This is the final agenda for the media mini-summit in San Jose on March 26th.
Time: 9 AM to 5:30 PM (approximately) Room: San Carlos, 2nd floor
Attendees:
We'll get this list later from the Linux Foundation based on who signed on.
Agenda:
Times are approximate and will likely change, although the intention is to not change too much :-)
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 Carvalho Chehab): 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:

There is another thread that it is also relevant for the discussions. In order to help with the discussions, I prepared a set of slides that explains how the DVB pipelines are and what are the issues with MC.
They're at: http://linuxtv.org/downloads/presentations/media_summit_2015_US/dtv_media_co...
I added there the links for the related messages that were sent to the mailing list. Please notice that the example at slide 8 is fictional, as getting those hardware diagrams would generally require to sign an NDA. So, the example were created from a slide that I found at the Internet, under: http://www.eetasia.com/ARTICLES/2005AUG/4/2005AUG22_EMS_NP.gif
where I merged the missing entities demod and demux, and guessed that the output could be sent through GPU and ALSA pipelines, and that cross-bars would allow different pipeline arrangements.
So, while it is a fictional diagram, it is actually pretty close to what would happen on a real hardware for a TV set or a Set Top Box.

10:30-10:45 Break 10:45-12:00 Continue discussion 12:00-13:00 Lunch 13:00-14:30 Continue discussion 14:30-15:00 Media Tokens (Shuah Kahn) 15:00-15:30 Break 15:30-16:30 Subdev hotplug in the context of both FPGA dynamic reconfiguration and project Ara (http://www.projectara.com/) (Laurent Pinchart). 16:30-17:30 Update on ongoing projects (Hans Verkuil): - work on colorspace improvements - removing duplicate subdev video ops and use pad ops instead - vivid & v4l2-compliance improvements - proposal for Android Camera v3-type requests (aka configuration stores)
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 consensus.
