2046 # comparing nginx rtmp to icecast
2047 # `mpv --cache=no` had about 2.5 sec latency vs 4 seconds.
2048 # Then I discovered this command which had about .5 sec latency:
2049 #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
2050 ## a lot of those args arent needed, here is what I ended up with:
2051 # #ffplay -f live_flv -fflags nobuffer -flags low_delay -i rtmp://localhost/live
2052 #
2053 # A problem with rtmp is that it doesn't support vp8/vp9, requiring the partly patent encumbered h264.
2054 # Looking at alternative protocols: dash & hls are both high latency, I tested dash with the nginx-rtmp
2055 # module and got about 5 seconds of latency, web results imply that is normal.
2056 #
2057 # Webrtc is what jitsi & bbb use, but an annoying thing is that
2058 # generally requires a web browser with javascript, or some special
2059 # client, and afaik, it has a smaller limit on number of clients.
