halium-7.1: Disable cameraserver & mediaserver #9
Conversation
Halium-based ports either use droidmedia or camera_service in libhybris for camera needs. This service actively interferes with camera functionality provided by either of them, while hosting an unnecessary Binder interface no one is using. In addition to that it also takes over the socket for the camera trust agent which we don't want. Last but not least, since this racy behavior causes trouble, cameraserver's removal also fixes the Xperia X's infamous "green half" screen in the viewfinder.
mediaserver is an unnecessary Binder service for Halium. Also, it might act as a fallback for providing camera functionality depending on the device's hardening configuration, which would spawn yet another conflicting cameraserver in disguise, replacing the trust agent socket underneath our feet.
…CameraService libcameraservice has multiple consumers, each instantiating their own TrustAgentRegistry and tripping over each other's trust socket on the same path. Don't instantiate the TrustAgentRegistry unconditionally. Instead, just do so for the actual CameraService.

The actual fix for Halium 7.1 not having a stable trust-agent connection depending on a race condition during boot is in eb287ea. I just noticed that the other two reflect 1:! the only other open PR here: #5 Let me know how to proceed with the service disablement changes but the mentioned commit eb287ea is critical in getting camera permissions to work properly. |

With gpu-compositing enabled in QtWebEngine and mediaservice disabled everything works as expected, including H264 decoding. |

Android's default cameraserver actively interferes with camera functionality provided by either of them,
while hosting an unnecessary Binder interface no one is using.
In addition to that it also takes over the socket for the camera trust agent which
we don't want.
Last but not least, since this racy behavior causes trouble, cameraserver's removal
also fixes the Xperia X's infamous "green half" screen in the viewfinder.
To round it up also disable mediaserver as it is an unnecessary Binder service for Halium.
Also, it might act as a fallback for providing camera functionality depending
on the device's hardening configuration, which would spawn yet another conflicting
cameraserver in disguise, replacing the trust agent socket underneath our feet.
