Question

I have an active Safari Books Online subscription and I tried downloading video courses(indicated by: ) there for offline viewing using youtube-dl's bulk download feature. However, the videos downloaded do not have the best quality as shown below:

Those videos which display length is of 1080p, while the videos which are empty under the length column is of 720p(This was checked using VLC media player's Codec Information). However, on Safari Books Online, all the videos are of 1080p. I tried using youtube-dl -f 'bestvideo+bestaudio/bestvideo+bestaudio' --merge-output-format mp4 or youtube-dl -f best, but it did not solve the problem. Is anyone else experiencing this problem or has anyone found a solution to this? Thank you.

P.S. The above course is taken from here, but it is not the only course facing this problem.

After a whole day of experimenting, I found a solution. While specifying bestvideo[height<=1080] did not work, it worked when you specify worst[height>=1080]. I posted this to help those who faced this problem and I will close this issue.

Hi, on unrelevant topic. How were you able to download videos from safari. I get error of unsupported link. Can you kindy share your config/command line?

You can refer to this for more detail: https://www.quora.com/How-can-I-download-videos-from-Safari-Books-online. However, under the config, change the last line to this best[height>=1080] if u wanted 1080p videos. Take note that learning paths are not supported by Youtube-dl
