Comment (by dericed):

 Here's a failing command line that would profit. When I use -f framemd5
 the default is that only the first video and first audio track are used in
 framemd5. To include all the tracks in the framemd5 output, I can use -map
 0 to do this (easier than adding lots of -newaudio and -newvideo). But
 data tracks don't work in -f framemd5.
