=== Daala hackathon ===
Open to anyone curious about Daala or video coding in general, we can help you write your first patch or teach you things!

To get started you can clone the Daala repository:

<code>
git clone https://github.com/xiph/daala.git
</code>

* How to build and run Daala: https://wiki.xiph.org/Daala_Quickstart
* Demonstrations and explanations of some of the techniques used in Daala: https://people.xiph.org/~xiphmont/demo/
** Note that some of the older demos do not match what is in Daala anymore.
** For more details see https://wiki.xiph.org/Daala#Documents and https://wiki.xiph.org/Daala#Presentations
* Easy bugs to fix: https://github.com/xiph/daala/labels/easy

=== Dinner ===
Around 19:00 at ''Au Metro''.

19 Rue de Malte, 75011 Paris
Metro ''Filles du Calvaire'' or ''Oberkampf''

This dinner is '''not''' sponsored by VideoLAN.

= Practical information =

== Emergency situation ==
In case of emergency, call the European emergency number '''112'''.

== Location / main venue ==
The venue is in Paris (France), 9th district, near St Lazare:

Criteo<br/>
32 rue Blanche<br/>
75009 Paris, France

[https://www.google.fr/maps/place/Criteo/@48.878914,2.3315591,17z/data=!4m6!1m3!3m2!1s0x47e66e04d509ec8f:0xbf35e94464e752f7!2sCriteo!3m1!1s0x47e66e04d509ec8f:0xbf35e94464e752f7 Google Maps]

== Accomodation / Hotel ==
For sponsored participants, the hotel is: 

Timhotel Berthier Paris 17<br/>
4 Boulevard Berthier<br/>
75017 Paris, France

http://www.timhotel-berthier-paris-17.com/<br/>
[https://www.google.fi/maps/place/Timhotel+Berthier+Paris+17/@48.894398,2.312611,17z/data=!3m1!4b1!4m2!3m1!1s0x47e66f9878ba126d:0x24a180f7131eebe5 Google Maps]

== Payment ==
The local currency is the Euro. Merchants are forbidden from accepting other currencies (except exchange).

Most venues will accept EMV credit and debit cards (i.e. Chip & PIN), at least VISA and MasterCard. Swipe-only cards can be more tricky (it has been illegal for banks to issue them for years in France, so only foreign visitors use them). American Express is widely but not universally accepted. Diners/Discovery, UnionPay, JCB, etc. are mostly only accepted in shops catering to tourists.

Best change rates are close to the Hotel, Metro Bourse, Vivienne Street.

== Transportation ==

* Public transport: [http://www.ratp.fr/itineraires/en/ratp/recherche-avancee RATP]
* Attendees arrival & departure list: [[VDD15/Attendees]]

'''NOTE''': VideoLAN does not refund taxi expenses nor car rentals.

=== Paris-CDG / Roissy airport ===

'''Important note:''' there are works on the RER B line at night until Friday, included. The RER B service is interrupted between the airport and the Aulnay-sous-Bois station at 11pm. There is a replacement bus available but this incurs a much higher trip time. More information: http://www.transilien.com/contents/fr/Docs---PDF/Travaux/20150720-B-Roissy-2007au3010bis.pdf

=== Internet ===
Hopefully, there will be Wi-Fi.
