Description

youtube-dlc does not recognize subtitles on roosterteeth.com.
Links that were tested:

• https://roosterteeth.com/watch/rwby-season-1-episode-1
• https://roosterteeth.com/watch/rwby-season-1-episode-2
• https://roosterteeth.com/watch/rwby-season-1-episode-3
• https://roosterteeth.com/watch/rwby-season-1-episode-4
• https://roosterteeth.com/watch/gary-and-his-demons-season-1-still-the-one

I am able to load all the subtitles using the built-in player, so this is a youtube-dlc issue. The exact same issue is present in pukkandan's fork, and an issue has been made there as well.
A pull request is made on youtube-dl's repo here, but has not been merged for several months.

This has been fixed in youtube-dlp. I recommend merging this pull request as a possible fix. This issue still remains in this fork, so this will remain open.

This repo is no longer maintained anyway. The official youtube-dlc repo is moved to https://github.com/blackjack4494/yt-dlc after the DMCA takedown.
