the gasket file obtaining unit is configured to execute each server in a first server cluster to obtain a first gasket file group, wherein the first gasket file group comprises a plurality of gasket files with different output formats of the same video file, the first server cluster at least comprises a first server, and the video format corresponding to the gasket signal is matched with the output format of the corresponding gasket file;
the distributed lock obtaining unit is configured to execute the first server to obtain the distributed lock of at least one gasket file in the first gasket file group, wherein one gasket file corresponds to one distributed lock;
the gasket signal output unit is configured to execute the first server to output corresponding gasket signals through corresponding gasket files according to the distributed lock, wherein one gasket file output corresponds to one gasket signal.
7. The apparatus of claim 6, wherein the pad signal output unit comprises: a first output subunit, a second output subunit, and a third output subunit;
the first output subunit is configured to execute, if the output format includes definition, outputting, by the first server according to the distributed lock, a corresponding gasket signal through a corresponding gasket file, where video definition corresponding to the gasket signal is consistent with the definition of the corresponding gasket file;
the second output subunit is configured to execute, if the output format includes a coding format, outputting, by the first server according to the distributed lock, a corresponding gasket signal through a corresponding gasket file, where a coding mode corresponding to the gasket signal matches the coding format of the corresponding gasket file;
and the third output subunit is configured to execute the step of outputting, by the first server, a corresponding gasket signal according to the distributed lock through the corresponding gasket file if the output format includes the definition and the coding format, wherein the video definition corresponding to the gasket signal is consistent with the definition of the corresponding gasket file, and the coding mode corresponding to the gasket signal is matched with the coding format of the corresponding gasket file.
8. The apparatus of claim 6, wherein the pad signal output unit comprises: a fourth output subunit;
and the fourth output subunit is configured to execute the operation that if the signal output mode set by the gasket file is a multicast mode, the first server outputs corresponding gasket signals through corresponding gasket files according to the distributed lock, wherein each gasket file is provided with a corresponding signal output mode, and the video signal output mode corresponding to the gasket signals is matched with the multicast mode.
9. A storage medium having a program stored thereon, wherein the program, when executed by a processor, implements the output method of a shim signal according to any one of claims 1 to 5.
10. An electronic device comprising at least one processor, and at least one memory, bus coupled to the processor; the processor and the memory complete communication with each other through the bus; the processor is configured to invoke program instructions in the memory to perform the method of outputting a shim signal as claimed in any one of claims 1 to 5.
