            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)

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

            Use constant bitrate

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

            target_bitrate=<number> (45..2000, default: 250)

            Target bitrate (kbps)

            quality=<number> (0..63, default: 10)

            Nominal quality

            Maximum keyframe interval

            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.
