This is the draft agenda for the media mini-summit in San Jose on March 26th.

Time: 9 AM to 5 PM (approximately)
Room: TBC (Mauro, do you know this?)

Attendees:

Mauro Carvalho Chehab - [email protected] - Samsung
Laurent Pinchart - [email protected] - Ideas on board
Hans Verkuil - [email protected] - Cisco

Mauro, do you have a better overview of who else will attend?

Agenda:

Times are approximate and will likely change.

9:00-9:15   Get everyone installed, laptops hooked up, etc.
9:15-9:30   Introduction
9:30-10:30  Media Controller support for DVB (Mauro):

1) dynamic creation/removal of pipelines
2) change media_entity_pipeline_start to also define the final entity
3) how to setup pipelines that also envolve audio and DRM
4) how to lock the media controller pipeline between enabling a pipeline and starting it, in order to avoid race conditions

See this post for more detailed information:

https://www.mail-archive.com/[email protected]/msg85910.html

10:30-10:45 Break
10:45-12:00 Continue discussion
12:00-13:00 Lunch (Mauro, do you have any idea whether there is a lunch organized,
or if we are on our own?)
13:00-14:40 Continue discussion
14:40-15:00 Break
15:00-16:00 Subdev hotplug in the context of both FPGA dynamic reconfiguration and
project Ara (http://www.projectara.com/) (Laurent).
16:00-17:00 Update on ongoing projects (Hans):
- proposal for Android Camera v3-type requests (aka configuration stores)
- work on colorspace improvements
- vivid & v4l2-compliance improvements
- removing duplicate subdev video ops and use pad ops instead
- others?

Most of the time will be spent on DVB and the MC. Based on past experience this likely will take some time to get a concensus.

Comments are welcome!

Regards,

Hans

There's also the topic of the media device controller registry that we discussed during the FOSDEM, but as far as I know there has been no progress in that area.

Mauro, do you have a better overview of who else will attend?

This time, we'll be using ELC registration site to track. I'll see how we can get this info with LF as well, but, as people can join it dynamically, the best is to get the list with them on Thursday evening, and double-check during the Summit to track last-minute changes.

I am attending as well. Could you please add discussion on Media Tokens. I will send out a 5 patch RFC series. We can discuss to see if it is worth while continuing this work.

I asked the LF how I should register to attend the mini-summit only, they said - no, no need to register, attending just a mini-summit is free. So, expect unregistered visitors like me ;)
