and i get the following error and it failed to mix audio and video
WARNING: Your copy of avconv is outdated, update avconv to version 10-0 or newer if you encounter any errors.
I have tried the solution given in avconv version and youtube-dl by mchid
and Avconv warning while downloading YouTube video by user35186
, still the problem has not been solved and now it shows
WARNING: Your copy of ffmpeg is outdated, update ffmpeg to version 1.0 or newer if you encounter any errors.
