Operation Manual

 Connect: This parameter controls whether or not the encoder should actually establish a

connection with the server. If you set this parameter to No, the encoder will run but no

data will be transmitted. This is useful to pre-configure a session, and turn it on later

when it comes the time to broadcast.

Notes:

 The maximum aggregate RTMP performance for the B264 is 12 Mb/s. If the unit has

two encoder channels, this limit applies to the sum of their video bit rates. For example,

if one encoder channel is configured for RTMP at 8 Mb/s, the other can only be

configured for RTMP at 4 Mb/s or less. The limit does not apply to encoder channels

configured for UDP/RTP/ASI streaming.

 Using one of the encrypted variants of the protocol (rtmpe, rtmps, rtmpte, or rtmpts)

will also have a performance impact and will reduce the maximum usable rate.

 Performing a firmware update while the encoder is running RTMP at high bit rates may

cause service interruptions to the RTMP stream. If you need to update the firmware, we

recommend that you do so during a maintenance window.

 Some CDNs (such as YouTube, for example) only accept frame rates up to 30 fps and

prefer progressive content. The B264 can convert any input signal to progressive at a

lower bit rate (see the Basic Tab – Video Configuration section).

 In RTMP Mode, the B264 will force Closed GOP operation (see the Advanced Tab –

Video Parameters section) as required by some CDNs.

The Apply/Cancel Buttons

The Apply/Cancel buttons are available at the bottom of the Basic, Advanced, and Connection

screens. These are not separate buttons – they are multiple instances of the same buttons,

repeated on each screen for convenience. If no changes have been made to the settings, the

Apply/Cancel buttons are grayed out; once any changes are made, they become available.

Changes do not take effect until the Apply button is pressed. If you make changes but decide

not to apply them, click on the Cancel button and the user interface reverts to where it was

before. Once you click on the Apply button, the changes are implemented.

No changes to Apply

Configuration Changed

In general, most changes will cause the encoder channel to stop and start again, causing a brief

(2-second) interruption to the stream. Changes to the following parameters are implemented on-

the-fly, without stopping the encoder:

 Audio Source in Basic Tab – Audio Configuration

 Language Code in Basic Tab – Audio Configuration

 Any CC/AFD configurations made in Advanced Tab – VBI/Ancillary Data Insertion

 Audio Gain L/R in Analog Audio Parameters
