2070 #ffplay -f live_flv -fast -x 1280 -y 720 -fflags nobuffer -flags low_delay -strict experimental -vf "setpts=N/60/TB" -af "asetpts=N/60/TB" -noframedrop -i rtmp://url_here
2071 ## a lot of those args arent needed, here is what I ended up with:
2072 # #ffplay -f live_flv -fflags nobuffer -flags low_delay -i rtmp://localhost/live
2073 #
2074 # A problem with rtmp is that it doesn't support vp8/vp9, requiring the partly patent encumbered h264.
