CameraAccessException / Error configuring streams: Broken pipe

[janusw]

Another exception that I see occasionally with v1.4.7 (apparently when turning off and on the camera too quickly) ...

Android.Hardware.Camera2.CameraAccessException: CAMERA_ERROR (3): endConfigure:766: Camera 0: Error configuring streams: Broken pipe (-32) ---> Java.Lang.RuntimeException: endConfigure:766: Camera 0: Error configuring streams: Broken pipe (-32)

I can also reproduce this issue. Did you find any workaround?

[walnut-co]

any update on this ?

any update on this ?

Unfortunately not. Do you still see this with v1.4.9? And do you have a reproduction procedure to trigger this error?

[walnut-co]

still happens i believe

We have the same problem in a production app.
Here's a link to a discussion I found while googling the problem, apparently a couple of causes for the problem listed - who knows how reliable this info is though.

Add.: There is a claim by our support team that this seems to happen only with Pixel or OnePlus phones. How does this claim match up to any of you guys' experience?
