I'm developing news app which is showing YouTube matching embed video on click news post, I'm not owner any of those videos, but I want to place Admob banner ad to the bottom of the video, I saw this post about possible copyright strike from Google or YouTube, but I need to be sure about that before add ads on location showed in image below.
If there are no ads on that specific Youtube Channel i.e. the videos are not monetized via AdSense
, you can show AdMob's ads afaik.
Do cross-check the policies though, these policies tend to change quite often.
Note: If the YouTube Channel someday starts to monetize its content, your AdMob account will be at risk so head with precaution.
