Another enhancement: animate the changes between frames. Interpolate position, color, other attributes.
Okay. I'm using gstreamer's `v4l2src`, so I'm not really sure from whence this ioctl comes. But that's at least something to go on.
One observation: pixel formats are four char codes, and 0x4f454854 corresponds to ('T', 'H', 'E', 'O') ... which seems suspicious (is something trying to send the string "THEORA" instead of...
I've been playing around a bit, and I can reproduce the condition at will by installing `gstreamer1.0-tools` into the container, and then simply running `gst-inspect-1.0 v4l2src`. In other words, I...
The ultimate cause seems to be by perfomring the `VIDEOC_ENUM_FMT` ioctl on `/dev/video14`. An easy way to trigger this via `v4l2-ctl` available from the `v4l-utils` package: `v4l2-ctl -d /dev/video14 --all`...
This is the line in the gstreamer source which triggering our bug: https://github.com/GStreamer/gst-plugins-good/blob/1660c4d9141f38c26ababca89fb0b893190ecb33/sys/v4l2/gstv4l2.c#L78, which is called from here: https://github.com/GStreamer/gst-plugins-good/blob/1660c4d9141f38c26ababca89fb0b893190ecb33/sys/v4l2/gstv4l2.c#L165, And note that it does filtering to try not to call...
I was able to patch `libgudev` to allow for blacklisting the offending video devices. This seems to have stopped both the kernel warning and also to have improved the stability...
