Audio Enable
True
, False
Set to “True” to encode audio.
Audio Info
(Entries for each of the four subchannels within the source)
Enable
yes (for Sub Chan 1)
no
Used to select which subchannel should be used for
the audio source. Only one subchannel can be
enabled. In this release only Sub Channel 1 is
supported.
Codec
ARM AACLC
ARM AACLC MPEG2
ARM AACHE
ARM MPEG1L2
The codec to use for audio. The bitrate range for
AACLC is 32Kbps – 384Kbps (though staying above
64Kbps is recommended for best results). The
bitrate range for AACHE is 32Kbps – 64Kbps.
Bitrate
12Kbps – 384Kbps
(
128Kbps
)
The bitrate of the audio.
Mode
Mono
Stereo
Select between stereo and mono inputs.
Source
HD-SDI
HDMI
Analog
None
Where to get audio for that subchannel.
Pid
(UDP/TS Only)
0 – 8191
(
120,121,122,123
)
If UDP format is selected, the PID to use for that
audio channel.
Max PTS-PCR
(UDP/TS Only)
0 – 500 (
250
)
Allows user to specify a smaller interval than 250ms
between PTS and PCR. This is for systems that
require tighter PTS-PCR intervals. It is generally
recommended to leave this value at 250. Certain
decoders may require a value of Max PTS-PCR
similar to the video delay. If an issue is encountered
with a specific decoder, please try setting this value
to the same value as video delay.
Format
(UDP/TS Only)
ADTS
LATM
Allows user to select between ADTS headers for AAC
and LATM headers.
