Abstract

The invention discloses a coding method of an instant video and electronic equipment and belongs to the video field. The method comprises the following steps of acquiring an interest area in a current instant video frame; if a network bandwidth satisfies a first preset condition, dividing the instant video frame which at least includes the interest area into at least one macro block, and setting and composing a quantization parameter corresponding to the at least one macro block; according to the quantization parameter, coding the at least one macro block and generating the instant video frame after coding. Through the quantization parameter used for indicating a fine degree of the macro block in a coding process, coding is performed on the at least one macro block so that transmission efficiency of the instant video is improved and a user experience is increased.

Description

technical field [0001] The invention relates to the video field, in particular to an instant video encoding method and electronic equipment.
