1. A video processing method, comprising:
obtaining a bitstream and signaling information, the bitstream including a plurality of independent layers corresponding to a plurality of video sources, wherein the signaling information includes one or more of:
a first parameter, indicating a number of layers in the plurality of independent layers;
a second parameter, indicating that layers in the plurality of independent layers are independently coded; and
a third parameter, indicating that one or both of a profile-tier-level and hypothetical-reference-decoder (HRD) parameters apply to the plurality of independent layers; and
decoding the bitstream according to the signaling information.
