possible for the IP Output Rate to be less than the intrinsic bit rate of the encoder for
short periods of time, depending on server and network conditions. The encoder will
buffer the bitstream and attempt to "catch up" in these cases. If it cannot, audio/video
bitstream data may be dropped.
• Encoder RTMP Status: This indicator reports the state of the RTMP connection to the
server. The possible states are:
Connected: The encoder has established a connection with the RTMP server
o
and is transferring data.
Waiting for Encoder: The encoder is not attempting to connect to the RTMP
o
server. The reasons are:
Not Connected: The encoder is running, but it is unable to connect to the
o
RTMP server. Possible reasons are:
• Server Connection: RTMP can be optionally configured with a primary and a backup
server. If the primary server cannot be contacted, the encoder will attempt to connect to
the backup server. This field indicates which server (Primary or Backup) the encoder is
currently connected or attempting to connect.
• Video Buffer %, Audio Buffer %: The encoder has separate buffers for audio and
video. These buffers are used to temporarily store the bitstream if there is no enough
network and/or server bandwidth. However, if this situation persists, the buffers start to
fill up. These indicators report the current state of the buffers. If they overflow, data is
dropped. Ideally, these buffers should stay empty (close to 0%).
• Dropped Packets: If the buffers overflow, data is dropped. The encoder will drop entire
access units (an audio block or a video frame). This indicator has a count of the number
of access units dropped for the current connection. This count resets when a new
connection is established.
ASI Outputs Tab
The 9223 card has two ASI output ports that can be independently configured. Use this tab to
configure and manage the ASI output ports.
ASI Ports: Configuration Tab
The default appearance of the Configuration tab is:
The encoding core is not running (i.e., the encoder is not generating
bitstream). This can be because the encoder is explicitly stopped
(Encoder State set to Stopped in Basic Tab – General Configuration) or
it has no valid input.
The RTMP output is configured not to connect to the server (Connect set
to No in the RTMP configuration section).
The encoder cannot contact the server.
The RTMP parameters are incorrect.
