ffmpeg codec error on audio file
31 juillet 2013, par foosionI 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).
[D:\temp\dl]ffmpeg -i "01 - The Day Begins.m4a" -codec copy day.m4a
