I-frame frequency. The number of frames in each

Audio Enable
True
False
Selecting “True” enables encode of audio along
with video. Selecting “False” disable encode of
audio.
Audio Setup (if Audio Enable is set to True)
Codec
ARM AACLC
ARM AACLC MPEG2
ARM AACHE
ARM AACHE V2
Codec to be used for audio encode.
Sample Rate
48000 Hz
44100 Hz
32000 Hz
16000 Hz
Sample rate of audio.
Bit Rate
12
–
384 Kbps
(128
Kbps)
Target bitrate for audio encode.
The bitrate range for AACLC is 12-384 Kbps (though
64 Kbps or higher is recommended for best
results). The bitrate range for AACHE and AACHE
V2 is 32
–
64 Kbps.
Rtp Port (RTP Only)

Destination port for RTP audio.

8191
(250)
Maximum difference between the PTS and PCR in
the audio stream. It is generally recommended to
leave this value at 250. Certain decoders may
require a value similar to the video delay. If an
issue is encountered with a specific decoder, try
setting this value to the same value as the video
delay.
Output Setup
Output Format
RTP
RTSP
UDP
TSRTP
TSFILE
RTMP
ZIXI
Output format of the encoded IP stream.
If UDP is selected, don’t forget to check the value
of TS Rate to make sure it is in line with
expectation.
RTP requires an SDP file for the receiver that
corresponds with the video codec used.
RTSP requires the use of the RTSP URL.
TSRTP causes streaming of TS over RTP. This
format is required for encoding with Pro-MPEG
Forward Error Correction (FEC).
