HTML5-Code:
<video id="video1" class="video" poster="img/poster.png">
<source src="video1.webm" type="video/webm" >
<source src=video1.mp4" type="video/mp4" >
</video>
works on iPad without problems using webserver (Apache, PHP7).
If I use the same configuration with .htaccess the video will not be loaded and played. This is a problem with iPad only. Desktop (Win7, Win8, Win10, OS-X) or Android Tables are loading the mp4 without any problems.
htaccess-Code:
AuthUserFile serverpath/pasbin/.htpasswd
AuthName "LOGIN REQUEST"
AuthType Basic
require valid-user
order deny,allow
deny from all
