Raspivid and Node Red

I'm trying to work with raspistill and raspivid and am getting an odd error I can seem to work around.

raspistill is working but taspivid gets an error on file not found.

I even wrapped it all in a shell script and it works when I call it from the shell as root or pi.

#!/bin/bash
/usr/bin/raspivid -t 30000 -w 570 -h 570 -fps 25 -b 1200000 -p 0,0,570,570 -o /tmp/video.h264
/usr/bin/MP4Box -add /tmp/video.h264 /home/pi/Desktop/video.mp4
rm /tmp/video.h264

What would be great is if we could pull the cmd string into the ui_media

flows.json (3.6 KB)

Forgot how to get the flow to display correctly, so I uploaded it.

Go to a new line, click the </> button and paste it where indicated. Please do that with for us so we don't have to download the file, which is a pain. Thanks.

Also please show us the full error message.

Here is the error.

Its as if node-red doesn't have permission to access the camera. I checked and it should.

Can you open a terminal and stop and restart node-red and post the startup messages please. You should be able to do that by running
node-red-stop
node-red-start
Is that you you normally run node-red?

I want to see the node red startup log please. node-red-start should do that assuming you installed using the recommended technique.

Node Red is run as a service on a Raspberry Pi 4 running "LATEST" code Buster/Debian

I think there is a startup option to bump up the logging.

I turned up debug, stopped, started, and ran command to trigger error.

I can't see anything there that might be a problem. As you said earlier it is as if you can't connect to the camera. You haven't got something else connected to it already have you? Perhaps try a reboot and try it before doing anything else.
Other than that I don't know. Maybe ask on a pi forum what might cause that error with raspivid.

No we can run the command as pi and it works. But node-red cant seem to run the command in an exec node. Makes no sense.

And node-red is run as pi user

Remember, I never have an easy problem....

I'm hoping @dceejay sees this and chimes up. :slight_smile:

Maybe I can set logging to see the error. Error code 127 seems ode to me though.

When you run it in a terminal is the display connected to the pi? I wonder if it doesn't work if it is not running in a session with a display. Can you connect to the pi via ssh and run the command like that?

Try adding DISPLAY=:0 to the front of the command, but that is just a wild guess and anyone who knows what they are talking about will probably laugh at the suggestion.

Error code 127 returned, when using the bash shell which is the default on raspberry pi, usually means command not found. Can you use an exec node and see what happens if you give the command ls -ahl /usr/bin/raspivid and what it returns in permissions and all there? A different option is that there's part of the command it can't fully understand or that a file referenced in it can't be found, or a script/library underneath it. With the idea that it works from a script, those sound unlikely as reason.
Oh, and take a look at /tmp/ and see if there's already a video.h264 there, and if so which user owns it, and if the pi user has permission to that file.

Why is Video Capture at the start of the command the exec node is trying to execute?
In this case dash is trying to execute a program/script called Video in your path which it cant find. Shouldn’t your command start with /usr/bin/raspivid or even just raspivid? Am i misunderstanding something here?

nodered actually calls exec scripts with dash not bash right now on raspberry pis as this is what raspberry pi os symlinks from /bin/sh/ and this in turn is what node.js uses.
There is actually a pull request merged already which should change this for the exec node soon and make use of bash if its there as there were a few problems with how node.js child process and dash interacted.

That is the name of the exec node I believe. However, the error Video: not found might indicate that it is trying to run a command called Video for some reason.

@vlturner can you post exactly the flow that generates that error please? Using the </> button.

I thought Video capture was part of the error message, but that explains the exact thing... And the whole Video not found would explain the error 127 because Video is not a known command. Spot on!

Found it:

{
    "id": "ac7596c1.99aee",
    "type": "exec",
    "z": "1591fded.581fe2",
    "command": "Video Capture",
    "addpay": false,
    "append": "/usr/bin/raspivid -t 30000 -w 570 -h 570 -fps 25 -b 1200000 -p 0,0,570,570 -o /tmp/video.h264",
    "useSpawn": "false",
    "timer": "90",
    "oldrc": false,
    "name": "",
    "x": 700,
    "y": 240,
    "wires": [
        ["ee9b8c23.f45c4"],
        ["ee9b8c23.f45c4"],
        ["ee9b8c23.f45c4"]
    ]
}

The command in the exec node is Video capture, so it is configured wrong. The parameters/actual command are appended.

For comparison, here's the raspistill command from the same flow:

{
    "id": "6e5e2f42.183ba8",
    "type": "exec",
    "z": "1591fded.581fe2",
    "command": "raspistill",
    "addpay": false,
    "append": "-vs -ex night -w 570 -h 570 -o -",
    "useSpawn": "false",
    "timer": "",
    "oldrc": false,
    "name": "",
    "x": 660,
    "y": 120,
    "wires": [
        ["4f40679e.837c9"],
        [],
        []
    ]
}

which is set up correctly, and does work okay.

No i just tested with an invalid command and it is how i think it was the exec node with this output was actually trying to run the literal command:

Video Capture /usr/bin/raspivid -t 30000 -w 570 -h 570 -fps 25 -b 1200000 -p 0,0,570,570 -o /tmp/video.h264

Edit as @afelix just also pointed out in the json of the exported flow

Thank you all kind sirs....I think this will be useful for those trying to pull in videos. We do need to write a node to do all this mp4 wrapper stuff and camera options...

Hint...Hint...@dceejay....:wink:

I'm just up to my ears in patent and grant paperwork...

Will know in 8 days as to my chance at $50K

still not a sir
Regardless, to fix it try setting the properties of your raspivid node to match those of your raspistill node. Set the values for command and append correctly and retry, see if it changes.
