Is it possible to stream chunks from a mpegts video file to VLC Player if so, then how I can format UDP packets in MPEG-TS format?

I’m actively looking for a thorough explanation of the underlying structure within MPEG-TS encoded UDP packets because my project uses VLC Player to transmit MPEG-TS video over UDP. My goal is to fully comprehend the complex structure of these UDP packets that include MPEG-TS content, including the headers and data segments.
The effective completion of my project depends on this information, thus I’m keen to understand the technical nuances involved. I need a detailed explanation of the MPEG-TS encoded UDP packets’ structure. The technical knowledge and skills in this subject are highly regarded and essential to the development of my project.

Yes, it is possible to stream segments of an MPEG-TS (MPEG Transport Stream) video file to a VLC Player using UDP. A popular video streaming format, particularly across networks, is MPEG-TS. To achieve accurate packetization and transmission, precise standards must be observed while formatting UDP packets for the MPEG-TS structure.

Here is a general guide for configuring MPEG-TS video file chunk streaming via UDP to VLC Player:

1. Make the video file ready.

  • Verify that the MPEG-TS encoding on your video is active. If you need help, you might need to use the appropriate software to convert it to MPEG-TS format.
  • Organize your video into manageable chunks, sometimes known as segments or packets. These chunks will be transmitted as separate UDP packets.

2. UDP Packet Formation

  • The MPEG-TS standard separates the content into fixed-size packets called transport packets or TS packets.
  • Each TS packet has an exact size of 188 bytes and is made up of a 4-byte header and 184 bytes of content.
  • A packet identifier and synchronization data are both contained in the header.
  • Packetize your video content into these TS packets accurately.

3. Transmission of UDP Packets

  • Use a specialist streaming tool or a computer language like Python to send the TS packets via UDP.
  • In Python, you may create and send UDP packets using modules like Socket. Each packet should contain TS packet data.

Here is an example of how to use Python to deliver MPEG-TS packets over UDP:

import socket

# Configure UDP connection
udp_ip = ""  # Destination IP address (VLC player's IP)
udp_port = 1234      # Destination UDP port
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# Read and dispatch TS packets
with open("segment1.ts", "rb") as ts_file:
    while True:
        ts_packet =  # Read 188 bytes (one TS packet)
        if not ts_packet:
        sock.sendto(ts_packet, (udp_ip, udp_port))


4. VLC Player Setup

  • Open VLC Player\
  • Navigate to Media > Open Network Stream.
  • Input the UDP stream URL in this pattern: udp://@:1234, where 1234 represents the UDP port used for packet transmission.

It should be noted that this is a simplistic example and those real-world situations would include error handling, appropriate synchronization, and possibly more sophisticated streaming features, such as managing numerous segments and adjusting playback timelines.
