This is the situation:
<video controls><source src="10053.mp4" type="video/mp4"></video>
Not working, won't load video on Samsung browser (Smart TV Q80T model of 2020)
BUT, if you rename the file to .sd.mp4 it works:
<video controls><source src="10053.sd.mp4" type="video/mp4"></video>
It works!
Anyone knows how to fix this without rename all .mp4 files? Any knows how to add a an entry to .htaccess in order to set on url .../[0-9+].hd.mp4 and look into the system .../[0-9+].mp4 ?
The issue is caused by a wrong .htaccess policy trying to block hotlink or play in a wrong referer.
RewriteCond %{HTTP_REFERER} !^https://URL.*$ [NC]
RewriteRule ^(.*)/([0-9]+)\.mp4$ https://URL/ [R,NC]
</FilesMatch>
Removing or commenting RewriteRule
fixes it.
