[vlc-devel] OpenHMD branch?

[Alexandre Janniaux]

Hi,

Thank you for your interest in this, don't hesitate to give some
feedback about what you expect.

The tag used for the demo at CES2019 is there[1]:

[1]: https://github.com/alexandre-janniaux/vlc/tree/demo-ces2019-vlc-vr

It's taylored for demo so it's using the lua interface and it keeps the
HMD at the same state between videos, and offers control over http to
switch the item in the playlist. It doesn't offer direct display on the
headset though (which needs a vulkan renderer) so you need to configure
the screen as soon as the headset is started. I might be able to find 
the
startup script used for the demo, I'll post them here if I recover this.
I would advise to start the demo on an existing playlist file so you
don't have to create the whole playlist each time or if an issue arise.

I'm currently in the process of merging this so I have more recent and
cleaner work on this, but it's destructured into multiple branch. I can
try to provide you a more up-to-date partial version using these 
branches
if you want. I hope to have sent here at least the full HMD+360 support
before the end of next week, if you're ready to wait until then 
otherwise.

There are additional resources that you would need if you want to try 
the
VR Theater demo, I'll check how we can distribute them.


Greats,
