Hi,
I have been trying recently to make a usb-based-webcam device to work with
Linux. The entire scheme is a bit complex:
UVC gadget <--User Pointer--> User-Space Daemon <-- MMAP --> V4L2 capture
device.
The UVC gadget is internally a v4l2 based device supporting VB2_VMALLOC
operations,

Hi Laurent,

Hi Laurent,
I have been doing some experimentation with the UVC webcam gadget along with
the UVC user-space
application which you have written.
The UVC webcam gadget works fine with the user space application handling the
CONTROL events and
providing DATA events. Now, I wish to interface a real

As, the 'video->encode' routines are called with 'queue_irqlock' already held,
so acquiring a 'queue_irqlock' again in 'uvc_queue_next_buffer' routine causes
a spin lock recursion.

We are considering putting an advanced HDMI receiver chip on our SoC,
to allow reception of HDMI audio and video. The chip receives HDMI data
from a host like a set-up box or DVD player. It provides a video data interface
and SPDIF/I2S audio data interface.
