worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable

Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or

pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

HomeAssistant VLC HTTP component
================================
This component let's you add a remote VLC as a media_player to your
HomeAssistant instance.
Preconditions
-------------
- A computer which is accessible via network by HomeAssistant running VLC
- The Web interface in VLC is enabled, [see this how-to](https://www.howtogeek.com/117261/how-to-activate-vlcs-web-interface-control-vlc-from-a-browser-use-any-smartphone-as-a-remote/)
- This component is installed in HomeAssistant (*config*/custom\_components/vlc_http)
- This component is enabled in the configuration.yaml like this:
```yaml
media_player:
- platform: vlc_http
host: 192.168.2.20
port: 8080
password: !secret vlc_http_password
```
After doing that you need to restart your HomeAssistant.
Notes
-----
It only works with HTTP because the VNC Web interface is only available via
HTTP and not HTTPS.
You can autostart VNC on your computer and it will play for example text to
speach messages from HomeAssistant on it while you're on the computer, without
the need of an additional speaker connected to HomeAssistant.
This component is basically a copy of [vlc_telnet](https://github.com/home-assistant/home-assistant/tree/dev/homeassistant/components/vlc_telnet)
but it replaces the Telnet backend with a HTTP backend.
I hope I will be able to get it into HomeAssistant one day, perhaps by
extending the vlc_telnet component instead of having a copy of it.
License
-------
This code is under the same license as HomeAssistant: Apache License 2.0
