Apple does not allow you to download the WWDC videos locally, hence I found this way to download the videos for offline use. This might be useful in countries where the internet speed is slow.
Following is the 5 step process to download any WWDC 2014 video to your mac.
Step1:- Open the link “https://developer.apple.com/videos/wwdc/2014/” in your web browser. and login with your developer account if prompted
Step2:- Save the html page as video.html in a folder on your mac.
by going to File Menu -> Save As command in your web browser
Step3:- Run the following commands in terminal
1) Navigate to where you saved your video.html file
2) Get a list of SD video links
For SD vidoes (low quality, small file size)
grep ".mov" video.html| grep "_sd_" |cut -d'"' -f4
3) OR Get a list of HD video links
For HD vidoes (high quality, huge file size)
grep ".mov" video.html| grep "_sd_" |cut -d'"' -f2
Step4:- Copy the link (one link at a time) of the video you want to download from the list presented by the above commands in the terminal window.
Then run the following command on your terminal window
curl “paste copied link here” > name_your_video.download
RA$ curl http://devstreaming.apple.com/videos/wwdc/2014/143hceerhhc283299/212/102_sd_platforms_state_of_the_union.mov?dl=1 > platforms_state_of_the_union.download
This will start the download of the .mov file
Step5:- Once the download is complete rename the file
mv file_name.download file_name.mov
or by navigating to the folder using the finder.
Voila!! Now you have the WWDC video for offline use. Enjoy learning.
