SHARED PLANS: Why NUMA-aware allocator (Custom collector settings) – A NUMA-aware allocator enables performance optimization of an application on computers with non-uniform memory architecture (NUMA) by increasing the application's use of lower latency memory. All I can say is that to export an HD jpeg image sequence with a stereo track is taking about 1 sec per frame. I made some attempts with the "-threads" option, but the time remains exactly the same, whichever number of threads I specify. After this I'm not sure if the encoded video is retrieved by the CPU and then piped to ffplay or if it's stays in the GPU and directly displayed on the monitor. I have built a simple media player using ffmpeg on Android 2.
