    the tutorial code was update to work on new ffmpeg versions.I’m using VM Ubuntu 16.0.4 64 bit fresh install on windows 10 host.

    so why I’m having all of these errors ?

    Update :
    I moved to Ubuntu 12.04 VM and ffmpeg 0.11, I instilled it with opencv 2.4.2 here is the link . This should work yet i don’t why I’m having hard time compiling such small program.

    Update2

    I changged avcodec_free_frame to av_free and the file complied

    Dranger code is old

    Update 3
    i downloaded ffmpeg 1.0.10 which has the same library version that is the tutorial tested on. Everything complied without any problem now.
