Task:

Write a server in Java so that it performs the following functions:
- listens to port 554
- allows VLC Player to connect - y via RTSP protocol
- sent traffic to VLC player via UDP protocol, reading it from pcap-dump.
- as a result, the VLC player should play the video that the server sends from the
dump
- the server should work under Linux
Result - the player should play the data that the server sends.

Answer 1

The task consists of two and a half:

1. Read stream from Pcap file https://www.javahelps.com/2017/08/parse-pcap-files...
   
2. Generate RTSP stream from read Pcap https://www.oracle.com/java/technologies/javase/ja... or https://netty.io/
   

2.5 step - the union of these two.
ps there are options without Java - play pcap with tcpreplay and form the necessary stream with ffmpeg
