I ran a 24x7 live stream at 720p on a pi3, that I also downsampled to 360 and 240 concurrently with hardware via ffmpeg compiled with omx support via nginx-rtmp to HLS. The origin stream was from a hardware HDMI capture out of the pi that I split into the display and there was usually a webcam on in the corner of the screen. The 3 streams whizzed along at 1.0x all day.
