GDR Refresh Rate
0
- 240
GDR stands for 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, for example, then each frame
will have a set of macroblocks equal to
1/30
th
of the frame that are intra
refreshed, so that, over 30 frames, the
entire picture is intra refreshed).
Turning on GDR can prevent the
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, but also the 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.
Sample Rate
16000
32000
44100
48000
The sample rate of the audio.
Bit Rate
12Kbps – 320Kbps (
128Kbps
)
The bit rate of the audio.
