Failed to start streaming: invalid argument #475

Hey @johnscode, |
yes. using raspi-config, legacy camera support was enabled for this. |
I have the same issue trying to run the |
I've also just started getting this error. I suspect underlying Pi camera driver must have automatically updated because my Go service was working with the camera stream until my Pi was rebooted a couple days ago. The camera stream works fine on my laptop so I think this issue is probably at a lower level than Pion. I will report any further findings here. |
(UPDATE - Please see RPi Forum post here: https://forums.raspberrypi.com/viewtopic.php?t=369927) FWIW, I recently updated libcamera (and rpicam-app), and now I get: whenever I've changed the cropping width/height away from the default. For example, Has anyone had a similar experience? |
Your environment.
What did you do?
Trying to run the jpeg snapshot example from the main Readme:
import (
"image/jpeg"
"os"
)
func main() {
stream, _ := mediadevices.GetUserMedia(mediadevices.MediaStreamConstraints{
Video: func(constraint *mediadevices.MediaTrackConstraints) {
// Query for ideal resolutions
constraint.Width = prop.Int(640)
constraint.Height = prop.Int(480)
},
})
}
example runs fine on OSX. runs to completion on pi when substituting the test drivers in the imports, ie
//_ "github.com/pion/mediadevices/pkg/driver/camera"
_ "github.com/pion/mediadevices/pkg/driver/videotest"
attempt to run using
go run main.go
What did you expect?
successful run producing a jpeg file
What happened?
panic failure at line 28
error is occurring due to the line:
stream, _ := mediadevices.GetUserMedia( ....
If i change it to check the error:
stream, err := mediadevices.GetUserMedia( ....
if err != nil {
fmt.Printf("%+v\n",err)
return
}
error reported is: 'Failed to start streaming: invalid argument'
If I run (with the real driver imported) using: export PION_LOG_DEBUG=all && go run main.go
i get output showing several configurations that match the constraints, with final one shown being 'best fit':

Should point out that this is using an onboard pi camera and not a usb camera.
fwiw:
the onboard camera is accessible using the standard libcamera apis (in cpp).
the blackjack webcam lib works for usb cams on a pi, but not the onboard cam
