ICE components ID numbering - Comply to RFC-5245 and RFC-8445
Component ID must be incremented per media starting from 1 as specified in https://tools.ietf.org/html/rfc5245#section-15.1:
<component-id>: is a positive integer between 1 and 256 that
identifies the specific component of the media stream for which
this is a candidate. It MUST start at 1 and MUST increment by 1
for each component of a particular candidate. For media streams
based on RTP, candidates for the actual RTP media MUST have a
component ID of 1, and candidates for RTCP MUST have a component
ID of 2. Other types of media streams that require multiple
components MUST develop specifications that define the mapping of
components to component IDs. See Section 14 for additional
discussion on extending ICE to new media streams.
