Philippe: talking about the FOSDEM presentation, if some time is left we could mention the backlog tasks.
FOSDEM presentation
- The presentation will be recorded tonight
- Piotr already has a recorded Video
- Meeting done on Tuesday regarding this topic
- Brief slide overview done
- Differences between Android on phone vs Android in automotive
- Mention some of the requirements in different automotive branches (mentioning connected cars, ADAS, Powertrain, etc.)
- Aim is: can Android Automotive cater to all these requirements?
- Introduce design options (system controlled inside or outside of Android)
- Common problems in both design options, our starting points
- Extracting and injecting RAW strems (slides to follow with the POC and Demo) - This would be done by Piotr
- Audio network options (slides about previous problems in network: time, delay, etc.) and their solutions (standards solving the problems)
- suggesting Automotive Audio Bus (A2B)
- Further investigations (listing other topics - in our backlog) and what could be done as part of this aim
- Team currently working on this and more information to follow
- Live Q&A will follow with Matrix chat system, specifically here is the link for FOSDEM matrix
- In addition there will be a voice or real time interaction with the moderators etc

Tasks in the backlog topic
- New Sprint AASIG Sprint 6 created
- let's start by defining a road map for this year
- We soon will have some milestones from the board meeting
- Discussion about what to do first. Suggestions:
- Road map for the project with what is needed from a technical point of view. Create priorities. Fix the sprint according to resources.
- Check the resources and decide what current tasks are being worked on
- Piotr shared his screen to check the current backlog and epics.
- let's go through the issues or tasks that are in-progress and check how we can close them or postpone them etc.
- AASIG-70: This will be closed soon (Piotr)
- AASIG-86: Are there any artefacts that we can present, do we go futher on this task → moved out of the sprint to the backlog
- AASIG-92: This is more interesting than AASIG-86 but more complex. Maybe we can be break it down to studies and overtime consider how to implement it. The first step seems doable though. The DOD (definition of done) is to define the API and protocol. maybe let's break it into sub-task to add DOD in the sub-task to show a diagram for example or a design, etc. → moved to the backlog.
First let's define the sub-task (in the next session AUDIO_HAL CW03)
- Proposal for the structure of the source code (Piotr Krawczyk: Could you please share the ppt when it's ready)
- we can have several repositories with manifest, with aasig_dev_configuration, and several repos depending on the services (vss, external audio mixing, vehicle plugin, etc.)
- downloading and building would be easily done.
- then we are modular and we can define the components that we would like to add to the build easily and we would share common parts.
- Together with Stephen: prepare action steps to prepare and implement this structure
- Gunnar will create the repos and support
- We also need to combine this with RENESAS build steps
- @All: Please have a look at the backlog to be prepared for the next meeting.

- Slides from Wassim about the two models inside and outside of AA
- discussion of the cases/features that we are trying to solve
- checking the Audio Manager to decide whether or not it needs an update
Minutes
- 2 strategies or options:
- android provides sources and sinks
- Android controls the complete systems
- We will not discuss the need to have such options
- Basically some functions cannot be integrated to AA
- Audio sources coming from android or from external (android not aware of them)
- Each strategy has limitations and can be criticized
- Idea is to get each model and apply to it questions/cases
- Questions like safety sources, raw streams, etc.
