Configuration: Encoder > Audio
If configuring audio for multiple bit rate, you can specify separate encoder settings for up to
three audio encoders. When Audio Rate2 or 3 is enabled, the
Sample Frequency
must be
44.1 KHz and only bit rates compatible with 44.1 KHz can be selected. As with video, any
change in the settings for any of the audio encoders will cause a brief interruption of video
and audio for all three encoders. All streams being sent from the unit (including multicast and
push) are interrupted. Any active HTTP or RSTP clients will be dropped and any archive file
in progress will be closed.
Picture Center
Quality Difference
Sets the quality difference between the center of the image and the
edges. By reducing quality on the edges the encoder may be able to
improve the quality of the center of the image at a given bit rate.
Buffer Size
Sets the rate control buffer depth in milliseconds. Larger buffer sizes
may improve video quality and make the encoder's rate control more
consistent. This value is also used as the .wmv pre-roll for the stream
header so the player generally buffers at least this amount of data and
as a result larger buffer size values will increase end-to-end latency.
Video Rate2
Use to configure multiple bit rates. Check
Enabled
to display the
configuration settings for Video Rate2. Once enabled, VideoRate2 and
VideoRate3 are available for selection on the Multicast, Server, and
Archiver pages. If selected on those pages, an error will display if you
attempt to disable them on this page. Video Rates1, 2, and 3 must have
different Target Bit Rates.
Video Rate3
Use to configure multiple bit rates. Check
Enabled
to display the
configuration settings for Video Rate3. Video Rates1, 2, and 3 must
have different Target Bit Rates.
