2.1 Quickstart Encoder Configuration
Below is a simple procedure to quickly start streaming from one QVENC4K for encoding to a
compatible video decoder.
1. Enter
http://<IPAddress>
where <
IPAddress>
is the IP address of the QVidium
QVENC4K
™ HEVC UHD-HDR Video Encoder unit that you want to configure as an encoder.
(See section 1.2 Network Settings1.2 to get or set the IP address.)
2. Click Profiles from the menu on the left. Then, either click to highlight an existing encoder
profile you wish to edit and click Edit , or click Create
or “
+
” to create a new encoder profile.
The
“
Encoder Profile
” interface should then display in the main area to the right of the
menu.
3. At this point, the web interface displays a list of all the configurable video and audio encoding
parameters, We recommend that you initially use all of the defaut settings for these
parameters, unless there is an obvious change required for your application.
4. Next, configure one or more of the four Output fields, which are listed after the audio settings
in at the end of the parameter list. Click to select the desired video transport protocol, and
enter the destination IP address and UDP port or URL and any other parameters associated
with the protocol that you selected for this output
. For “Listener Mode”, you can leave the
Destination IP address blank.
5. When sending a video stream over a LAN or other private hardwired network, you can select
UDP for the IP transport. The UDP protocol is the simplest to configure and incurs the least
amount of added delay. However, to send a video stream over the public Internet or a
wireless network with the potential for packet loss, we strongly recommend that you choose a
video transport protocol designed to recover from potential packet loss, such as our patented
QVidium ARQ protocol. If you also require interoperability with a third-party decoder, you may
wish to select from among SRT, RIST, or Zixi. To stream to a content delivery network, such
as Facebook or Youtube, we recommend selecting RTMP or HLS.
6. When selecting a particular IP transport protocol, the web interface will change to show the
available parameters that are specific to that protocol. At a minimum, you will need to select a
UDP port or URL. Most protocols will require a destination IP address or DNS name for the
receiver, but several of the protocols, such as QVidium ARQ, RIST, and SRT, allow you to
leave the destination blank and have the receiver initiate the stream. We refer to this
operation as Listener Mode or Pull Mode.
7. After configuring an Output field, you must click on Update URL to save the changes for that
output. Next, click the Save button to save the profile. None of your changes will be saved nor
have any effect unless you first save them. These changes are stored in permanent memory
and will persist even after a power failure.
8. To then start a stream, click the Start button associate with that profile.
Figure 6, below, provides an example of a profile with its settings configured to send to four unique
destinations, each with a different IP transport protocol.
