  • extracting video and data streams from MPEG2 TS over RTP in real-time

    10 January 2024, by Tejal Barnwal

    I have H264 video stream and KLV meta data encapsulated inside MPEG2 TS container which are sent over an RTP over UDP from a camera.
I intend to do the following:

    


      

    1. Extract both video and data streams from RTP

      2. 


    2. Process video feed using opencv in a seperate thread

      3. 


    3. process klv metadata in a seperate thread

      4. 


    


    My problem what exact arguments should I provide to ffmpeg so as to read h264 video stream and show the images frame by frame using opencv?

    


    With the help of some previous posts like Simultaneously map video and data streams to one subprocess pipeline in real-time, I was able to get some idea about how could I proceed to procees the stream over RTP.

    


    I started out by using the following script:

    


    #!/usr/bin/env python3
from asyncio import streams
from logging.handlers import QueueListener
import klvdata
import subprocess as sp
import shlex
import threading
import numpy as np
import cv2
import time
from io import BytesIO

# Video reader thread.
def video_reader(pipe):
    cols, rows = 1280, 720  # Assume we know frame size is 1280x720

    counter = 0
    while True:
        print("read image")
        raw_image = pipe.read(cols*rows*3)  # Read raw video frame

        # Break the loop when length is too small
        if len(raw_image) < cols*rows*3:
            break

        if (counter % 10) == 0:
            # Show video frame evey 60 frames
            image = np.frombuffer(raw_image, np.uint8).reshape([rows, cols, 3])
            cv2.imshow('Video', image) # Show video image for testing
            cv2.waitKey(1)
        counter += 1
        print("image showed on window")
        time.sleep(0.25)



# https://github.com/paretech/klvdata/tree/master/klvdata
def bytes_to_int(value, signed=False):
    """Return integer given bytes."""
    return int.from_bytes(bytes(value), byteorder='big', signed=signed)


# Data reader thread (read KLV data).
def data_reader(pipe):
    key_length = 16  # Assume key length is 16 bytes.

    f = open('data.bin', 'wb')  # For testing - store the KLV data to data.bin (binary file)

    while True:
        # https://en.wikipedia.org/wiki/KLV
        # The first few bytes are the Key, much like a key in a standard hash table data structure.
        # Keys can be 1, 2, 4, or 16 bytes in length.
        # Presumably in a separate specification document you would agree on a key length for a given application.
        key = pipe.read(key_length)  # Read the key
        
        if len(key) < key_length:
            break  # Break the loop when length is too small
        f.write(key)  # Write data to binary file for testing

        # https://github.com/paretech/klvdata/tree/master/klvdata
        # Length field
        len_byte = pipe.read(1)

        if len(len_byte) < 1:
            break  # Break the loop when length is too small
        f.write(len_byte)  # Write data to binary file for testing

        byte_length = bytes_to_int(len_byte)

        # https://github.com/paretech/klvdata/tree/master/klvdata                                                
        if byte_length < 128:
            # BER Short Form
            length = byte_length
            ber_len_bytes = b''
        else:
            # BER Long Form
            ber_len = byte_length - 128
            ber_len_bytes = pipe.read(ber_len)

            if len(ber_len_bytes) < ber_len:
                break  # Break the loop when length is too small
            f.write(ber_len_bytes)  # Write ber_len_bytes to binary file for testing

            length = bytes_to_int(ber_len_bytes)

        # Read the value (length bytes)
        value = pipe.read(length)
        if len(value) < length:
            break  # Break the loop when length is too small
        f.write(value)  # Write data to binary file for testing

        klv_data = key + len_byte + ber_len_bytes + value  # Concatenate key length and data
        klv_data_as_bytes_io = BytesIO(klv_data)  # Wrap klv_data with BytesIO (before parsing)

        # Parse the KLV data
        for packet in klvdata.StreamParser(klv_data_as_bytes_io): 
            metadata = packet.MetadataList()
            for key, value in metadata.items():
                print(key, value)
                
            print("\n") # New line

# Execute FFmpeg as sub-process
# Map the video to stderr and map the data to stdout
process = sp.Popen(shlex.split('ffmpeg -hide_banner -loglevel quiet '                        # Set loglevel to quiet for disabling the prints ot stderr
                               '-i "rtp://192.168.0.141:11024" '                                        # Input video "Day Flight.mpg"
                               '-map 0:v -c:v rawvideo -pix_fmt bgr24 -f:v rawvideo pipe:2 ' # rawvideo format is mapped to stderr pipe (raw video codec with bgr24 pixel format)
                               '-map 0:d -c copy -copy_unknown -f:d data pipe:1 '            # Copy the data without ddecoding.
                               '-report'),                                                   # Create a log file (because we can't the statuses that are usually printed to stderr).
                                stdout=sp.PIPE, stderr=sp.PIPE)


# Start video reader thread (pass stderr pipe as argument).
video_thread = threading.Thread(target=video_reader, args=(process.stderr,))
video_thread.start()

# Start data reader thread (pass stdout pipe as argument).
data_thread = threading.Thread(target=data_reader, args=(process.stdout,))
data_thread.start()


# Wait for threads (and process) to finish.
video_thread.join()
data_thread.join()
process.wait()



    


    With the above script, I was facing two issues:

    


      

    1. The second thread resulted in an attribute error

      2. 


    


    Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/lib/python3.8/threading.py", line 932, in _bootstrap_inner
    self.run()
  File "/usr/lib/python3.8/threading.py", line 870, in run
    self._target(*self._args, **self._kwargs)
  File "video_data_extraction.py", line 97, in data_reader
    print(packet.MetadataList())
AttributeError: 'UnknownElement' object has no attribute 'MetadataList'



    


      

    1. With this though I continuously able to see following output on the terminal regarding reading the images

      2. 


    


    read image
image showed on window
read image
image showed on window
read image
image showed on window
read image
image showed on window
read image
image showed on window
read image
image showed on window


    


    The imshow windows wasnt updating properly! It seemed stuck after a few frames.

    


    Further diving into the lane with the help of following command, I concluded that the video stream that I am reading has H264 encoding

    


    ffprobe -i rtp://192.168.0.141:11024 -show_streams -show_formats


    


    Output of the above command:

rtp://192.168.0.141:11024: corrupt input packet in stream 0
frame=  124 fps=2.6 q=-0.0 size=  334800kB time=00:00:05.32 bitrate=515406.0kbits/s dup=97 drop=0 speed=0.111x 


    


    What arguments do I provide to ffmpeg and in what order because my stream 0 is metadata and stream 1 is video so as to display image frame by frame with opencv?
I would be grateful for any help that you could provide.

    


    Further, I also have a query regarding how does ffmpeg know to that it has to first convert the rtp packets into mpeg2 TS packets before segregating video stream and data stream?

    I'm trying to use ffmpeg in order to transcode RTSP stream from CCTV to HLS stream so it could be accessed through a web server.

    


    ffmpeg used to stream video from CCTV with following command

    


    $ ffmpeg -i "rtsp://cam-1.loc:554?user=admin&password=admin&channel=1&stream=0" -hls_time 3 -hls_wrap 10 -f mpegts udp://localhost:6601

    Why nmap do not see that UPD port is open?

    


  • ffmpeg command not working from bash script but working from command line [duplicate]

    6 October 2023, by SamTech

    I wrote a bash script that is generating command to encode video and create HLS playlist.

    


    Here is the script. To make it short and clear, i fill variables with hard-coded values.

    


    #!/bin/bash

# below variables are generated from some other script
