Caused by using the tokenized link to JSON.
Description
I've been trying to download some files of off my institute's website. They use jwplayer with the
{media_id}-{player_id}.jsformat. The .js file contains the exact URL (token included) to access the required JSON metadata but youtube-dl doesn't work even if I have provided the actual tokenized version of the JSON link.A solution I've come up with works on all video preview page that is obtained by using any link of the format
https://cdn.jwplayer.com/players/{media_id}-{player_id}.htmlA js parser(noob's implimentation below) that extracts the
var jwConfig = {}from the script_tag and subsequently extracts the correct media_uri/playlist_uri would do the trick.The .js data(request.content) should be treated as a str/bytes object and split using the (";") delimiter. The element [-5] (please verify) should be the appropriate variable (jwConfig). Removing the
var jwConfig =(incl. spaces) then usingjson.loads()to get a dictionary. This dictionary has a playlist key which contains the JSON metadata. (might also have to replace the // with https://)Probable solution for the preview page of most media files (jwplayer-hosted/cloud-hosted)
When visiting the playlist url returned after this, we get a JSON document similar to the ones we get when using a untokenized media.
