 I have a client who gave me a mp4 file which encoded fine.  However, she
 had some audio issues with that file and felt that using m4v would solve
 these.  Whether that is the case is neither here or there I suppose.  The
 issue is, the mp4 encoded fine, but the m4v triggered all sorts of errors.

 Is this an issue with the file itself?  The settings or ffmpeg?

 This is the command:

 /usr/local/bin/ffmpeg   -i  /home/finished/1065-1736-audio-turned-down
 .m4v-pre.mov -i /home/titlejobs/uploads/1736-audio-turned-down.m4v
 "[1]scale=1920:-1,pad=1920:1920:0:420.00000[1v];[1v][0]overlay=0:0 "
 -c:v libx264 -profile:v baseline -pix_fmt yuv420p -level 3.1  -y

 And I am attaching the report/log
