             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.

           quality.

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

           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)
