<div>Depends on the version of ffmpeg. I have found that previous to ffmpeg 3.0, setting the decode threads to 4 sped up decoding enormously (on a server class system with 32+ cpu cores running Ubuntu).</div>

<div>Since ffmpeg 3.0 however, we had to revert to setting the threads to 0 on that same system (allow ffmpeg to decide how many decode threads to use) because using 4 decode threads was running too slow.</div>
