vacuumstreamer

This is a project to stream video from the Ava vacuum cleaner using the video_monitor binary and go2rtc.

Tested on: Dreame L10s Ultra.

Build

docker build -t vacuumstramer .
./run.sh make

Install vacuumstreamer

Copy the vacuumstreamer.so, video_monitor, and configuration files to the vacuum robot:

ssh root@${VACUUM_ROBOT_IP} "mkdir -p /data/vacuumstreamer"
scp -O vacuumstreamer.so root@${VACUUM_ROBOT_IP}:/data/vacuumstreamer/vacuumstreamer.so
scp -O dist/usr/bin/video_monitor root@${VACUUM_ROBOT_IP}:/data/vacuumstreamer/video_monitor
scp -Or dist/ava/conf/video_monitor/ root@${VACUUM_ROBOT_IP}:/data/vacuumstreamer/ava_conf_video_monitor

Install go2rtc

Run on the vacuum robot:

curl -L https://github.com/AlexxIT/go2rtc/releases/download/v1.9.9/go2rtc_linux_arm64 -o /data/vacuumstreamer/go2rtc
chmod +x /data/vacuumstreamer/go2rtc

Persistent configuration

On the vacuum robot, run the following commands to configure vacuumstreamer on startup:

# workaround for missing certificate bug, see https://github.com/tihmstar/vacuumstreamer/issues/1 for details
cp -r /mnt/private /data/vacuumstreamer/mnt_private_copy && touch /data/vacuumstreamer/mnt_private_copy/certificate.bin

cat <<EOF >> /data/_root_postboot.sh

if [[ -f /data/vacuumstreamer/video_monitor ]]; then
    mount --bind /data/vacuumstreamer/ava_conf_video_monitor /ava/conf/video_monitor
    mount --bind /data/vacuumstreamer/mnt_private_copy /mnt/private
    LD_PRELOAD=/data/vacuumstreamer/vacuumstreamer.so /data/vacuumstreamer/video_monitor > /dev/null 2>&1 &
    /data/vacuumstreamer/go2rtc -c '{"streams": {"tcp_magic": "tcp://127.0.0.1:6969"}}' > /dev/null 2>&1 &
