Sorry I did it too much of a hurry.
It's not about -lavcodec but -lavutil and it's better to swap
$FFMPEG_LIBS and -lavutil this way:
from this:
FFMPEG_LIBS="$FFMPEG_LIBS -lavutil"
to this:
FFMPEG_LIBS="-lavutil $FFMPEG_LIBS"

This way -ldrm is contained in $FFMPEG_LIBS, after -lavutil(the library 
which needs -ldrm).

I wait for other comments before submittin v3.

Sorry again

Best regards
