AV1 video codec support improvements New HLS. Still - it does show that using the -threads option can increase performance so run some tests on your particular machine at different levels to find your setups sweet spot. As always, this release is again packed with many new features, bug fixes and other improvements. I may tweak that and see if that changes anything. It could have been a memory issue too - it only had 1GB assigned to the VM. For my setup specifically, using the -threads 6 (on a 12 core machine) resulted in the best FPS when converting the video (from h264 to x264 at a different bitrate to force a conversion) and returns actually diminished the more threads I threw into it. It is the latest stable FFmpeg release from the 2.8 release branch, which was cut from master on. Using anything else resulted in another spread-load situation.Īs you can see, there's also a point of diminishing returns, so you'd have to adjust the -threads option for your particular machine. FFmpeg 2.8.22 'Feynman' 2.8.22 was released on. Using 1 thread did exactly that, loaded one core at 100%.

Using no -threads option wound up at the 130fps range with load spread out across all cores at a low-load level. The interesting part was the CPU loading (using htop to watch it). Thread option/Conversion Rate (fps 60 secs) (none/default)/130fps I was playing with converting in a CentOS 6.5 VM (Ryzen 1700 8c/16t - vm assigned 12 of 16 cores).Įxperiments with 480p movies netted the following:
