• AttributeError : 'FilterableStream' object has no attribute 'input' - ffmpeg-python

  26 septembre 2024, par Karolek

  I am a fresh programmer and I am learning the Python language.
I have been trying to design a graphical application (using tkinter and ffmpeg-python libraries) that converts an image file along with audio into a video of audio length displaying the image. Unfortunately whenever I try run program I keep encountering errors

  


  At first it was due to installing the ffmpeg library in pip package manager instead of ffmpeg-python. I uninstalled the previous one, installing the correct one making sure no other package causes problems. Using a short script like this, the library functioned smoothly :

  


  '''
The Error causing Statement
import ffmpeg 
(
    ffmpeg.input("something.mp3")
    .output("output.wav")
    .run()
)
'''
# When I tried to use the ffmpeg library in a graphics program within a function, unfortunately I was not able to get it to work

import tkinter as tk
from tkinter import filedialog
from tkinter import ttk

def select_image():
    file_path = filedialog.askopenfilename(title="Select a file", filetypes=[("image files","*.jpg;*.png;*.gif;*.jfif;")])
    print("Selected file:", file_path)

def select_audio():
    file_path = filedialog.askopenfilename(title="Select a file", filetypes=[("audio files","*.mp3;*.wav;*.ogg;*.flac;*.m4a;*.acc;")])
    print("Selected file:", file_path)

def create_video(image_file, audio_file, output_format):
    import ffmpeg
    (
        ffmpeg.input(image_file, loop=1)
        .input(audio_file)
        .output("output" + output_format)
        .run()
    )   

def choose_directory():
    directory_path = filedialog.askdirectory(title="Select directory")
    print("Selected directory:", directory_path)


root = tk.Tk()

root.title("Audio To Video Converter")
root.geometry("500x700")

title = tk.Label(root, text="Audio To Video Converter", font=('Arial', 28))
title.pack(padx=20, pady=20)

selectImage_button = tk.Button(root, text="Select image", command=select_image, height=3, width=50)
selectImage_button.pack(pady=10, padx=20)
selectAudio_button = tk.Button(root, text="Select audio", command=select_audio, height=3, width=50)
selectAudio_button.pack(pady=10, padx=20)

label1 = tk.Label(root, text="Output video format", font=('Arial', 16))
label1.pack(padx=20, pady=10)

outputFormat = ttk.Combobox(root, width=55)
outputFormat['values'] = ('.avi', '.mkv', '.mp4', '.webm')
outputFormat['state'] = 'readonly'
outputFormat.pack(pady=5, padx=20)

label2 = tk.Label(root, text="Output directory", font=('Arial', 16))
label2.pack(padx=20, pady=10)

outputDirectory_button = tk.Button(root, text="Select directory", command=choose_directory, height=3, width=50)
outputDirectory_button.pack(pady=5, padx=60)


convert_button = tk.Button(root, text="Convert", height=3, width=50, command=create_video(selectImage_button, selectAudio_button, outputFormat['values'] ))

root.mainloop()


  


  This is the only thing the console displayed after attempting to run

  


  Traceback (most recent call last):&#xA;  File "c:\Users\Admin\Documents\konwerter\konwerter.py", line 56, in <module>&#xA;    convert_button = tk.Button(root, text="Convert", height=3, width=50, command=create_video(selectImage_button, selectAudio_button, outputFormat[&#x27;values&#x27;] ))&#xA;                                                                                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^&#xA;  File "c:\Users\Admin\Documents\konwerter\konwerter.py", line 17, in create_video&#xA;    .input(audio_file)&#xA;     ^^^^^&#xA;AttributeError: &#x27;FilterableStream&#x27; object has no attribute &#x27;input&#x27;&#xA;</module>

  


  I did some research and did not find any information about this error except that it may be due to installing the wrong libraries. This is my list of installed libraries in pip package manager :

  


  colored           2.2.4 customtkinter     5.2.2 darkdetect        0.8.0 ffmpeg-python     0.2.0 future            1.0.0 Gooey             1.0.8.1 packaging         24.1 pillow            10.4.0 pip               24.2 psutil            6.0.0 pyee              12.0.0 pygtrie           2.5.0 six               1.16.0 tkinterdnd2       0.4.2 typing_extensions 4.12.2 wxPython          4.2.2


  


  Perhaps the solution to the problem is simple, but I am new and don't understand many things. I will be very grateful for your answer !

  


• Understanding User Flow : Eight Practical Examples for Better UX

  4 octobre 2024, par Daniel Crough — Analytics Tips, UX

  Imagine trying to cook a complex dish without a recipe. You might have all the ingredients, but without a clear sequence of steps, you’re likely to end up with a mess rather than a masterpiece. Similarly, designing a website without understanding user flow is a recipe for confusion and lost conversions.

  User flows—the paths visitors take through your site—are the recipes for digital success. They provide a clear sequence of steps that guide users towards their goals, whether that’s making a purchase, signing up for a newsletter, or finding information. By understanding and optimising these flows, you can create a website that’s not just functional, but delightfully intuitive.

  In this article, we’ll explore seven practical user flow examples and show you how to apply these insights using web analytics tools. Whether you’re new to user experience (UX) design or a seasoned professional, you’ll find valuable takeaways to enhance your digital strategy.

• Stream H264 raw data on RTSP server

  1er janvier, par Aitazaz

  I have H264 hex string data saved in a list.
The data is in correct format as it is being received, I am trying to stream it to RTSP server.

  


  I have stream the data in realtime as it is from a dashcam.

  


  The RTSP server is deployed but when I stream frames to it, the connection is created and then ends in an instant (does not last for a second)

  


  The code is mentioned below which performs this streaming task.

  


  def h264_stream_to_rtsp(data_list, rtsp_url):
    try:
        ffmpeg_command = [
            "ffmpeg", 
            "-f", "h264",
            "-i", "-",
            "-vcodec", "libx264",
            "-preset", "fast",
            "-f", "rtsp",
            "-analyzeduration", "5000000",
            "-probesize", "5000000", 
            rtsp_url  # The RTSP URL to stream to
        ]
        
        ffmpeg_process = subprocess.Popen(ffmpeg_command, stdin=subprocess.PIPE)

        for index, hex_data in enumerate(data_list):
            # print(f"Processing hex data {index + 1}/{len(data_list)}...")

            if len(hex_data) % 2 != 0:
                hex_data = '0' + hex_data  # Append a leading zero if length is odd

            binary_data = binascii.unhexlify(hex_data)

            ffmpeg_process.stdin.write(binary_data)

        ffmpeg_process.stdin.close()

        ffmpeg_process.wait()
        print("Stream completed.")

    except KeyboardInterrupt:
        print("Stopping live stream.")
    except Exception as e:
        print(f"Error: {e}")


  


  Logs from the RTSP server are mentioned below :

  How can I stream continuously ?
