Don't bank excess bits for later use
Ignore bitrate buffer overflows. If the encoder uses so few bits that the reservoir of
available bits overflows, ignore the excess. The encoder will not try to use these
extra bits in future frames. At high rates this may cause the result to be undersized,
but allows a client to play the stream using a finite buffer; it should normally be
enabled.
cap_underflow=[1|0] (default: 0)
Don't try to make up shortfalls later
Ignore bitrate buffer underflows. If the encoder uses so many bits that the reservoir
of available bits underflows, ignore the deficit. The encoder will not try to make up
these extra bits in future frames. At low rates this may cause the result to be
oversized; it should normally be disabled.
speed=<number> (0.00..1.00, default: 0.00)
Encoding speed
Higher speed levels favor quicker encoding over better quality per bit. Depending on
the encoding mode, and the internal algorithms used, quality may actually improve, but
in this case bitrate will also likely increase. In any case, overall rate/distortion
performance will probably decrease.

Supported strings: vbr vbr_bitrate managed
Default: VBR
Bitrate mode
Bitrate mode: VBR: You specify a quality and (optionally) a minimum and maximum
bitrate VBR (bitrate): The specified nominal bitrate will be used for selecting the
encoder mode. Managed: You specify a nominal bitrate and (optionally) a minimum and
maximum bitrate VBR is recommended, managed bitrate might result in a worse quality
nominal_bitrate=<number> (0..1000, default: 128)
Nominal bitrate (kbps)
Nominal bitrate (in kbps) for managed mode
quality=<number> (0.0..10.0, default: 3.0)
VBR Quality (10: best)
Quality for VBR mode 10: best (largest output file) 0: worst (smallest output file)

Encoding mode. If you select Auto, the mode will be taken from the samplerate.

Quality (10: best)
complexity=<number> (0..10, default: 3)
Encoding complexity
nframes=<number> (1..10, default: 1)
Frames per Ogg packet
bitrate=<number> (0..128, default: 8)
Bitrate (kbps)
Bitrate (in kbps). Set to 0 for seleting the standard bitrates for the encoding
mode.
vbr=[1|0] (default: 0)
Variable bitrate
abr_bitrate=<number> (0..128, default: 0)
Average bitrate (kbps)
Average bitrate (in kbps). Set to 0 for disabling ABR.

dtx=[1|0] (default: 0)
Enable file-based discontinuous transmission
cbr=[1|0] (default: 0)

For constant bitrate, choose a target bitrate. For variable bitrate, choose a nominal
quality.

drop_frames=[1|0] (default: 1)
Enable frame dropping
Drop frames to keep within bitrate buffer constraints. This can have a severe impact
on quality, but is the only way to ensure that bitrate targets are met at low rates
during sudden bursts of activity.
cap_overflow=[1|0] (default: 1)
Don't bank excess bits for later use
Ignore bitrate buffer overflows. If the encoder uses so few bits that the reservoir of
available bits overflows, ignore the excess. The encoder will not try to use these
extra bits in future frames. At high rates this may cause the result to be undersized,
but allows a client to play the stream using a finite buffer; it should normally be
enabled.
cap_underflow=[1|0] (default: 0)
Don't try to make up shortfalls later
Ignore bitrate buffer underflows. If the encoder uses so many bits that the reservoir
of available bits underflows, ignore the deficit. The encoder will not try to make up
these extra bits in future frames. At low rates this may cause the result to be
oversized; it should normally be disabled.
speed=<number> (0.00..1.00, default: 0.00)
Encoding speed
Higher speed levels favor quicker encoding over better quality per bit. Depending on
the encoding mode, and the internal algorithms used, quality may actually improve, but
in this case bitrate will also likely increase. In any case, overall rate/distortion
performance will probably decrease.
default_timescale=<number> (default: 25)
