I tested  output_example  with my debugger weeks ago and I wrote the 
results in the ML...
I proposed to add some lines in  output_example.c  after the line  
av_write_trailer(oc) :
    if (video_st)
        av_free(video_st->codec);
    if (audio_st)
        av_free(audio_st->codec);
With this changes here (and in some other encoders' file) my debugger 
says it's ok (no leaks)
