[ANN] Media Summit May 13th: Draft Agenda (v2)

[ANN] Media Summit May 13th: Draft Agenda (v2)

[Hans Verkuil]

Hi all,

Here is my v2 of the draft agenda for the media summit. The only changes
are dropping Sebastian's email and fixing Devarsh' email.

As always, this draft agenda is subject to change and all times are guesstimates!

Please note that I am transitioning from my old hverkuil@xs4all.nl email to
my new hans@jjverkuil.nl email. If you have problems replying to that new email,
please let me know and just send it to the old email (that won't go away).

The Media Summit will be held Tuesday May 13th to coincide with
the Embedded Recipes Conference in Nice, France:

https://embedded-recipes.org/2025/

Note that there are also some workshops held after this conference:

https://embedded-recipes.org/2025/workshops/

And a gStreamer hackfest:

https://discourse.gstreamer.org/t/gstreamer-spring-hackfest-2025-on-16-18-may-2025-in-nice-france/4366

The Media Summit will be held at Hotel Campanile:

https://nice-aeroport.campanile.com/en-us/

It is close to the Airport and to the Embedded Recipes venue.

The meeting room can hold up to 30 people and has video conferencing support; it is
sponsored by Collabora and Cisco Systems Norway.

We currently have the following confirmed in-person attendees:

Sakari Ailus <sakari.ailus@linux.intel.com> (Intel)
Mauro Carvalho Chehab <mchehab+huawei@kernel.org> (Media Maintainer, Huawei)
Nicolas Dufresne <nicolas.dufresne@collabora.com> (Collabora)
Hans de Goede <hdegoede@redhat.com> (RedHat)
Paul Kocialkowski <paulk@sys-base.io> (sys-base)
Jai Luthra <jai.luthra@ideasonboard.com> (Ideas on Board)
Laurent Pinchart <laurent.pinchart@ideasonboard.com> (Ideas on Board)
Ricardo Ribalda <ribalda@chromium.org> (Google)
Maxime Ripard <mripard@redhat.com> (RedHat)
Devarsh Thakkar <devarsht@ti.com> (Texas Instruments)
Hans Verkuil <hans@jjverkuil.nl> (Media Maintainer, Cisco Systems Norway)
Arthur Vinchon <arthur.vinchon@allegrodvt.com> (Allegro DVT)

As you can see, there is enough room for more people, so don't hesitate to
register by sending an email to me. The deadline is May 2nd.

And the following remote participants:

Marco Felsch <m.felsch@pengutronix.de> (Pengutronix)
Martin Hecht <mhecht73@googlemail.com> (Avnet Silica)
Hu, Jerry W <jerry.w.hu@intel.com> (Intel)
jackson.lee <jackson.lee@chipsnmedia.com> (Chips 'n Media)
Mirela Rabulea <mirela.rabulea@nxp.com> (NXP)
Michael Tretter <m.tretter@pengutronix.de> (Pengutronix)

Note: information on how to connect remotely will come later.

If any information above is incorrect, or if I missed someone, then please let me know asap.

Draft Agenda:

9:00-9:30: Get settled :-)

9:30-9:40: Hans Verkuil: Quick introduction

9:40-10:30: Jai Luthra: Per-stream V4L2 controls

10:30-11:15: Paul Kocialkowski: Stateless video encoding uAPI

11:15-11:30: break

11:30-12:15: Ricardo Ribalda: Openness Framework for ISPs

12:15-13:30: lunch TBD

13:30-14:00: Laurent Pinchart: Review of the status of staging drivers

14:00-15:00: Hans Verkuil: Status of Media CI/Multi-committers

15:00-17:00: TDB

Please reply with corrections, questions, etc. to this email. I'll update the agenda
over time. Again, these times are very preliminary.

Also, as you can see we are light on topics, so don't hesitate to add more.

Part of the reason for this is that we switched to co-locating from the ELCE to the
Embedded Recipes conference, so it is only 8 months since the previous Media Summit.

Regards,

	Hans

As discussed here:

https://lore.kernel.org/linux-media/6cf8d6db-c24e-461b-bd7d-a3dad25e4945@redhat.com/

there are a bunch of V4L2 (subdev) API things which need
to be specified better (without leaving room for interpretation)
surrounding sensors. One of these is how to calculate the pixelrate
(and thus the FPS) for sensors when e.g. binning is used.

For non binning the pixelrate in pixels/second is:

pixelrate = (format.width + hblank) * (format.height + vblank) * fps

But what about binning, should the sensor driver then report the
skipped pixels as extra vblank (AFAICT that is what it looks like
on the CSI-2 bus) or should userspace know binning is happening and do:

(format.width * hscale + hblank) * (format.height *vscale + vblank)

and in that case how can userspace know hscale / vscale since atm
it cannot explicitly set those, but this is determined by the sensor
drivers.

There are a number of questions like these surrounding the V4L2 subdev
API for sensors, which IMHO would be good to discuss.

Hans

Thank you. I added this topic to the draft agenda. Do you have a guesstimatefor the time you need for this?

We could spend the whole day discussing raw sensors :-) If time permits,
extending this topic to discuss how to standardize exposing binning and
skipping to userspace.

If we discuss this topic in the Media summit, then it be discussed in the
context of the metadata patch series
<URL:https://git.linuxtv.org/sailus/media_tree.git/log/?h=metadata> and
especially the Common raw sensor model rather than the current state of
affair. We know what's in upstream right now is insufficient and what is
documented there isn't fully supported in current drivers.

Hans, as Laurent says I think we can easily fill an hour with this,
so sat 45 min or 1 hour ?

Sakari, I agree we should probably base the dicussions on the new common
raw sensor model. I will make sure to have read all the current code / docs
on that before the summit. Can you maybe prepare some discussion points
for the summit based on this ?

Hans

I'd like to propose identifying camera modules as a topic.

The camera module isn't a functional component in the system and so has
(mostly) been omitted in system firmware as well as UAPI. Being able to
identify it, however, is becoming more and more important as the user space
becomes less and less system specific, largely thanks to libcamera. This
isn't just about passing information to the userspace as identifying the
modules themselves is a problem on its own.

I intend to post an RFC set regarding this to LMML at least a week before
the summit.

I'd guess from 30 to 45 minutes, but it heavily depends on how much there
will be discussion.

Ups sorry, seems like I'm late :)

I procrastinated to these days as I would have liked to be able to
propose a well structured topic about multi-context support which was
presented 8 months ago. Since then I paused working on it but I should
be able to reserve time in the following months.

Unfortunately I wasn't able to dedicate much time to that, however in
the weeks before the media summit I would like to explore a bit how to
unify the multi-context support with the m2m context handling, with
the aim to use a single mechanism to support both.

If you have a tiny 15/20 minutes slot I would be glad to present a
plan to you, Nicolas and other more well versed in codec support than
me.

Thanks and sorry for being late.

No problem! I've added a slot for this topic. I think I can safely assume
you'll be there in person?

In any case, both the agenda and the participants list are now nicely filling up :-)
