How can I read a file (video, any) in one line and send it via a socket to a client.?

Question

Java

On the server I read the file in ONE LINE . I read line by line. I replace all newlines and send to the client, the client restores the newlines and saves the file on his machine. The problem appears with the encoding, when transferring a picture or video, the file is displayed in a different encoding. How to solve this problem, how to determine the file encoding, or you can somehow without encoding, for example, compress the file into an archive.
And is it correct to read the file line by line using BufferedReader fr=new BufferedReader(new FileReader(file))
