Remarks

Whether the third parameter in this interface needs to enter a value depends on the control command. In the NET_SDK_PLAYSETPOS command, this parameter indicates the playback progress. When the control command is to start playing, the value of the third parameter indicates the offset of the current file. If the value is 0, it means playing from the beginning of the file. If the value is not 0, it indicates the file position (Byte) of the breakpoint resume. The fourth parameter in this interface indicates the corresponding parameter obtained by the current control command operation.
