PYTHON – Script to download youtube videos for offline viewing

I was interested in viewing this video of a news conference (USENIX 2016) on my trip home on Metro North Train, NYC => CT. The trip is about an hour an 10 minutes from Manhattan’s Grand Central Terminal to Milford CT, express train that is. My concern was that I would have choppy internet service on the way since I recently updated my laptop and the built in Verizon Mobile card was not activated yet. I would need to use my ATT iPhone as a hotspot, which proved to be very shakey at times. A colleague of mine recommended a website for making youtube videos available for offline viewing. The name of this site was:

http://www.keepvid.com

Right off the rip I was concerned that this site was infested with malware and any other bullshit associated with a free video ripping service. I used the site and was able to create a download of the video I was interested in, however who knows how sick my Windows based machine just got. I could of contracted anything from this site.

I thought about this and said, there has to be a better way, or a python lib for this, and low and behold a search came up with PYTUBE:

This library had some interesting features and literally blew away the keepvid site in regards to flexibility. Here is some explaining of what this library can do. Please have a look at the examples below, I will do my best to narrate them.

Here I use PIP to install the PYTUBE lib, you can ignore the DEPRECATION: warning for my outdated python that blares at you for being such an idiot.

Next up you can see that I am setting a variable yt(this is the video you want to download). Using python’s Pretty Print Lib you can run the pprint(yt.get_videos() method to see what formats are available for download.

Please have a look at the comments in the code for a bit more details in regards to what is going on, in this example I am using the filename Pulp_Fiction.mp4 for my filename I want to be when downloaded.

Ok so here is what it looks like when you execute the program:

As you can see we have a new filename with the video we asked for to watch without a streaming internet connection, here is a ls to show:

As always, I am sure there are better ways to do this and I am sure there is cleaner code. Most of this code was taken right from the authors site who is a badass, here is his link:
