Referring to fig. 1, an embodiment of the present invention provides a line switching control method, which is suitable for a screen-casting operation of a live broadcast mobile terminal at a television terminal, and includes:
s1: a status lock function castingLock of an atomic variable type is defined, and a lock function and an unlock function are defined for the status lock function.
The screen projection is a time-consuming process, and when the screen projection for the first time is not completed, the switching operation of the screen projection for the second time is performed, so that unfriendly interactive experience is brought to a user. In the embodiment of the invention, the state lock function is an atomic variable, and the atomic variable is thread-safe in java, so that the abnormal condition can not occur when a plurality of threads operate the state lock function.
In the traditional scheme, the maintenance of the synchronization state when the live broadcast mobile terminal and the television terminal screen cast is changed by using a global variable, but the synchronization state is managed by using the global variable, so that the defects are that firstly, threads are unsafe, namely, the state is disordered when multi-thread operation is carried out, so that the state maintenance is wrong; secondly, the maintenance is complex, and programmers need to spend more time and energy to manage and maintain the synchronous state, so that the waste of human resources is caused; thirdly, due to the difficulty of maintenance, bug with abnormal state is easily introduced, so that the program is not robust enough and the effective and correct execution of the program cannot be ensured.
S2: in the screen projection operation process, a lock function is called to lock the state lock function, and after screen projection is completed, an unlock function is called to unlock the state lock function. For lock and unlock operations of the state lock function: carrying out setting value operation on the atomic variable to realize locking operation on the state lock function; and clearing the value set by the atomic variable to realize the unlocking operation of the state lock function. And when the locking operation is carried out on the state lock function, whether the atomic variable is set or not is judged, if yes, the locking fails, and at the moment, an error message, namely, the lock fails, is returned. Similarly, for unlocking the state lock function, the unlock function clears the value of the atomic variable, and the unlock function clears the atomic variable no matter whether the atomic variable is set with the value or is empty. The screen projection operation process refers to the process from the screen projection start to the screen projection end.
Through the steps, the whole screen projection process is mapped to the state lock function, and the current state condition can be acquired through the state lock function in the later stage when the switching operation of the line is carried out.

In the conventional scheme, the switching of the lines is performed through a global variable, when different lines are selected, the global variable is changed into corresponding line information, and thus state information can be acquired through the global variable.
In an embodiment, when switching lines, after judging that the state lock function is in an unlocked state, the states of all lines are set to be in an unselected state, and then a target line is set to be in a selected state, and if switching is performed from a line 1 to a line 2, the states of all lines are set to be in the unselected state, and then the state of the line 2 is set to be in the selected state, so that switching of the lines is completed.
When the definition of the live-broadcast watching picture is switched, the screen projection operation is carried out again after the definition switching is finished, and different video sources are obtained in principle by switching the definition, so that a method similar to the line switching control method of the embodiment of the invention can be used for synchronizing the definition switching and the screen projection operation.
According to the line switching control method, through the definition of the state lock function, when screen projection operation is carried out between the live broadcast mobile terminal and the television terminal, the lock function is called to carry out locking operation on the state lock function, after the screen projection operation between the live broadcast mobile terminal and the television terminal is completed, the unlock function is called to carry out unlocking operation on the state lock function, mapping between the state lock function and the screen projection process is achieved, if the screen projection operation is carried out currently, the state lock function is in a locking state, processing is not carried out at the time, and therefore the line switching operation cannot be carried out any more when the screen projection operation is carried out, synchronization of the line switching operation and the screen projection operation state is guaranteed, and good interactive experience is brought to a user.
