I am live streaming a Camera via RTMP to a Nginx RTMP server like so:
ffmpeg -rtsp_transport tcp -i rtsp://user:[email protected]/ -f image2 -stream_loop -1 -re -i /tmp/overlay.png -filter_complex "overlay" -vcodec libx264 -preset ultrafast -profile baseline -pix_fmt yuv420p -an -f flv -rtmp_live live -s 1280x720 rtmp://remote.server.com:1935/show/stream

I proxy this setup through a running Apache server which already has valid SSL certificates. I can access the stream like this via VLC without issue. https://myserver.com/CameraName/hls/stream.m3u8

This works on every device I have tested it on EXCEPT the iPhone. Which is the most important platform for it to work on. On the iPhone the stream just loads forever without displaying anything. The debugger shows that the device is downloading the .ts files correctly. Interestingly the stream will load about 10% of the time if I pop it fullscreen and fast forward the stream. The timestamp on the player shows something way off when this happens. Something like -11:21:42. I suspect this issue may have something to do with the PTS being fed from ffmpeg.
Apples mediastreamvalidator CLI tool shows that some of the .ts files are being kicked back as 404. But I have not been able to reproduce this on any browser debugger. Any help is greatly appreciated :)

I solved this issue by moving away from Nginx entirely and using node-media-server instead
