ENCODING METHOD, DECODING METHOD, CODE STREAM, ENCODER, DECODER, AND STORAGE MEDIUM

Disclosed in embodiments of the present application are an encoding method, a decoding method, a code stream, an encoder, a decoder, and a storage medium. The decoding method comprises: determining a preset parameter corresponding to a zero run value (S601); if the preset parameter meets a first preset condition, performing context model-based decoding processing on at least one first-type syntax element identification information, and performing bypass model-based decoding processing on at least one second-type syntax element identification information, to determine a value of the at least one first-type syntax element identification information and a value of the at least one second-type syntax element identification information (S602); and determining the zero run value according to the value of the at least one first-type syntax element identification information and the value of the at least one second-type syntax element identification information (S603). In this way, the hardware throughput rate can be
