Video Compression – This section allows you to configure video compression parameters for any of the
three available codec instances (Primary, Secondary and MJPEG).
o
Enable Encoder – Allows you to enable the encoder to be utilized
o
Custom Name - Allows you to define a custom name for that specific encoder
o
Encoder type - Allows you to choose your codec (H.264 is the only codec supported right now)
o
Profile – Select the H.264 profile you wish to use
o
Resolution – Select the video resolution to stream
o
Frame skip rate – Select the number of video frames to be skipped from the input in order to
create an output stream with a certain frame rate (resulting frame rate is always shown, based on
the selected skip rate)
o
Target bit rate – Select the desired target bitrate
o
Rate control – Select between Constant Rate or Variable Rate
o
Minimum QP / Maximum QP – These parameters allow you to specify the compression range
that the codec will use to determine image quality during compression. In order to force a specific
quality setting, you can set the minimum and maximum to the same value. The lower the value,
the better the quality will be. We do not recommend changing default values unless you have a
good understanding of the H.264 compression process.
o
Intra interval – Defines the GOP size
o
VBR aggressiveness is unique to IONODES encoders and proposes various levels (disabled to
aggressive) of motion triggered rate control. The more aggressive the setting, the more variation
motion will have on the rate control. It is strongly suggested to disable VBR aggressiveness for
low bit rate scenarios (below 1Mbps) as this parameter may negatively affect perceived video
quality
o
Multicast Assignation – This allows you to manually configure the Multicast IP & Port for the
outgoing stream; when the automatic setting is enabled the encoder will automatically assign the
Multicast IP & Port based on the range defined in the Network > Multicast section of the web
interface.
– Please note that, when in Manual mode, the multicast settings for the specific stream
will override the global settings.
•
Point to Point – This section allows you to configure point to point video connections for creating
persistent video streams from the encoder to a network endpoint. A maximum of 3 point-to-point
connections can be defined & enabled.
