Author: stabbedbybrick

Robustness:
Widevine:
L3: 2160p, AAC2.0
ClearKey:
AES-128: 1080p, AAC2.0

Tips:
- Input can be either complete title URL or just the path:
SHOW: /show/richard-hammonds-workshop
EPISODE: /video/richard-hammonds-workshop/new-beginnings
SPORT: /video/sport/tnt-sports-1/uefa-champions-league
- Use the --lang LANG_RANGE option to request non-english tracks
- use -v H.265 to request H.265 UHD tracks (if available)
\b
Notes:
- Using '-v H.265' will request DASH manifest even if no H.265 tracks are available.
This can be useful if HLS is not available for some reason.
