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:

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 ```
