# 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
|
|
```
|
|
$ python3 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
|
|
```
