Are the slow motion samples working on your device?

[rodrigomologni]

Hello, developers! 👋

The Camera X - Slow Motion and Camera2 - Slow Motion samples are not working on my Samsung Galaxy A53, which should support high-speed capture. Could someone test them on their physical device, please? Thanks in advance for the help. 🙏

I'm running PR #638.

CameraX - Slow Motion shows the following message:

"This device's camera doesn't support high-speed (slow-motion) recording."

Camera2 - Slow Motion doesn't show a preview (black screen) and throws the following error when starting the recording:"

The reason why the CameraX - Slow Motion example is not working on my Samsung Galaxy A53 is found in the "A Note on Device Support" section of the article High-Speed Capture and Slow-Motion Video with CameraX 1.5.

PR #641 fixes the Camera2 - Slow Motion sample to run on the Samsung Galaxy A53.

[rodrigomologni]

The Samsung Galaxy A53 is a mid-range device with a LIMITED hardware support level, which might lack full support for high-speed capture sessions (CONSTRAINED_HIGH_SPEED_VIDEO). I think that's why the Camera2 - Slow Motion sample is failing on it and needs these modifications to run. 😐
