Rpi VLC

[Belleye]

Hi All,

I'm attempting to push a Raspberry Pi VLC video stream to my google home hub.
test.sh
#!/bin/bash
a="$(date)"
p="/home/pi/tmp/Script_ran_$(date +%F_%R).txt"
echo $a >> $p
timeout 60 cvlc /home/pi/Desktop/test.mp4 --sout '#chromecast' --sout-chromecast-ip=192.168.0.10 --demux-filter=demux_chromecast

Commands.json
{"trigger":"Video background","command":"/home/pi/tmp/test.sh","ground":"background","voice":"video background",allowParams":"false"},

Running test.sh writes the file and pushes the video to the google home hub.
TRIGGERcmd writes the text file but does not start the video

Any help would be greatly appreicated.

Raspberry Pi 3, Raspbian Stretch with desktop (Nov 2018)

@belleye, that's pretty cool. I didn't know you could do that.

I think you're probably trying to run cvlc as root because when you run background commands on a Pi, they run as root.

root@pi:~# cvlc
VLC is not supposed to be run as root. Sorry.
If you need to use real-time priorities and/or privileged TCP ports
you can use /usr/bin/vlc-wrapper (make sure it is Set-UID root and
cannot be run by non-trusted users first).

You can be root and run something as the pi user like this:

root@pi:~# sudo -u pi cvlc
VLC media player 3.0.3 Vetinari (revision 3.0.3-1-0-gc2bb759264)
[00d0b048] vlcpulse audio output error: PulseAudio server connection failure: Connection refused

[00cb2938] main libvlc error: interface "globalhotkeys,none" initialization failed
[00d2fde8] dummy interface: using the dummy interface module...

Also, I like the tags. I think you're the first person who's used them.

@russ, Thanks that sorted it. The MP4 was only to simplify things, the real power comes from linking to a IP camera.

driveway.sh
sudo -u pi timeout 60 cvlc rtsp://192.168.0.11:554/user=xxxxx_password=xxxxx_channel=1_stream=0.sdp?real_stream --sout '#chromecast' --sout-chromecast-ip=192.168.0.10 --demux-filter=demux_chromecast

Now I don't need a nest camera

One last piece in the puzzle, can I share my triggercmd account with my wife's google account? Or do I need 2 RPIs?

I can execute the script from google home, but my wife can't use the service due to not having a triggercmd account.

@belleye, you're probably using Voice Match, so Google Home uses a different Google account depending on who's talking. The issue is you can only have one Google account linked to a TRIGGERcmd account. If you link a second account, it invalidates the previous account's link.

This issue came up before and the best solution seemed to be to use IFTTT like this:

Her Google account triggers an IFTTT recipe with Google Assistant on THIS side, and a Webhook on THAT side, which triggers the command with your TRIGGERcmd token.

@russ Thanks I'm away for a week or more, I'll have a crack when I get back.
