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)

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.

complexity=<number> (1..10, default: 10)
Encoding complexity
frame_size=<string>
Supported strings: 25 50 100 200 400 600
Default: 200
Frame size (ms)
Smaller framesizes achieve lower latency but less quality at a given bitrate. Sizes greater than 20ms are only interesting at fairly low bitrates.
dtx=[1|0] (default: 0)
Enable discontinuous transmission
inband_fec=[1|0] (default: 0)
Enable inband forward error correction
bandwidth=<string>
Supported strings: auto narrow medium wide superwide full

bitrate=<number> (0..128, default: 8)

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.

For formats, which support only constant framerates, set the default timescale here
default_frame_duration=<number> (default: 1)
