User-space applications can use the VIDIOC_REQBUFS ioctl to determine if a
memory mapped, user pointer or DMABUF based I/O is supported by a driver.
For example, GStreamer attempts to determine the I/O methods supported by
the driver by doing many VIDIOC_REQBUFS ioctl calls with different memory
t
The driver try_fmt handler prints a message each time that the image
size has been changed due the maximum and minimum width and height.
Since user-space can try different format and sizes, this logs a lot
of unnecessary messages. Change the message log level to debug and
while being there, also a
The driver exposes 32-bit A/XRGB 8-8-8-8 as supported format but testing
shows that using this format produces frames with wrong colors. The test
was done with the following GStreamer pipeline:
$ gst-launch-1.0 videotestsrc num-buffers=20 ! video/x-raw,format=UYVY \
! v4l2video3convert ! video/x-r
The driver don't take into account the differences between packed, semi
planar and multi planar formats when calculating the pixel format bytes
per lines and image size values. This makes GStreamer to fail when the
following formats are used NV12, NV21, NV16, NV61, YV12, I420 and Y42B:

Hello,
This patch series contains a cleanup and some fixes for the exynos-gsc
driver. I found these issues when trying to use the driver with the
GStreamer v4l2videoconvert element. I wasn't able to display to Exynos
DRM/KMS driver and only a small set of formats were working correctly.
After the
Introduce managed versions of both functions.
They allows to simplify the error path in the probe function of
rc drivers, and usually also to simplify the remove function.
New element managed_alloc in struct rc_dev is needed to correctly
handle mixed use, e.g. managed version of rc_register_device
Simplify the remove function and the error path in the probe function by
using the managed versions of rc_allocate_device and rc_register_device.

Some devices have invalid baSourceID references, causing uvc_scan_chain()
to fail, but if we just take the entities we can find and put them
together in the most sensible chain we can think of, turns out they do
work anyway. Note: This heuristic assumes there is a single chain.
Hello Nikolaus,
