This is particularly important for machines with weak CPUs or when using multiple tuners in one system. Greatly reduced load on the entire machine (with certain technical caveats).These cards, currently the Hauppauge PVR cards, the AVerMedia M179 and any other card which supports the V4L2 MPEG Encoder API, have a video processor on-board which compresses the tuned video signal into an RTjpeg, MPEG-2, or MPEG-4 program stream before sending it into the computer. MPEG-4 is particularly demanding for systems with weaker CPUs, RTjpeg consumes less CPU time at the cost of larger file sizes and more digital video artifacts. Depending on your encoding settings, you may need close to 1GHz of CPU speed to handle a single encoding stream, and more if you have multiple cards or want to play back while recording. The main disadvantage of this type of card is the high CPU requirements. If you have the CPU power, MPEG-4 produces better quality with smaller file sizes than the MPEG-2 used with most hardware encoding cards.High flexibility - you can choose your encoding method and employ filters prior to encoding.These cards deliver an unencrypted data stream to MythTV, which then encodes to MPEG-4 or RTjpeg using software encoders. If you do not give a valid YouTube URL in your command-line argument, the script will prompt you to enter one.These cards (also called frame grabbers and software encoders) are usually based on a chipset like the Bt848/878 or Conexant cx2388x, and decode broadcast NTSC, PAL, or Secam television. Run the ytd.py Python script followed by the URL of a video you wish to download. However, the first time you run the script with them on, Google will ask you to register your device (see below), which is free and takes about 30 seconds.Ĥ. You can try running the script without these, but in my experience, it will not download videos if these are not enabled. On line 7, you'll note that we are downloading our YouTube video with oauth and oauth caching enabled. If there's no argument given at the command line or the argument doesn't contain a YouTube URL, it prompts the user to paste in a YouTube URL and then downloads it in MP4 format, using the title of the video (with dashes for spaces) as the filename. It creates a blank variable called videoURL and, if there's an argument given at the command line, it checks to see if that URL contains. It first imports YouTube from pytube and sys (needed for handling command-line arguments). This is a very simple script that could be even simpler. Yt.streams.first().download(filename=filename + ".mp4") Print("Downloading YouTube File: " + yt.title) Yt = YouTube(videoURL,use_oauth=True,allow_oauth_cache=True) Create the following Python script and save it as ytd.py or whatever you want to name it. If you're using Windows, you can get Python, which includes pip, from Ģ. Install Python and pip if you don't have them both already. The following steps will work for Windows, Linux and (likely) macOS as well.ġ. You just need to have a recent version of Python installed and be comfortable working with the command line. If you want a YouTube download process that involves fewer steps, using a Python script with pytube, a free Python library, is a great way to do it. How to Download YouTube Videos Using Python Within a few seconds or minutes, depending on the file size and Internet connection, you'll have an MP4 of the YouTube video stored locally.
