That is correct. I did that already for the Nexus 4 and pushed patches https://code-review.phablet.ubuntu.com/444 https://code-review.phablet.ubuntu.com/445 https://code-review.phablet.ubuntu.com/446 That enables the basic bits for the media encoding side. On the Nexus 4 the more hard thing is the getting WiFi Direct support working as the WiFi driver we have in the kernel seems to be quite busy. However to highlight the important thing: The Android side source of the MX4 is not available to the public and will not. Only people inside Canonical have access to it. We don't have any plans to enable aethercast on the MX4 and krillin by default. I've shared those patches basically for community ports based on Android 4.x. Also don't expect you're done with just importing those three patches into your tree. Depending on how the encoder is structured and performing there are more changes necessary involving debugging and insight into the whole thing. > Regarding (1) - Meizu released 5.x OS recently.

Changing to a newer BSP requires a two to three month effort for multiple people involved. Not an easy thing and isn't really worth for Ubuntu Touch as we don't gain any new features and will only risk regressions etc. The BSP we have stabilized very much over time so there is absolutely no reason to change to a newer version of Android for the MX4. regards, Simon -- Mailing list: https://launchpad.net/~ubuntu-phone Post to : ubuntu-phone@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-phone More help : https://help.launchpad.net/ListHelp
