This repository is for debugging simplified use cases for Snapdragon Flight Linux Camera API

Use-cases that are being debugged

Multi-process

• This successful test operates 4K and optic flow cameras in separate processes
• This should complete with no asserts or red errors

remote, over adb

make test_multiproc

native

./main_optic &
./main_hires

Single process, accessing camera API in main thread

• This test, which tries to take a picture using the 4K camera while optic flow preview callbacks are occuring, fails.

remote, over adb

make test_main_simul

native

./main_simul

Overall use case: optic flow and 4K camera simultaneous capture

• optic flow camera onPreviewFrame callbacks always on
• 4K camera takePicture intermittently
• 4K camera startRecording and stopRecording intermittently

Code design / classes

• One class for 4K camera, one for optic flow camera
• Both declared at global scope (doesn't seem to matter)

Makefile

Environment (cross-compiling)

• Make sure HEXAGON_SDK_ROOT and HEXAGON_ARM_SYSROOT are defined
• Run make

Environment (native)

• no special setup needed

adb push ../sdflight-cameras /home/linaro/sdflight-cameras
adb shell
cd /home/linaro/sdflight-cameras
make
