Camera stream
compressed_vipc.py connects to a remote device running openpilot, decodes the video streams, and republishes them over VisionIPC.
Usage
On the device
SSH into the device and run following in separate terminals:
cd /data/openpilot/cereal/messaging && ./bridge
cd /data/openpilot/system/loggerd && ./encoderd
cd /data/openpilot/system/camerad && ./camerad
Note that both the device and your PC must be on the same openpilot commit.
Alternatively paste this as a single command:
(
cd /data/openpilot/cereal/messaging/
./bridge &
cd /data/openpilot/system/camerad/
./camerad &
cd /data/openpilot/system/loggerd/
./encoderd &
wait
) ; trap 'kill $(jobs -p)' SIGINT
Ctrl+C will stop all three processes.
On the PC
Decode the stream with compressed_vipc.py:
cd ~/openpilot/tools/camerastream && ./compressed_vipc.py <ip>
To actually display the stream, run watch3 in separate terminal:
cd ~/openpilot/selfdrive/ui/ && ./watch3
compressed_vipc.py usage
$ python compressed_vipc.py -h
usage: compressed_vipc.py [-h] [--nvidia] [--cams CAMS] [--silent] addr
Decode video streams and broadcast on VisionIPC
positional arguments:
addr Address of comma three
options:
-h, --help show this help message and exit
--nvidia Use nvidia instead of ffmpeg
--cams CAMS Cameras to decode
--silent Suppress debug output
Example:
cd ~/openpilot/tools/camerastream && ./compressed_vipc.py comma-ffffffff --cams 0
cd ~/openpilot/selfdrive/ui/ && ./watch3
