||||||
## 2 - Launch viewer
|
|
||||||
# Connect to capture card and display captured images immediately
|
|
||||||
# Send to background so we can initiate the loop below
|
|
||||||
mpv --title="Capture Card" av://v4l2:/dev/video0 --profile=low-latency --untimed &
|
|
||||||
|
|
||||||
## 3 - Connect audio, send to background for loop
|
|
||||||
pacat -r --latency-msec=1 -d $input | pacat -p --latency-msec=1 -d $output &

## 4 - Cleanup
|
|
||||||
# Watch for mpv to exit

|
||||||
while pgrep -f mpv >/dev/null; do
|
|
||||||
sleep 3
|
|
||||||
continue
|
|
||||||
done
|
|
||||||
|
|
||||||

|
||||||
