Auto restart hyperHDR instance on error

[bobbanico]

Hello,

I am using HyperHDR on a raspberry pi0 W, and it happens that the USB connection drops, causing HyperHDR to not sync to images anymore.

2021-03-09T14:18:08.384Z [V4L2:/DEV/VIDEO0] (ERROR) Frame index = 54493, inactive or critical VIDIOC_QBUF error in v4l2 driver. Buf index = 1, worker = 0, is_active = 1.
2021-03-09T14:18:08.391Z [V4L2:/DEV/VIDEO0] (ERROR) Throws error nr: VIDIOC_DQBUF error code 19, No such device
2021-03-09T14:18:08.399Z [V4L2:/DEV/VIDEO0] (ERROR) VIDIOC_STREAMOFF error code 19, No such device
2021-03-09T14:18:08.409Z [V4L2:/DEV/VIDEO0] (INFO) Stopped

To solve this i go to the interface and press "Disable Instance" and "Enable Instance" to have it restarting as otherwise it stays in effect mode.

I was wondering, would it be possible to add something like an attempt to restart on errors ?
It would not solve the cause which is dropping USB, but would allow to restart and process the images again.

Thank you !

Hi
Although the workaround is possible but I'm not planning that at the moment to implement it by myself as it's abnormal situation related to the hardware problem and not a software glitch. Probable some power supply issue, please check dmesg.
