Dtshd, TrueHD won't work with N Api. Google missed to include support for it, we are in contact with them.


RE: Passthrough Changes with v17 - fritsch - 2016-10-04

For TrueHD it is decoder to 8 channels pcm, which the hw fails to open properly. Please enable debuglogging, so we can see.

GetMinimum returns a huge buffer, for everything. How do you compute that in the fw?

Can you perhaps point in https://android.googlesource.com/ where/how they do it?
I can then try to find the method they use in my firmware.
It is a bit technical, so maybe I will need help from the manufacturer next week as they might know better if I don't find it.

Just downloaded latest nightly. Been having issues with audio delay with pass through enabled on SPMC. No issues with v17.

I just noticed in the changelog for Krypton Beta 3, this line.

'Workaround amlogic passthrough on devices running Android 5'

Can anybody elaborate further on what the workaround is and what element(s) of passthrough issues is resolves?

User should not get noise, that's all about it.

Thank you.

And besides that, every AML box should get what it supports, including AC3, EAC3, DTS, DTS-HD, TrueHD (but this is a side effect, the future android devs will hate me).

All AML users with Android 6 and later get what the official API supports.

Please keep us updated if something is heard back from Google for IEC61937 or if they plan to make a new API for eg. Android 'O' that can be backported to Android firmwares and also be used by Kodi.

Any issue found? Or have you achieved to passthrough all the audio format on AML android M system?


RE: Passthrough Changes with v17 - fritsch - 2016-10-11

Implementation is ready and working on capable Android devices. Everything else not working is a Firmware bug :-)


RE: Passthrough Changes with v17 - Cozmo85 - 2016-10-12

What does this mean for Android TV devices? Will things like the mi box ever get proper passthrough or is it up to the manufacturer of the device?


RE: Passthrough Changes with v17 - fritsch - 2016-10-12

Up to the manufacturer. We speak THE documented Android api.
