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.

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.

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.

bitrate_mode=<string>

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.

Use voice activity detection

dtx=[1|0] (default: 0)

Enable file-based discontinuous transmission

cbr=[1|0] (default: 0)

Use constant bitrate

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

drop_frames=[1|0] (default: 1)

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)

Default timescale

For formats, which support only constant framerates, set the default timescale here

default_frame_duration=<number> (default: 1)

For formats, which support only constant framerates, set the default frame duration
