[FFmpeg-user] [swscaler @ 0xa533860] Warning: data is not aligned!

[Rev. Fr. Robert Bower]

When I try to do screen capture with audio I receive the following error 
message.

[swscaler @ 0xa533860] Warning: data is not aligned!
Here is the command I am using
/home/frrobert/bin/ffmpeg -f alsa -ac 1 -i pulse -f x11grab -r 25 -s 
1360x768 -i :0.0+0,0 -acodec pcm_s16le -vcodec libx264 -preset ultrafast 
-threads 0 output.mkv

  I am compiling everything from source and redownloaded and recompiled 
today and same error.

Here what I am running

Any idea on how to avoid the error?
