Actually I rebased your pull request in my local repository before 
applying it. Obviously I would not be able to push the rebased branch 
back to your repository.

Hi Scott

Do you have any idea what caused the problem that Klaas had, where he 
could not skip during playback? I was unable to re-create that.

Moving forward from here, I want to start planning for the next ffmpeg 
version. FFmpeg master has advanced a lot since release/4.4 and I think 
it best if we start with that. I attempted to merge FFmpeg master into 
our FFmpeg master and there was a huge number of conflicts. I imagine 
there will be a similar problem if we try to apply your list of commits 
to FFmpeg master. I think they have done a lot of cleanup and 
re-arranging of code into different files.

Perhaps we can maintain a branch in MythTV that runs with FFmpeg master, 
until FFmpeg branch off release/4.5 then we merge it back into our master.

Peter
