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, 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 [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
Opus in MP4
We should sit down and design this mapping.
Binary Album Art extensions for Ogg
We've had a proposal to include binary (not base64-encoded) album art for Ogg in the context of Ogg Opus: <http://www.ietf.org/mail-archive/web/codec/current/msg03061.html>. This session would determine if there is interest from players in supporting such an extension and working on the design.
Testing
Seems like everybody is doing the same very flaky or very manual thing when testing video processing and player software. Can we do better?
- like a fate suite of tests for players? Maybe with an scriptable mouse click? Assuming your player can be launched in a set coordinates.
Broadcasting things
An attempt to justify what broadcasters are doing.
arm64 / AArch64
CPU specific optimizions for iOS devices, upcoming android devices, arm based servers
The bare basics of special relativity
An brief introduction to the basic concepts and consequences of special relativity.
Chocolate
Daala
Open to anyone curious about Daala, and if you want to win a T-shirt we'll help you write your first patches! See also https://wiki.xiph.org/Daala_Quickstart
Wayland
Principles, challenges, progress and way forward with multimedia on Wayland
Practical information
Location
The meeting is held in Dublin, Ireland.
Feel free to use Flameeyes as local point of contact before, during and after the event.
Emergency situation
In case of emergency, call the European emergency number 112. The UK number 999 also works.
Payment
Most venues will accept credit and debit cards as long as they are Chip & PIN; American swipe cards can be slightly more tricky but not exceedingly. American Express is barely accepted.
Accomodation
For sponsored participants, there are two different hotels this year. Check your mail to know which one applies to you.
| Sandymount Hotel | Mespil Hotel |
|---|---|
| Herbert Rd, Lansdowne Rd Dublin 4 |
60 Mespil Rd Dublin 4 |
| Directions | Directions |
Transportation
Both hotels can be reached from the airport using the Aircoach bus service at 8€/one way, 14€/return. For the full list of bus services, bus/coach check the airport site.
Regular bus lines like 16 every 20min for only 2.20 euro
Taxi from the airport is estimated at 30-40€ one way. Tipping (10-20%) is optional but appreciated. If the driver offers to take the tunnel, note that it involves a 3€ surcharge.
We recommend against renting a car as parking in the city can be challenging (and also to many people, driving on the left side of the road).
NOTE: VideoLAN does not refund taxi expenses nor car rentals.
Main venue
Google Docks, in Barrow Street.
Connectivity
Power supply
The electrical sockets are "British" IEC type G with three prongs a.k.a. BS 1363.
The electrical system is 220V / 50Hz. If you come from the Americas, please make sure your devices are compatible beforehand.
Hotel bathrooms are often an exception, providing 110/220V split sockets, accepting US and Europlug connectors (not grounded). They are marked as "shavers only".
Internet
At the venue, the GoogleGuest open WiFi is available at all times.
Most hotels and coffee shops will have available WiFi, but some might require registration.
The airport has a free WiFi network with captive portals.
SIM cards can be freely bought with nothing more than an ID and a card/money.
Weather
Dublin forecast for September 19th is 17°C high and 13°C low with 30% risk of rain and a gentle breeze.
