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)
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

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.

I uploaded RFC 5 patch series to my kernel.org git media branch
for this discussion:
https://git.kernel.org/cgit/linux/kernel/git/shuah/linux.git
clone:
git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux.git

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_controller_discussion_v1.pdf
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.

Mauro
