Fuchsia Camera Gym (camera3 config exerciser)

Example app to exercise the various stream configurations available for Sherlock.

How To Select Config


How To Run (from fx shell while a Session is running)

This method will not allow passing of command line arguments. All that can be done is to start running camera-gym.

sessionctl add_mod fuchsia-pkg://

How To Run (from fx shell without a Session running)

This method will allow command line arguments. Arguments can be specified as shown below.

How To Shutdown Session

fx shell basemgr_launcher shutdown

How to Run (using present_view)

fx shell present_view fuchsia-pkg:// [ args ... ]

How to Run (using tiles_ctl)

fx shell tiles_ctl start fx shell tiles_ctl add fuchsia-pkg:// [ args ... ] fx shell tiles_ctl stop

How to Restart Session

fx shell run basemgr.cmx

How to Run Manual Mode

camera-gym-ctl accepts lists of commands and sends them, one at a time, to camera-gym. camera-gym must be started in manual mode. (Use “fx camera-gym --manual”.)

There are short scripts that run these configs + streams in cycles:

How to Run Manual Mode Without Session

camera-gym can be started in manual mode without a session running:

fx shell present_view fuchsia-pkg://

How to Run Manual Mode Scripts

Running this bash script will cycle through all configs and all streams forever.

How to turn text descriptions on/off

Turn off descriptions

fx shell camera-gym-ctl --set-description=0

Turn on descriptions

fx shell camera-gym-ctl --set-description=1

How to Capture a Frame in Manual Mode

Caveat (b/200839146): The current frame capture feature only works while a single stream is running. Trying to do so with multiple streams running at the same time will result capturing from a stream randomly selected from all of those running.

Capture a frame

fx shell camera-gym-ctl --capture-frame=0

Review how many frames were captured

fx shell ls /data/r/sys/r/session-0/

Copy out frames that were captured

cd /my_dest_dir/. fx scp “[$(fx get-device-addr)]:”/data/r/sys/r/session-0/* .
