  • Streaming USB Webcam to YouTube Live - Raspberry Pi [migrated]

    13 mai 2016, par ysoulja

    all new here. Hoping someone can help.

    I am trying to Stream a USB webcam to YouTube Live Events but having difficulty. I followed :

    How to stream on YouTube using a Raspberry Pi ?

    I have managed to get ffmpeg compiled and can run

    ffmpeg -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video0 -c:v     libx264 -b:v 700k -an -f flv rtmp://

    It looks to me as the stream is working as I get the :

    frame= 29 fps= 29 q=28.0 12kb time=00:00.05 bitrate=1189.0kbits

    messages scrolling along however YouTube says "We are not receiving data from your encoder. Please make sure it is configured correctly in the Ingestion Settings page." While also saying "Good Health".

    Can someone please assist ? Thanks

  • How to Capture a Sequence of High-Quality PDF Frames from a Website (Without Screen Recording) ?

    9 mars, par Pubg Mobile

    In Firefox, I can take very high-quality screenshots of a webpage by using Ctrl + P and saving the page as a PDF. This method preserves the text, images, and code in excellent resolution.

    


    Now, I have created a movable bar chart race in Flourish Studio and want to convert it into a high-quality video. However, I do not want to use screen recording tools.

    


    My Goal :
    
I want to capture 30 high-resolution PDF frames from the website at different points in time (like a video sequence). Ideally, I need a tool or script that can automate the process of saving multiple PDFs from the website as it plays the animation.

    


    What I Tried :
    
I attempted to write a Python script that :

    


    Opens the local HTML file of my Flourish chart in Firefox using Selenium.
    
Waits for the page to load.
    
Listens for the F1 key and triggers Ctrl + P to print the page as a PDF.
    
However, the script does not save the PDF file in the output folder. I'm not sure why.

    


    Here is my code :

    


    import time
import keyboard
from selenium import webdriver
from selenium.webdriver.firefox.service import Service
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.firefox.options import Options

# Define paths
html_file_path = r"E:\Desktop\New folder (4)\20250309101616805.html"
geckodriver_path = r"E:\Desktop\New folder (4)\geckodriver.exe"
save_path = r"E:\Desktop\New folder (4)\New folder\output.pdf"  # Save PDF location

# Set up Firefox options
options = Options()
options.set_preference("print.always_print_silent", True)  # Silent printing
options.set_preference("print.show_print_progress", False)  # Hide progress
options.set_preference("print.print_to_file", True)  # Print to file
options.set_preference("print.save_print_settings", True)  # Save settings
options.set_preference("print.printer_PDF", "Save as PDF")  # Set printer
options.set_preference("print.print_to_file", True)  # Enable saving print output to file
options.set_preference("print.print_file_name", save_path)  # Define the save location for PDF

# Start WebDriver
service = Service(executable_path=geckodriver_path)
driver = webdriver.Firefox(service=service, options=options)

# Open the HTML file
driver.get("file:///" + html_file_path)

# Wait for the page to load
time.sleep(2)

print("Press F1 to save as PDF.")

# Listen for F1 key press
while True:
    if keyboard.is_pressed('F1'):
        print("F1 pressed, saving as PDF...")
        
        # Trigger print command (Ctrl + P)
        body = driver.find_element(By.TAG_NAME, 'body')
        body.send_keys(Keys.CONTROL + 'p')
        
        # Wait for the print dialog to process
        time.sleep(2)

        print("PDF should be saved to:", save_path)
        break

# Close browser
driver.quit()


    


    My Questions :

    


    Why is my script not saving the PDF in the specified output folder ?

    


    Is there a better way to automate capturing 30 sequential PDFs from the website at different animation frames ?

    


    Is there any tool or script that can generate a sequence of PDFs (like 30 frames per second) from a webpage ?

    


    Important :

    


    I do NOT want to use screen recording tools.

    


    I only need high-quality PDF frames that can later be converted into a video.

    


    Any help would be greatly appreciated !

    


  • How to correctly close a console application using the youtube-dl process to download Twitch stream whenever I want

    24 juin 2023, par ElPavlillo

    The test program has the following code :

    


    string url = "https://www.twitch.tv/ricoy";
string outputPath = @"D:\ruta_del_archivo_salida.mp4";

ProcessStartInfo startInfo = new ProcessStartInfo
{
    FileName = "youtube-dl",
    Arguments = $"-f best -o \"{outputPath}\" \"{url}\"",
    //RedirectStandardOutput = true,
    UseShellExecute = false,
    CreateNoWindow = true
};

using (Process process = new Process())
{
    process.StartInfo = startInfo;
    process.Start();

    //var output = process.StandardOutput.ReadToEnd();
    //process.WaitForExit();

    Console.Read();
    KillProcessAndChildren(process.Id);
}

static void KillProcessAndChildren(int pid)
{
    // Cannot close 'system idle process'.
    if (pid == 0)
    {
        return;
    }
    ManagementObjectSearcher searcher = new ManagementObjectSearcher
            ("Select * From Win32_Process Where ParentProcessID=" + pid);
    ManagementObjectCollection moc = searcher.Get();
    foreach (ManagementObject mo in moc)
    {
        KillProcessAndChildren(Convert.ToInt32(mo["ProcessID"]));
    }
    try
    {
        Process proc = Process.GetProcessById(pid);
        proc.Kill();
    }
    catch (ArgumentException)
    {
        // Process already exited.
    }
}


    


    The problem is that when I press de key in the console the youtube-dl process gets kill and also de ffmpeg but the file is left with .part extension and does not work.

    


    I was expecting the code to left a .mp4 file but for reason it does not.
