
command and select All Files for the File Type. Then, plug the flash stick into the
QVPRO. It will then reset all the network settings back to the defaults (192.168.1.23).

Cannot Receive Encoded IP Packet Stream at Decoder

1. On the encoder, check that is is powered-on, and check the Encoder/Status page to make

certain that the encoder bitrate is non-zero. It the bitrate is zero, then go to the next step to
get a valid output packet stream.

2. Make certain that decoder is powered on and connected to your network.

3. Check that the LAN link-light and activity lights for the RJ-45 Ethernet port on both encoder,

decoder, and switch(s) are lit.

4. Make certain that you have entered the correct IP address for the destination (under

Encoder/Profile) and the correct gateway (under Network/Configure) if the receiver is on
another subnet.

5. Try pinging the destination IP address for the decoder from the encoder clicking on

Network/Ping and entering the IP address for the decoder device.

6. If you cannot ping the decoder from the encoder, then your stream may be blocked by a

firewall at the decoder side. If necessary, add a Network Address Translation (NAT) rule to
the decoder-side firewall to port-forward incoming packets from the UDP port you set on
the encoder to be forwarded to the decoder.

Encoder does not start or is not outputting any packets

1. Check that a valid video signal is connected to the video Input you have configured. Use

the Encoder/Profile page to select the video input that you have connected and wish to
use. The SDI input will auto-sense and select among SD-SDI, HD-SDI, and 3G-SDI
signals. If using HDMI input (QVPRO-only), make certain that the video source is HD and
is not encrypted. Make certain that you Saved the profile and afterwards hit the Start
menu item.

2. If the bitrate is zero, then check for a valid video input.

3. If you have a valid video input, then check Encoder/Show Log to see whether there are

any errors.

4.

If the log says “Video not LOCKED: waiting for valid input”, then check whether there is

embedded audio on the SDI or HDMI feed. At present, the codec requires an embedded
audio signal to lock onto before it can start encoding.

5. If you are trying to SDI video input, please check under License/SDI to see that you have a

license key for that feature
