We should do that even with the CameraManager then (the current implementation), correct?

Correct. On my Xiaomi devices, there are two invalid cameras ("facing" is "external" and fails to open) that can be filtered by this capability. However, they are hidden in CameraManager.getCameraIdList. I don't know if any OS returns non-backward-compatible cameras from CameraManager

Contrary to CameraManager.getCameraIdList(), shouldHideCamera() is not called. Is it on purpose to show camera that are wrongly hidden?
There was a problem hiding this comment.
Yes. shouldHideCamera was added recently, so for example when a companion device app added a virtual camera, it won't be seen by normal apps, I don't know if anyone is doing that, but it should be interesting to try to include them.
It shouldn't affect Samsung devices, because It will affect Xiaomi devices (#4392 (comment)) and LineageOS (#4392 (comment)) |

While I was making tests for this PR with a Xiaomi Redmi Note 13, I noticed that dc2fcc4 (#5659) already fixes the problem. On On Can you confirm? |

Thank you for your test 👍
Maybe we can keep camera 8 and 9 listed, but without printing the exception (and also disable it for other errors): diff --git server/src/main/java/com/genymobile/scrcpy/util/LogUtils.java server/src/main/java/com/genymobile/scrcpy/util/LogUtils.java

I think cameras 8 and 9 don't work at all, so not worth listing

Thank you, I close this PR since CameraService is not necessary (at least for now). |

This is a cleaned-up version of #4392 (comment).
I'm using similar code in my project to enumerate cameras, then use Scrcpy to mirror them, but recently 2337f52 broke this usage.
I think it should rather list and accept non-functional camera IDs, than rejecting functional ones.
This doesn't include the code to handle logical vs. physical cameras.
