[0005] During the desktop live broadcast process of the terminal, the terminal user can only see the activities of the live broadcast area from the desktop of the terminal itself, but cannot view the live broadcast area from the perspective of the viewer. Once the size of the live broadcast area is not set properly, the adjustment process It is also impossible to watch the adjustment results of the live broadcast area in real time, resulting in poor desktop live broadcast effect

[0062] During the adjustment operation, whenever the terminal detects that the execution time of the adjustment operation reaches a preset time length, the terminal acquires the live broadcast area when the preset time length is reached. For example, take the preset duration of 2 seconds as an example. During the adjustment operation, the terminal obtains the adjusted live broadcast area every 2 seconds. If the entire adjustment operation takes a long time, you can Real-time acquisition and adjustment of live broadcast areas corresponding to different stages, and by setting the preset duration, frequent processing of desktop screenshots can be avoided, and pressure on the operation of the terminal can be avoided.
[0063] During the adjustment operation, whenever the terminal detects that the movement distance of the adjustment operation reaches the preset distance, it acquires the live broadcast area when the preset distance is reached. For example, take the preset distance o...

The invention discloses a previewing method and device based on desktop live broadcast, and belongs to the technical field of the network. The previewing method based on desktop live broadcast comprises the steps of (1) carrying out screenshot operation on a current desktop in the process of desktop live broadcast when an adjustment operation carried out on a current live broadcast zone is detected, obtaining a desktop screenshot, (2) obtaining an adjusted live broadcast zone according to the adjustment operation, (3) generating a previewing image of the adjusted live broadcast zone according to the desktop screenshot and the live broadcast transmission resolution when the size of the adjusted live broadcast zone is larger than the live broadcast transmission resolution, and (4) displaying the previewing image on the basis of a desktop. According to the previewing method and device based on desktop live broadcast, the previewing image of the adjusted live broadcast zone is displayed according to the relation between the size of the adjusted live broadcast zone and the live broadcast transmission resolution, a terminal carries out real-time display on previewing images corresponding to live broadcast zones adjusted in different stages in the whole process of adjustment, a user can serve as a viewer to preview and watch the adjustment result of the live broadcast zones in real time, and the effect of desktop live broadcast is ensured.
Description
technical field [0001] The invention relates to the field of network technology, in particular to a preview method and device based on desktop live broadcast. Background technique [0002] With the development of network technology, people can use mobile phones, computers and other terminals to not only transmit and share data, make video calls, etc., but also live broadcast the desktop activities on the terminal desktop, and share the use process of the terminal with the other party. [0003] During desktop live broadcast, the live broadcast area of the terminal is limited to the determined live broadcast area on the terminal desktop, and viewers can only see the live broadcast area played by the terminal when watching the desktop live broadcast. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] During the desktop live broadcast process of the terminal, the terminal use...
