Download Wistia videos in a Teachable course to be able to watch offline

README.md

Go to your teachable course and show the page where videos are.

Now open your Browser's console. For example in Chrome you can press F12 to open it.

Paste the following code in the console

$('.attachment-wistia-player').each(function () { console.log($(this).attr('data-wistia-id')); });

Press enter to retrieve all videos IDs that are present in the opened page. For example:

myid1
myid2
myid3

Paste the list of videos ids to download in a file ids.txt

Lunch the provided wistia-downloader.py with the command line:

python3 wistia-downloader.py

This will read the videos IDs from the file ids.txt and it will download the videos in the current directory

wistia-downloader.py

import requests
import re
import json
import urllib.request

ids = open('ids.txt').read().split('\n')

num = 0
for wid in ids:
	r = requests.get('https://fast.wistia.net/embed/iframe/' + wid, allow_redirects=True)
	content = str(r.content).replace('\\\'', '') \
	                        .replace('\\\\"', '') \
	                        .replace('\\', '')
	rs = re.search("iframeInit\((.*?)\);", content)
	f = open('debug.json', 'w')
	f.write("[" + rs.group(1) + "]")
	f.close
	json_config = json.loads("[" + rs.group(1) + "]")
	filename = '{:02d}'.format(num) + ' - ' + json_config[0]['name']
	assets = json_config[0]['assets']
	max_size = 0
	link_with_max_size = 'NONE'
	for a in assets:
		if a['size'] > max_size:
			max_size = a['size']
			link_with_max_size = a['url']
	print('downloading ' + filename)
	urllib.request.urlretrieve(link_with_max_size, filename)
	print('download complete\n')
	num += 1

it doesn't work
