<![CDATA[Does voxl-jpeg-turbo use any HW accelleration?]]>If yes great!
If not, are there any options that support hw acceleration for JPEG encoding?

But, string libOmxCore.so only displayed video and audio codec. There is no image codec.

But I would imagine you could locate it in a header file.

I tried use openMAX based on this code https://github.com/tjormola/rpi-openmax-demos/blob/master/rpi-encode-yuv.c

It compiled correctly. But which openMAX component to use? That code is for rPI, so the component is "OMX.broadcom.image_encode". I changed to "OMX.qcom.image_encode" but I got no such component error.

Could you tell me which omx component to use for the jpeg encoding?

Thank you!

Is there a way or a workaround to access it? Otherwise, we are running into overheating issues on the VOXL (both VOXL-Cam and FlightDeck).

So it is all SW. There is HW support for JPEG encoding on the device but we have not yet enabled it.
