Hardware

Device	Connection Method	Screen	USB Device
Raspberry Pi 4 4GB	USB Cable	Chinese 5 inch screen	Chinese RCA-USB adapter

Installation Method: Install.sh

Description of problem:

USB Camera image not displaying on camera page when connect. Only white screen. Overlay disabled. In logs

No suitable resolutions found to fit in QSize(724, 480)

However my camera has 640x480 output. gst-device-monitor-1.0 output:

Device found:

        name  : USB2.0 PC CAMERA

                v4l2.device.driver = uvcvideo
                v4l2.device.card = USB2.0 PC CAMERA
                v4l2.device.bus_info = usb-0000:01:00.0-1.1.4

                v4l2.device.device_caps = 69206017 (0x04200001)
        gst-launch-1.0 v4l2src ! ...

Expected Result:

Camera image displays correctly.

Walkaround:

I've managed walkaround changing the pipeline in the source and recompiling camera.cpp. https://github.com/openDsh/dash/compare/develop...maklimcz:dash:develop#diff-37c4b1554b048ac37e0a46f0275628bb7439221f8338f2f7cc2ea7f877b6ffab

yeah the camera interface has a lot to be desired 🙂 easiest would be to let you type your own in... but I kinda try to minimize keyboard input as much as possible (since not everyone has access to one in the car)

open to suggestions on how we can make this more customizable! (maybe like a "config" mode where more options are exposed? like when setting up your pi on a bench)

A config mode does sound good. Maybe combo boxes with the most common resolutions but also an uploadable config file for custom settings. I'll think on it some more.

i think the best option is to specify whole pipeline command in config file you configure that once and if it works there no reason to change it, unless you replace your camera

openDsh / dash
