determining at least one point indicated by the coordinate parameter in the current instant video frame;

the at least one point is set to be at least one point in the shape of the user input including the center of the shape of the user input.

305. And judging whether the network bandwidth meets a preset condition, if so, executing the step 306, and if not, ending the step.

Specifically, the numerical relationship between the network bandwidth and the first preset value and the second preset value is determined, and the specific determination manner is not limited in the embodiment of the present invention.

If the network bandwidth is greater than or equal to the first preset value and less than the second preset value, go to step 206;

and if the network bandwidth meets any one of the first preset value and the second preset value, ending the process.

In practical application, the first preset value is 50kb/s, and the second preset value can be 100 kb/s.

The quantization parameter of the macro block is used for indicating the fineness of the macro block in the encoding process, and if the fineness of the macro block in the encoding process is higher, the image details of the macro block are reserved most; if the fineness of the macro block in the encoding process is lower, the image details of the macro block are kept at least;

since the quantization parameter ranges from 0 to 51 in practical applications, the first value may be any value defined by any one of a user and a system between 0 and 25.

Because the attention and picture quality requirements of the two interactive parties on the area indicated by the shape input by the user, such as the area where the human face is located, in the instant video are higher than those of other areas in the scene of instant video interaction, the details of the area indicated by the shape input by the user can be more reserved in the encoding process by setting the quantization parameter of the macro block including all or part of the area indicated by the shape input by the user as a first numerical value, so that the picture quality of the area indicated by the shape input by the user can be ensured in the instant video process, the diversified requirements that the attention of the user is higher than that of other areas in the instant video, the requirements of the user on the definition and the detail reservation amount of the certain area are higher than that of other areas, and other participants of the user who want instant video interaction move the attention to the area specified by the user are met, the user experience is improved.

308. The quantization parameter of the macroblock that does not include the area indicated by all or part of the shape is set to a second value.

Specifically, after detecting a macro block including all or part of the area indicated by the shape input by the user from at least one macro block, acquiring a macro block not including all or part of the area indicated by the shape input by the user;

setting the quantization parameter of the macro block not including all or part of the area indicated by the user-input shape to a second value.

The second value may be any value defined by any one of a user or a system between 25 and 51.

In the scene of instant video interaction, the attention and picture quality requirements of two interacting parties on the area indicated by the shape input by the user, such as the area where the human face is located, in the instant video are higher than those of other areas, so that the quantization parameter of the macro block not including all or part of the area indicated by the shape input by the user can be set to be a second value, and the details of the macro block not including all or part of the area indicated by the shape input by the user are not reserved in the encoding process, so that the diversified requirements that the attention of the user on a certain area in the instant video is higher than that of other areas, the requirements of the user on the definition and detail reservation amount of the certain area are higher than that of other areas, and other participants of the user who want instant video interaction to migrate the attention to the area specified by the user are met, and the user experience is improved. In addition, the occupied bandwidth of the macro block which does not include all or part of the area indicated by the shape input by the user during transmission can be reduced, so that compared with the traditional instant video transmission method, the method has the advantages that the required bandwidth resource is less, the bandwidth resource can be saved, the instant video transmission efficiency is improved, and the user experience is further improved.

309. And coding at least one macro block according to the first numerical value and the second numerical value to generate a coded instant video frame.

Specifically, the embodiment of the present invention does not limit the specific encoding process.

The quantization parameter of the macro block of the area indicated by the shape and not included by all or part of the user input is set to be the first numerical value, and the quantization parameter of the macro block of the area indicated by the shape and not included by all or part of the user input is set to be the second numerical value, so that the details of the area indicated by the shape and not input by the user are reserved in the encoding process, the diversified requirements that the attention degree of the user to a certain area in the instant video is higher than that of other areas, the requirements of the user to the definition and the detail reservation amount of the certain area are higher than that of other areas, and other participants of the user who want the instant video interaction migrate the attention degree to the area specified by the user are met, and the user experience is improved. Meanwhile, on the basis of carrying out undistorted transmission on the area indicated by the shape input by the user, the bandwidth occupied by the area indicated by the shape input by the user during transmission is further reduced, so that compared with the traditional instant video transmission method, the method not only can ensure the picture quality of the area indicated by the shape input by the user, but also needs less bandwidth resources, thereby saving the bandwidth resources, improving the efficiency of instant video transmission and further improving the user experience.

310. And sending the coded instant video frame.
