If experimental min bitrate value is not configured, set the min bitrate for the first simulcast stream equal to kDefaultMinVideoBitrateBps (=30kbps). Min bitrate depends on resolution. At absence of the experimental min bitrate override, we got high min bitrate values for high resolutions (600kbps for VP8 720p, for example) before. That led to encode pauses [1] which is an undesired behavior.
