[mythtv-users] is it possible to configure netvision youtube to identify as an ipad ?

[Alex Halovanic]

Sort of, although I'm not totally sure exactly how the iPad app works at
this point...

Youtube supports two types of video formats: Flash and HTML 5 but not all
of their videos have HTML 5 versions.  My understanding of the available
Youtube APIs is that HTML 5 for supported embedded videos only happens if
a) You opt into the HTML5 trial at youtube.com/html5 on your browser or b)
don't have Flash at all.

In addition, MythNetvision needs to be patched to load the iframe API from
youtube, otherwise only Flash video can load.  I have a patch to do that
against this ticket:
http://code.mythtv.org/trac/ticket/11092

If you're willing to try it out and let me know what you see, here's what
you have to do to enable HTML 5 youtube videos:
1) Patch the youtube.html file from ticket 11092.
2) Visit youtube.com/html5 in Mythbrowser. Confirm it says that HTML 5 is
supported for all formats and click the link to join the trial.  You need
to do this every time you start mythfrontend since it doesn't seem to save
the cookie permanently.
3) Search for 'big buck bunny' in Mythnetvision and start playing.  If you
right click on it, you should see a different menu from the Flash one.

Caveats:
-There are some focus issues, although I think these exist with the normal
Flash player as well in some circumstances.  If you click on a video with
your mouse, the remote control keybindings won't work anymore.  I'd
recommend having a keyboard/mouse connected and disabling the 'hide mouse
cursor' setting in Myth's appearance menu for now.
-The iframe player has a tiny red progress bar at the bottom to show the
playback status that you can't seem to get rid of.  Might annoy some people.
-This tends to crash out mythfrontend, especially on trying to exit the
video.  I think this is reduced most by *pausing* the video before trying
to exit it.  Depending on how much Flash crashes for you, this may still be
an improvement.
-Video still has some tearing and is not as hardware accelerated as it
could be.  This is because of how the QT library is drawing it using Cairo,
I believe.  I hadn't looked too closely at what it would take to enable
something like VDPAU here.  For my case, performance still seems better
than unaccelerated Flash.
-You either have to remove the Flash plugin permanently (and lose all
Flash-only videos) or repeatedly opt into the HTML 5 trial for every time
you restart mythfrontend.
