[Issue description]
Camera preview always stuck , PreviewStream stop running caused by queueBuffer fail.
[Scenario]
We are trying to implement a v4l2-loopback camera device.
For doing this, we also modified driver to request buffer by using MMAP instead of USERPRT.
Device works but it will crash after few seconds preview.
Please help to solve this issue.
Thanks a lot.
