Extracts links to all lessons for others to fetch with curl later
Well, I needed to give a few links of interesting coursera videos to my friend. The problem was that course already ended and he couldn't see videos. Luckily, auth/enrollment is not required to watch the video if you know the direct link to .mp4. For not to dig for those links manually in firebug, I wrote this small script.
Ok, ok. I didn't write it right away. I tried to search for something already existing, found https://github.com/coursera-dl/coursera and https://gist.github.com/macias/2880753, but first was too big and the second was too php :)
You can feed the tool with any coursera's class link - like https://www.coursera.org/course/hwswinterface or https://class.coursera.org/digitalmedia-002/lecture/79 - it will find all the needed stuff by itself
In true UNIX style, it doesn't copy functionality of other's tools, just extracts urls. If you want to download actual .mp4 files - with continuation/in proper folders/on other PCs, try curl - just copy-paste the output of this tool and it'll invoke curl with proper arguments.
you need only python and python's requests module to run the tool. Plus, curl to download .mp4s
I don't deal that much with cache/cookies/storing passwords/etc., so code is compact and clean. Should be quite simple to understand/extend
Usage: python ./extract.py user password 'coursera_class_url' [curl(default)|text|csv|urls]
Example: python ./extract.py [email protected] 'SuperPass!#$%' 'https://www.coursera.org/course/hwswinterface' curl
Example2: python ./extract.py [email protected] 'SuperPass!#$%' 'https://class.coursera.org/digitalmedia-002/lecture/79' text
Call it like
python ./extract.py [email protected] 'SuperPass!#$%' 'https://class.coursera.org/digitalmedia-002/lecture/79' curl
You'll get the following output (showing only first 3 lines):
curl -C - -o 'Video_(MP4)_for_1.1_introduction_(2_28).mp4' 'http://d396qusza40orc.cloudfront.net/digitalmedia/recoded_videos%2FCP%20-%20Lecture%201.2%20Sonic%20Painter%20%20%5Be82173eb%5D%20.mp4'
curl -C - -o 'Video_(MP4)_for_1.2_Processing_(2_35).mp4' 'http://d396qusza40orc.cloudfront.net/digitalmedia/recoded_videos%2FWk1p3%20%281280%20x%20720%29%20%5B3a791a0f%5D%20.mp4'
curl -C - -o 'Video_(MP4)_for_1.3_Running_Apps_on_Android_(3_21).mp4' 'http://d396qusza40orc.cloudfront.net/digitalmedia/recoded_videos%2FCP%20-%20Lecture%201.3_fixed_audio.38eec000f88011e3bdfc196b7e6e218b.mp4'
pass it to your friends, or if you want to download .mp4s yourself - just copy-paste the output to console and curl will download the whole stuff for you.
Don't worry if you had to terminate in the middle - just copy paste again and curl will continue from the position where it stopped.
This is just a way how you want to represent the output. By default it's curl, but you can choose:
curl -C - -o 'Video_(MP4)_for_1.1_introduction_(2_28).mp4' 'http://d396qusza40orc.cloudfront.net/digitalmedia/recoded_videos%2FCP%20-%20Lecture%201.2%20Sonic%20Painter%20%20%5Be82173eb%5D%20.mp4'
