How can I found the YouTube Channel name of this video? The Video is unavailable (YouTube shows message that video is unavailable as the account is terminated). Also TheWayBackMachine don't have Snapshot (It does have one snapshot which is also unavailable).
In general: If you search for the Video ID (the part after
youtube.com/watch?v= and before any
&something=somethingelse), you often can find YouTube downloaders and pseudo-mirrors which may or may not contain the meta data you're looking for.
In this specific case, while I couldn't find the channel name, I did find the original on the CCC website: https://media.ccc.de/v/30C3_-5552-en-_saal_g_-201312291130-_india_s_surveillance_state_-_maria_xynou
