CameraX fast image capture

[Canberk Güllüoğlu]

Hi,

Is it possible to capture an image every 0.1 seconds using CameraX? I've implemented a handler to trigger image captures at this interval, and it appears that the capture requests are being sent successfully. However, the actual image capture process takes longer than 0.1 seconds, causing subsequent requests to accumulate and introducing significant delays. Is CameraX suitable for this specific use case? I implemented the same use case with Camera2. Thanks.

Hi Canberk -

When you say 'capture an image', what are your constraints? Do you need JPEG at maximum resolution, or are you fine with YUV or lower resolutions?

What kind of configuration did you use in camera2, for reference?

Thanks!

Hi,

Thanks for the quick reply. 

In my camera2 implementation, I have 2 channels (YUV) that I capture from, one is max resolution(4000x3000) and the other is 720p. I take approximately 1 max res photo a second and take 9 720p a second. 

I tried to imitate this approach in CameraX with a handler but I couldn't capture fast enough.(The request is sent but it gets in the queue and waits for the other capture process to end and at the end, there are a lot of delays.)

 I don't really have any specific format constraints.
