Subject: - Fixed the "403: Forbidden" errors for newly uploaded videos on
 unpopular channels.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When "dashManifestUrl" or "sc=yes" is detected, we now use the fallback extraction method (hypervideo or invidious instances).
