Discussion about
Jira | ||||||||
---|---|---|---|---|---|---|---|---|

- Would there be any limitation? maybe apart from ASIL limitation
- References were added to the task detail
- Configuration options range from plugins or configutation language (xml configuration file for examle)
- XML configuration file disadvantages:
- one person deciding what can be configured (limitation by the developer)
- static or compile time let's say
- Configutation with C++ policy advantages:
- dynamic loading of the classes according to (I opened the roof of the car, now I want the configutation to be changed on run-time)
- more freedom to configure
- extendibility
- It would be easier to implement conditional programming (if the roof is open)
- XML configuration file disadvantages:
- So back to the original discussion of this task: we need to check if Android policies are good enough or do we need to extend our own
- But the decision to use XML and C++ policy is a different decision
- There is already a bit of documentation in the implement policy on android
- We need to get a real configuration file to see what it would look like (a simple file but with different examples) such as roof open, driving mode change, etc.
- This is different than the audio focus matrix defined in the multi-zone audio focus. We could modify CarAudioService.java
- We could modify more files but then Andoird would be not certified. There is of course advantages and disadvantages but let's check our options that keeps us certified first.
- We need to check if the Audio Focus matrix is modifiable (check with Unknown User (bartoszbialek))
Discussion about the AVB topic
- as mentioned last week, there are still open points like how do we integrate ALSA devices, how would be do cross ECU communications, etc.
- The problem is, is there something more we can introduce?
- Wassim: imo, there are no longer low hanging fruits in this topic. We either go further or we drop the subject.
- It depends if there is someone that would like to try something and go further
Going futher
- We need to continue with this concept Android and System Level Audio, to check which option is better going further
Looking at the current sprint (AASIG-92)
- audio transfer to external ECU
- There are still some problems with the definition of Offloading
- There are some overlapping and similarties
- There is still a question of considering the Audio HAL as part of Android or not
- The way you control your dsp on the Audio HAL is completely outside of Android
- Piotr maybe meant that since we decided that the audio effect Audio HAL is outside of Android, what are the APIs that we can interact with
- Any android has Audio HAL implementation but the different is that the audio effect HAL expects the audio to be back (not like an amplifier where the audio is just leaving Android and not returning)
- also a good defenition of Offloading would help
- implement Input
- implement Raw Stream extraction
Jira tips
- add components to our epics and stories to diffirentiate them
- create a quick filter on the board for the audio_halContinuation with discussion about the backlog

- 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.
