<p class="MsoNormal">Hello All<o:p></o:p></p>

<p class="MsoNormal">I am trying to build an application for the arm board on OpenCV.<o:p></o:p></p>
<p class="MsoNormal">I could successfully cross compile and install the FFMPEG for the arm board. Now when I am cross-compiling OpenCV, it gives me the error that “ffmpeg/videio.h” missing.<o:p></o:p></p>
<p class="MsoNormal">Further debugging this problem I found that ffmpeg changed the format to lib* name and OpenCV had put a Flag check (HAVE_GENTOO_FORMAT or HAVE_FFMPEG_FORMAT) for it. After googling about it, I understood that the flag is by default passed
by FFMPEG code to the OpenCV. Here I am unable to understand how it happens?<o:p></o:p></p>
