compressed_vipc.py
connects to a remote device running openpilot, decodes the video streams, and republishes them over VisionIPC.
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.
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
```
