Crystal Sky - speed and video decoding - need faster device #27

Open Djacob502 opened 6 years ago

Djacob502 commented 6 years ago

Could we request a faster crystal sky device to handle video decoding? Any chance we can get a crystal sky device build around the snapdragon 845 chip?

I put an app on crystal sky using the decoding which passes the frames to openCv, does some object recognition, and then displays the frame.

The program works on the 7.87" crystal sky device. However even doing a small amount of processing in openCv, the frames turns green because the device is too slow to quickly complete all the processing.

I'm trying to figure out how to get a clean display. We want to transition to only using crytal sky devices for our apps for a number of reasons. As a comparison - using the nVidia k1 shields works without slowing down the app.

Could the sample decoding app be expanded to include some openCv processing that also works quickly enough on a crystal sky device?

Thanks
