• VideoBitrateAllocation AllocateDefaultBitrateForTesting (const size_t num_spatial_layers, const size_t num_temporal_layers, const Bitrate & bitrate)

  Create VideoBitrateAllocation with |num_spatial_layers|,

  |num_temporal_layers| and |bitrate|. |bitrate.target_bps()| is the bitrate of

  the entire stream. |num_temporal_layers| is the number of temporal layers in

  each spatial layer.

  First, |bitrate.target_bps()| is distributed to spatial layers based on

  libwebrtc bitrate division. Then the bitrate of each spatial layer is

  distributed to temporal layers in the spatial layer based on the same bitrate

  division ratio as a software encoder. If a variable bitrate is requested,

  that is, |bitrate.mode()| is Bitrate::Mode::Variable, the peak will be set

  equal to the |bitrate.peak_bps()|.
