=== 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 
32 rue Blanche 
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 
4 Boulevard Berthier 
75017 Paris, France

http://www.timhotel-berthier-paris-17.com/ 
[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

[[Image:Paris_Metro_box.jpg|thumb|175px|Ticket vending machines]]

* Upon landing, follow the signs for local trains. There is one station for T1/T3 and one for T2 (A-G).
* At the station, look for '''red/green''' ticket vending machines.
** Do not use the yellow/grey machines (at terminal 2), those are for long distance trains only.
* Buy a ticket for zones 1-5 (to Paris). The cost is 10€ one way. Credit cards are accepted.
** If you only have cash, you have to queue at the staffed ticketing booth ("''Billeterie''" in French)
* Take the regional express(RER) line B (blue). You can use any train toward Paris.
* Alight at ''Gare du Nord''.
* See below from Gare du Nord.

* 2€ Alternative From/To ''Palais Royal /Louvre'': http://www.easybus.com/fr/paris-cdg (online booking), takes 50min

=== Orly (ORY) airport ===

* At the station, buy the ticket from the vending machines, before boarding.
* Buy a ticket for Paris. The cost is 12€ one way. Credit cards are accepted.

=== Beauvais (BVA) airport ===
We feel sorry for you. Take the bus.

=== Gare du Nord (North railway station) ===

If you arrive at Gare du Nord or Gare de l'Est, you need to buy a zone 1 / Paris ticket. It is valid on the subway, the tramway, busses and, '''within the Paris city limits''', on the regional express trains (RER).

==== To the conference venue ====
* Transfer to regional express train (RER) line E (magenta) toward ''Haussmann St Lazare''.

The hotel is just around the corner.

=== Gare de l'Est (East railway station) ===
Routes are essentially the same as from Gare du Nord. The Magenta express train station is located between Gare du Nord and Gare de l'Est. See above.

=== Gare de Lyon (South/East railway station) ===

Feel free to ask for advice on the mailing list if your station is missing.

== Connectivity ==

=== Power supply ===

The AC power sockets are "French" '''IEC type E'''. Connectors from "German" '''IEC type F''' countries should fit safely, as they are usually bi-standards. There should have a hole for the French-style ground pin.

The electrical system is '''220V / 50Hz'''. If you come from outside Europe, please make sure your devices are compatible beforehand.

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

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 
32 rue Blanche 
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 
4 Boulevard Berthier 
75017 Paris, France

http://www.timhotel-berthier-paris-17.com/ 
[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

== Proposed VDD sessions ==

=== Saturday ===
==== VLC 2.2 and 3.0 ====
What's left to be done for 2.2? What are our goals for 3.0? What's the time frame for the next major release? How can we avoid to repeat the 2.2 delay?

==== VLC Mobile Remotes ====
There is a major feature missing in VLC's mobile apps, which is currently provided through third party apps. Control VLC remotely running on a desktop. What needs to be done both on client and server-side to provide an advanced and seamless integration between the platforms?

==== VLC Subpicture Framework improvements for hwaccel rendering ====
As of today for picture type subpictures (DVB Subtitles, VBI pages, ...) a software scale step is forced into the pipeline. To make better use of hardware being able to render scaled overlays this shall be omitted. But it seems some significant changes in the VLC core are required to support this in a common way, which some brainstorming on would be required.

==== Android ====

==== iOS ====

==== WinRT ====

==== libav/FFmpeg discussion ====
Better understanding leads to better cooperation.

=== Sunday ===

==== Libav 12 and 13 ====
Roadmap, [http://wiki.libav.org/Blueprint Blueprints] and so on.

==== Libav whining ====
You have complaints: do voice them! (we will listen and will address them)

==== Libav infrastructure discussion ====
Bugzilla customizations, gitlab, gogs, plaid, and other tools to make our life easier by making some admin life miserable.

==== Road towards HWAccel 2 ====
During this year we moved two steps towards version [[https://wiki.libav.org/Blueprint/HWAccel2 2]]:

* 1.2 -> default context allocators
* 1.3 -> bitstream-oriented hwaccel support

During this session we will discuss about how to provide an
uniform structure to avoid even more boilerplate code and still
allow full control to the people needing it.

==== ChromeCast ====
How do we achieve VLC using Chromecast?

==== Media Library ====
Current state and conception of needed functionality for a cross-platform library to collect meta data, thumbnails and so on for use within media handling applications based on libvlc. Written in C++.

==== EBU-TT-D ====
integration in VLC and/or ffmpeg ?

==== x264 meeting ====
