When I'm using iMac it is ok. Player is sending request to this playlist and there is no problem with connection to the server.
But when I'm using iPhone there is always a problem that iPhone does not provide client certificate (I do NOT REQUIRE IT): OpenSSL: Exit: error in SSLv3 read client certificate A
Anyway. It seems that iphone media player does not associate trusted connections / used client certs with safari so I can't really create safe video tag. Somebody can help me with providing https video playlist on iphone? Is it possible?
