Operation Manual

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:

o Connected: The encoder has established a connection with the RTMP server

and is transferring data.

o Waiting for Encoder: The encoder is not attempting to connect to the RTMP

server. The reasons are:

 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).

o Not Connected: The encoder is running, but it is unable to connect to the

RTMP server. Possible reasons are:

 The encoder cannot contact the server.

 The RTMP parameters are incorrect.

 The server was specified as a host name, and the encoder cannot convert

that to an IP address (i.e., no DNS, or server name misspelled).

Check the Admin Event Log Tab for more details.

 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.
