Proxy Insecure

In video editing, the term "proxy" refers to the use of duplicate video with reduced resolution, which allows you to edit even on weak computers. The Adobe Premiere application itself does not allow you to set up a proxy connection.

In Windows, proxy settings for local connections are made through the "Network and Sharing Center" (from the "Control Panel"). You need to select "Browser Properties", then go to "Connections" and click on "Network Setting". And there you can set either the script or the parameters for the proxy.

In UDP, there is no built-in mechanism to know the size of an incoming packet before receiving it. The UDP protocol is a connectionless protocol, meaning it does not establish a connection between the sender and receiver before sending data. This makes UDP fast and efficient but also means that the receiver has no way to know the size of the incoming packet in advance.

When you receive a UDP packet, you can determine its size by examining the received data. In most programming languages, you can access the received data as a byte array or buffer. The size of the packet can be calculated by finding the length of the received data.

For example, in Python, you can use the recvfrom() function to receive a UDP packet and the len() function to calculate its size:

import socket

# Create a UDP socket
server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# Receive a UDP packet
data, address = server_socket.recvfrom(1024)

# Calculate the size of the received packet
packet_size = len(data)

print(f"Received packet of size: {packet_size} bytes")

In this example, the recvfrom() function receives a packet up to 1024 bytes in size, and the len() function calculates the length of the received data, which is the size of the packet.

Keep in mind that the maximum size of a UDP packet is limited by the maximum transmission unit (MTU) of the underlying network, which is typically 1500 bytes. However, it's always a good idea to handle cases where the received packet size exceeds your expectations, as this may indicate a packet fragmentation issue or an error in the communication.

Technically, a proxy is an ordinary computer or server connected to a network (local or Internet). It accepts traffic from the user, redirects it to the address that was specified in the request. And then receives the response from the server and transmits it to the user's equipment. That is, it is actually an intermediary.

First you should check if its characteristics are correct. Some proxy servers are just IP address and port number, others use so called "connection script". You need to double-check that the data was entered correctly.
