That’s not terribly surprising, FFmpeg seems to be laggier in general:
Unfortunately I can’t edit the old posts in this thread to recommend GStreamer instead myself, and I don’t know that it’s worth badgering the mods about.
Although ffplay is probably only marginally better than using VLC or something - it has a small buffer that you can make smaller with -fflags nobuffer, but any amount of buffering is just avoidable latency in FRC. (So the “tier list” is GStreamer > ffmpeg > ffplay > VLC et. al.)
