Jukka Rissanen 5c3fa85bc8 samples: net: Change to use CONFIG_POSIX_API Change the sample applications that use network socket API to use the POSIX_API config because the NET_SOCKETS_POSIX_NAMES is deprecated. Convert also the zsock_ API calls to plain BSD socket API calls when applicable. Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no>		2024-03-27 13:40:13 -05:00

.. zephyr:code-sample:: video-tcpserversink
   :name: Video TCP server sink
   :relevant-api: video_interface bsd_sockets

   Capture video frames and send them over the network to a TCP client.

Description
***********

This sample application gets frames from a 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/subsys/video/tcpserversink
   :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
