Yes, I get this too, but there's no noticeable difference between when |
48 |
the button says "... default ..." and when it says "... HTML5 ...". |

Of the six boxes there, I have ticks (?check marks?) on |
76 |
o - HTMLVideoElement |
77 |
o - WebM VP8 |
78 |
I have exclamation marks on all the others, namely |
79 |
o - H.264 |
80 |
o - Media Source Extensions |
81 |
o - MSE & H.264 |
82 |
o - MSE & WebM VP9 |
83 |
. It's frustrating that "HTML5" isn't mentioned in that list of six. |

I'll take your tip and try rebuilding with gstreamer enabled. Thanks! |
