Sensor.alloc_extra_fb returned error when using JPEG and VGA snapshot

Hi. I try to create a clone of the snapshot image and process it instead so don’t modify the original and save it to display. It works fine if I set the sensor with the RGB565 and QQVGA settings, but when I bumped to JPEG and VGA, it returned the error “OSError: Image is not mutable!” like in this photo. Do you have any idea how to fix this issue? Thanks in advance.

Hi, it’s because we have no support for JPEG/Bayer decoding. I have adding support for this stuff coming soon this year. Once it lands you’ll be able to do more stuff with JPEG/bayer images than just displaying them.

Hi. Thanks a lot for clearing that out. it sounds great and I’m looking forwards to it.
