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:

https://www.mail-archive.com/linux-media@vger.kernel.org/msg85910.html

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)

One item is missing:

17:30 - Group photo

:)

It would also be nice to use 15 mins at the end to double check if the model of subscribing via LF was a good idea, or if something needs to be improved for the next Summits.

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.

Regards,

Hans

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.
