• ffmpeg codec error on audio file

  31 juillet 2013, par foosion

  I have some m4a files that will not play properly using the google music player app on my Android phone, although they play fine on most everything else. I thought the problem was the container and thought "ffmpeg -i bad.m4a -codec copy good.m4a" might help. However, when I run on the problem files, I get error messages. Running this command on non-problem files has not generated error messages.

  Please suggest ways to fix (other than re-encoding).
