Sure, I hate it too. When I use video tag in my website, if I open it from my chrome on my mobile phone, I see Chrome Cast icons on each videos that I have. How to disable such icons?
It is easy. Just add this css code to your page’s stylesheet:
video::-internal-media-controls-overlay-cast-button {
display: none;
}
After testing this css code on my phone, I no longer see such icons again. Nice! Thanks, internet…
