Nerijus Bendžiūnas 397ed142ad doc: fix :zephyr-app: paths 
During testing I've found one bad path and looked if
there is more.

I've used this oneliner to find more:

```
rg :zephyr-app: | awk '{ print $3 }' | while read dir
do
    test -d $dir || echo $dir
done | grep '^samples' | grep -v '<' | sort | uniq

```

Video Capture
#############

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

This sample application uses the Video API to retrieve video frames from the
video capture device, writes a frame count message to the console, and then
discards the video frame data.

Requirements
************

This sample requires a video capture device (e.g. a camera).

- :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.

Building and Running
********************

For :ref:`mimxrt1064_evk`, build this sample application with the following commands:

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/video/capture
   :board: mimxrt1064_evk
   :goals: build
   :compact:
