Frame Rate Divider
1
, 2, 4
Used to encode at less than the input frame
rate (for example, an input frame rate of
30fps with a divider of 2 would cause an
output stream of 15fps).
Number of B-frames
1
– 3 (
1
)
The # of frames after a P-frame that the
next P-frame occurs. A value of “1” means 0
B-frames occur. A value of “2” means 1 B-
frame, and so on.
GDR Refresh Rate
0
- 240
GDR- Gradual Decoder Refresh. When set to
0, GDR is disabled. When set to a nonzero
value, it determines the intra refresh rate,
which is used to calculate the number of
vertical rows to be intra refreshed per frame
(if GDR is set to 30, then each frame will
have a set of macroblocks equal to 1/30
th
of
the frame that are intra refreshed. Over 30
frames, the entire picture is intra
refreshed). Turning on GDR can prevent
generation of large I-frames and allow for
lower latency encode/decode since the
decoder buffer can be reduced.
GOP Size
10 – 240 frames (
60
)
I-frame frequency [
Note 2
].
Maximum Delay
0 – 9999 (
2000
)
# of ms to buffer. The higher the value, the
smoother the encode and higher the latency.
Audio Enable
True
, False
True -> Encode audio.
Audio Info (Entries for each of the 4 subchannels within a source)
Enable
yes (for Sub Channel 1)
, no
Used to select which subchannel should be
used for the audio source. Only one
subchannel can be enabled.
Codec
DSP AACLC
ARM AACLC
ARM AACLC MPEG2
ARM AACHE
ARM AACHE V2
The codec to use for audio. The codec(s)
supported depend on what was licensed.
DSP AACLC is not a valid option in this
release and should not be selected.
