The V4L2VideoDeviceTest class configures the capture pipeline with parameters that are partly hardcoded, and partly come from the current configuration of the device. In particular, with the vimc pipeline, the sensor subdevice is configured with the size retrieved from the capture video node, and the video node is then reconfigured to 640x480. Relying on the current (and thus possibly random) device configuration can lead to broken pipes when starting streaming. This currently causes failures of the dequeue_watchdog test when run after the formats test. Fix it by explicitly setting the same size for both the vimc subdevs and the video capture device.
