Abstract

The invention provides a screen projection method and device and a storage medium. The method is applied to a screen projection sending end provided with a screen projection application, and in a screen projection scene, audio equipment currently used by the screen projection sending end is acquired, and an identification number corresponding to the audio equipment is recorded in an audio state table, so that when it is determined that sound output equipment selected by a user is a screen projection receiving end, the audio output equipment can be automatically output. And the audio data is acquired from the audio equipment identified by the identification number and is sent to the screen projection receiving end for playing instead of default audio equipment, such as a loudspeaker, so that the screen projection receiving end can always acquire the audio data and then play sound when the screen projection receiving end is sound production equipment in the screen projection process.

Description

technical field [0001] The present application relates to the technical field of screen projection, and in particular to a screen projection method, device and storage medium. Background technique [0002] With the development of terminal technology, more and more terminals have screen projection functions. For example, in family, work, teaching, and game competition scenarios, terminals can greatly facilitate people to watch by projecting the currently displayed screen onto a large screen. screen content. [0003] For the screencasting sender, that is, the terminal that sends the screencasting information is a personal computer (PC device) screencasting scene. At present, it is necessary to use the screencasting application installed on the PC device to realize the audio and video played on the PC device. The content is projected to the projection receiving end, such as TV and other large-screen devices (subsequently referred to as large-screen devices). [0004] Although...
