Number of Stream Types Allowed and Usage †
Metering
RTP only. Default = Disabled. Metering is designed for RTP
transport only and is configured for each encoder so that all
RTP streams are treated as a group. When metering is disabled,
video frames are sent as soon as they are encoded. This can
result in substantial network traffic burstiness since certain
encoded frames (i.e. key frames) are substantially larger than
other frames. If desired, metering can be used to smooth the
transmission of the video stream. This results in less burstiness,
and can help to prevent packet loss on some networks, but it can
also increase jitter and latency. VBrick recommends the use of
metering only on bandwidth-constrained networks. When you
enable metering, Metering Aggressiveness (see below) defaults
to Medium.
Note: To play metered RTP streams on StreamPlayer, the H.264
playback buffers must be set to 1200 msecs or higher for UDP
and 2000 msecs or higher for TCP. In StreamPlayer go to
Preferences > MPEG4/H264 > Buffer Size > UDP Playback/
TCP Playback.
Metering Aggressiveness RTP only. Low, Medium, High. Default = Medium. Low is least
aggressive; High is most aggressive and will provide smoother
transitions between frames. If Aggressiveness is too high it may
result in impaired video and/or audio and you will see the
Metering Buffer Full Count increment on the Monitor >
Encoder Status > Monitor Global & Streams page. If this
happens decrease the Metering Aggressiveness.
Encryption
Enables encryption for RTP streams. View the topic on
Encryption for more information.
Encryption Key
If encryption is enabled, use the dropdown to assign the
encryption
Key ID
. The
Key ID
must have a valid
Key Value
or the
Apply
will fail.

† The total number of all stream types you can define is 16. This means if you define 8 RTP
streams and 8 MPEG2TS streams, you will not be allowed to define any RTMP or Smooth
streams.
