I understand the vendor-customized repo versions can't be supported, 
but I don't even know what command line options would be required to 
repair the files.  I actually already have a set of scripts for quickly 
building and setting up the source version of ffmpeg if the repo 
version doesn't do what I need.

I mainly just need to know if it is possible using ffmpeg (and if so, 
how) to trim everything off the beginning of a video file up to the 
first keyframe.
