Record and replay UDP streams

UDPRecorder

UDPRecorder is a Python library for recording and replaying UDP steams. It is made to ease the development of applications based on UDP streams. It is originally used to replay telemetry data from sim racing games such as Assetto Corsa Competizione or F1 20XX games.

Installation

Use the package manager pip to install UDPRecorder.

pip install udprecorder

Usage

Commandline

record_udp -p 1234 -s 127.0.0.1 -f myfile.bin -b 1024 -c 9999 -s 3600
replay_udp -p 1234 -s 127.0.0.1 -f myfile.bin

		description	required	type	default
-p	--port	Port to listen/replay to	False	int	1234
-s	--server	Host to listen/replay to	False	str	127.0.0.1
-f	--file	File to save/read the stream	False	str	udp.bin
-b	--buffer	Buffer size limit	False	int	65536
-c	--count	number of message to read	False	int	1000000000
-t	--time	time limit to record	False	int	1000000000

In scripts

import udprecorder

# To record a stream
udprecorder.record(
    file_name = 'my_record.bin', # path to the saved replay
    addr = ('127.0.0.1', 1234)   # (host, port) to listen to
    buffer_size = 65536     # size of buffer used for the socket
    max_num_packets = 1200  # stop the record after 1200 event received
    max_seconds = 3600      # stop the record after 1 hour
)

# To replay a stream
udprecorder.replay(
    file_name = 'my_record.bin', # path to the saved replay
    addr = ('127.0.0.1', 1234)   # (host, port) to emit to
)
