Using Temi's Camera

[mfxuus]

Hi! I'm trying out a few things on Temi, code over here: https://github.com/mfxuus/temi-test/tree/michael

One of the things I wanted to do was to capture fames from the camera (say every 5 seconds or so), and send it off to a server to get it processed. I mostly followed the instructions here: https://developer.android.com/codelabs/camerax-getting-started#3, and things are somewhat working, except for the actual capturing part. Specifically, when I press "Take photo", which triggers the takePhoto function (link), I get the following logs from Temi:

Not sure if it matters, but I'm on Temi V2. That said, on an Android 6 simulator, the preview is messy but after I press take photo, I can at least find the taken photo in the device explorer. Any ideas what could be the issue? I would have assumed that grabbing camera frames is a fairly common use case; do we have any working code / example for it? Finally, ideally I would have just send the file off to the server in-memory/without writing to disk, and I tried various setups with OnImageCapturedCallback but it's also resulting in similar errors on Temi (e.g. timeout for jpeg callback, Dropping jpeg frame., ...). On the simulator it's at least returning some encoded data (though I also haven't got it to work perfectly there).

Any pointers would be greatly appreciated!
