We're now closed for new registrations: we're 26 in-person attendees and 11 remote attendees. Information on how to call in as remote participant will be given in a separate email next week. This year's Media Summit will be held on Tuesday May 26th the day before the Embedded Recipes Conference in Nice, France: https://embedded-recipes.org/2026/ The Media Summit will be held at Hotel Campanile and in the same meeting room as last year (Nikaia): 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 I will provide video conferencing support, just like last year. The location and the meeting room was quite nice last year, so I saw no need to change it. The meeting room is sponsored by Cisco and Collabora, and the lunch is sponsored by Ideas on Board! Many thanks to our sponsors, it's very much appreciated. Regards, Hans PS: Be aware that May 24 and 25 are public holidays in France. So many shops may be closed those days.

Perez de Azpillaga Dave Stevenson Tomi Valkeinen Arthur Vinchon Agenda: 8:45-9:20: Arrive, settle in 9:20-9:30: Short intro (Hans Verkuil) 9:30-9:45: Status of ISP support in V4L2 Presenter: Laurent Pinchart Description: Summary of ISP-related development in V4L2 since the last Linux Media Summit. This includes a brief overview of technical developments, and a summary of the efforts to engage with vendors. 9:45-10:45: V4L2 Stateless Video Encoding uAPI Progress Update Presenter: Paul Kocialkowski Description: An update on the ongonig work to support stateless codecs in V4L2. Some of the remaining open topics will be presented and discussed. 10:45-11:00: break 11:00-11:30: Vulkan Video Codecs Presenter: Nicolas Dufresne Description: Vulkan video codecs: what are the viable options for Linux Media and what is in preparation outside of our subsystem. The second aspect is informative as these discussions don't seem to lean toward our subsystem as the foundation. But I think it's rather useful for everyone to understand why and what is included. 11:30-12:00: Protected Video playback on i.MX8MQ Presenter: Rouven Czerwinski Description: Introduction to protected video playback on i.MX8MQ and missing bits for linux-media & protected heap interoperability. 12:00-13:30: Lunch 13:30-14:00: HDCP support for HDMI receivers Presenter: Hans Verkuil Description: I have been working on adding HDCP support for HDMI receivers. Specifically the HDCP negotiation between sources and sinks. 14:00-14:15: How to progress on Module identification Presenter: Stefan Klug Description: In many real world use cases it is necessary to identify the exact module/lens combination on top of the currently used sensor to be able to provide corresponding tuning data. I'd like to recap on the existing ideas and add a few more thoughts on how we could solve that. 14:15-15:00: Common raw sensor model, streams, metadata and metadata series status Presenter: Sakari Ailus Description: The Common Raw Sensor Model defines a new UAPI for camera sensors in Linux. It provides a more useful UAPI for configuring camera sensors than the existing practice is. The metadata series includes the Common Raw Sensor Model and a number of other improvements, such as generic raw formats, metadata support and finally enabling the streams uAPI. 15:00-15:30: AI patches Presenter: Sakari Ailus Description: What is our policy w.r.t. AI generated patches? 15:30-15:45: Break 15:45-16:00: A case for a media-job scheduler Presenter: Jacopo Mondi Description: Dan has proposed last year a framework for scheduling operations across multiple drivers that compose a capture pipeline: https://www.spinics.net/lists/linux-media/msg279502.html To better clarify why this is useful, I would like to discuss and describe a practical use case based around the Mali-C55 ISP as integrated in the Renesas RZ/V2H(P) SoC. 16:00-16:30: The Butterfly Effect or How Support for Complex Hardware may affect the uAPI Presenter: Michael Riesch Description: Video capture and camera hardware in recent SoCs is exceedingly complex and the assumption that there is one central V4L2 driver that registers the media device does not necessarily hold anymore. IMHO we need a central media device to rule them all and adaptations to the v4l2_{async,device}_register_subdev code. - Dynamic (de)registration of media entities is desired - This requires considerations about the uAPI - There is significant overlap with the notion of fault-tolerant V4L2 - There is also a ton of cleanup work, but the resulting patches must not break anything existing - So we need to talk about possible migration strategies in order to achieve reasonable progress without interfering too much with existing and working parts 16:30-17:00 Overview of Media CI: where do pipelines run? Presenter: Ricardo Ribalda Description: How are jobs in pipelines assigned? How does the infrastructure for Media CI work? Are there things that can be tweaked to make it more reliable? 17:00-17:45: Discussion of the media subsystem development process Presenter: Hans Verkuil Description: Review of the multi-committer model: current status and next steps. Are there any bottlenecks, any ideas for improvements, w.r.t. the development process?
