As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>. This patch proposes to then include <zephyr/kernel.h> instead of <zephyr/zephyr.h> since it is more clear that you are including the Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a catch-all header that may be confusing. Most applications need to include a bunch of other things to compile, e.g. driver headers or subsystem headers like BT, logging, etc. The idea of a catch-all header in Zephyr is probably not feasible anyway. Reason is that Zephyr is not a library, like it could be for example `libpython`. Zephyr provides many utilities nowadays: a kernel, drivers, subsystems, etc and things will likely grow. A catch-all header would be massive, difficult to keep up-to-date. It is also likely that an application will only build a small subset. Note that subsystem-level headers may use a catch-all approach to make things easier, though. NOTE: This patch is **NOT** removing the header, just removing its usage in-tree. I'd advocate for its deprecation (add a #warning on it), but I understand many people will have concerns. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no> |

VIDEO TCP SERVER SINK
#####################
Description
***********
This sample application gets frames from video capture device and sends
them over the network to the connected TCP client.
Requirements
************
This samples requires a video capture device and network support.
- :ref:`mimxrt1064_evk`
- `MT9M114 camera module`_
Wiring
******
On :ref:`mimxrt1064_evk`, The MT9M114 camera module should be plugged in the
J35 camera connector. A USB cable should be connected from a host to the micro
USB debug connector (J41) in order to get console output via the freelink
interface. Ethernet cable must be connected to RJ45 connector.
Building and Running
********************
For :ref:`mimxrt1064_evk`, build this sample application with the following commands:
.. zephyr-app-commands::
:zephyr-app: samples/video/mt9m114
:board: mimxrt1064_evk
:goals: build
:compact:
Sample Output
=============
.. code-block:: console
Video device detected, format: RGBP 640x480
TCP: Waiting for client...
Then from a peer on the same network you can connect and grab frames.
Example with gstreamer:
.. code-block:: console
gst-launch-1.0 tcpclientsrc host=192.0.2.1 port=5000 \
! videoparse format=rgb16 width=640 height=480 \
! queue \
! videoconvert \
! fpsdisplaysink sync=false
