<body class='hmmessage'><div dir='ltr'>Hi to all,<br><br>I was doing some development work and as I was installing Kdenlive from source on another machine, I am unable to compile MLT because of a certain error which, after searching various forums, I have narrowed down to have something to do with FFMPEG, but I am unable to locate a fix.<br>Here is the (hopefully) relevant part of the terminal output.<br>------------------------------------------------------------------------------------------<br>

Hopefully someone knows how to fix this error, as I have tried on other virtual machines and I get the same, following the install guide on the page. Thank you in advance for your help.<br><br>Greg<br> </div></body>
