    Oh, Im sorry. If I’m honest I completely forgot. Here it is:

    You will need ffmpeg installed, and I did write it for Linux, so I’m not sure if there are differences for windows. Worst case you need to slightly modify it to work on windows.

    #!/usr/bin/env python3

import subprocess

    """
    Downloads video chunks from the given base URL and merges them into a single file.

    :param base_url: The URL to the playlist or base directory containing the video chunks.
    :param output_file: The name of the output video file (e.g., "output.mp4").
    """
    try:
        # Get the playlist file (e.g., .m3u8 or .ts index file)
        print(f"Fetching playlist or video chunk URLs from: {base_url}", flush=True)
        response = requests.get(base_url, timeout=10)
        response.raise_for_status()
        
        # Parse the playlist to get the chunk URLs
        lines = response.text.splitlines()
        chunk_urls = [urljoin(base_url, line) for line in lines if line and not line.startswith("#")]

        if not chunk_urls:
            print("No video chunks found in the provided URL.", flush=True)
            return

    download_video_chunks(base_url, output_file)

    If you guys can recommend a fair and open pastebin alternative for me I will upload it there as well and edit this with the link

  • @promitheas@programming.devOPtoLinux@lemmy.ml•Ubuntu Dapper Drake virtio package needed to set up networking in the VM
    1•3 months ago

    I considered that, and the reason I decided to go with the method I chose was twofold:

    1. I of course need to be safe - that means I don’t want to run unsafe kernel code on my main machine, so a virtual machine makes sense. I could use one of my old laptops as both a host and target machine, but honestly I have my main machine set up just how I like it for development so I would probably end up using it for writing the actual code anyway. I suppose I could have one of my laptops be the target and pull code from github (exactly what I was planning to do with the virtual machine just with real hardware).

    2. I didn’t want to introduce more problems than would naturally occur when going through the book while learning, by adding the fact that I have a great mismatch in kernel versions, which would undoubtedly change the APIs a great deal. I learn better when I can focus on getting comfortable with one thing at the beginning, and then building from there. If its not as tragic as I imagine it though (the mountain looks larger before you start the climb) I would definitely prefer getting comfortable with the modern kernel as ultimately that’s what I plan to develop on (this all started because I want to fix some stuff with my Genesis Xenon 770 mouse that I’m unhappy with currently).

    However, I am open to the idea. Could you direct me to any resources you found helpful specifically for adapting what you read/learn in that book, to the modern kernel? Or any other helpful resources really, anything would be helpful at this point. Discords, forums, wikis, whatever you have :)
