    I have same version of FFMPEG compiled by the same way on another testing machine and there it is working. I tried to recompile/reinstall ffmpeg with the latest version, but result is the same.

    Does someone know what could be wrong on my instance ?
    Thanks.

  • I could not encode using the Intel® Media Server Studio on the ZOTAC ZBOX PI225

    It seems like that something of parameter missing, I think.

    If you have an idea to solve this, let me know.
