 ## TRANSCODING USING FFMPEG EXEC ##
 ## EXEC - Many things are possible using exec. To learn more visit https://github.com/arut/nginx-rtmp-module/wiki/Directives#exec   ##
 ## You can either set this here, so all the incoming streams to /live/* get transcoded, or you can push to a seperate recorder app. ##
 ## The following lines will take our incoming RTMP stream and transcode it to several different HLS streams with variable bitrates  ##
 ## This ffmpeg command takes the input and transforms the source into 4 or 5 different streams with different bitrate and quality.  ##
 ## 4 or 5 different streams with different bitrate and quality. P.S. The scaling done here respects the aspect ratio of the input.  ##
 ## If you enable adaptive bitrate streams here, make sure to disable the stream-push to /hls below, under # STREAM RELAYING LOCAL # ##
 #exec ffmpeg -i rtmp://localhost/$app/$name  -async 1 -vsync -1		## Transcoding can be enabled here, or by using the abshls application below.

 ## SET ACCESS RULES FOR APPLICATION /live  ##
 ## PUBLISHING ##
 allow 127.0.0.1;		# If you decice to harden these rules, it is adviced to uncomment this line.
 # allow publish 192.168.2.0/24;	# Anybody from this local IP address range can stream to this application.
 # allow publish 192.168.2.50;	# Allow a single IP address to stream to this application (multiple lines with different ip's are possible)
 allow publish all;		# Anybody from any location can stream to this application. Comment this out if you want to use deny publish.
 # deny publish 10.0.0.50;	# Deny this specific IP address from streaming to this application. Can also be an IP address range.
 # deny publish all;		# Nobody can stream to the server except those that you've set in previous lines.
 ## PLAYING  ##
 allow play 127.0.0.1;		# Localhost can play the stream from this application. Must be set if you decide to use push later on!
 allow play 192.168.2.0/24;	# Anybody in this IP range can play the RTMP directly.
 allow play all;			# Anybody can play the RTMP livestream directly. Comment this out if you decide to use the next option.
 # deny play all;		# Nobody can play the RTMP stream except those that we've set in lines above it.
 ## RECORDING SETTINGS FOR /LIVE ##
 record off;			# off|all|audio|video|keyframes|manual. These options sorta speak for themselves.
 record_path /var/livestream/recordings;	# Folder location that will be used to store the recordings. YOU SHOULD CHANGE THIS TO YOUR PREFERENCE!
 record_suffix -%d-%b-%y-%T.flv;	# Added to recorded filenames. Example uses 'strftime' format results: -24-Apr-13-18:23:38.flv. Default=.flv
 record_unique on;		# on|off. Appends timestamp to recorded files. Otherwise the same file is re-written each time. Default=-off
 record_append off;		# on|off. When turned on recorder appends new data to the old file with no gap. Default=off
 record_lock off;		# on|off. When turned on recorded file gets locked with 'fcntl' call. Default=off.
 record_notify off;		# on|off. Toggles sending "NetStream.Record.Start" and "NetStream.Record.Stop" status messages. Default=off.
 # record_max_size 128K;		# Set maximum file size of the recorded files. No default.
 # record_max_frames 200;	# Sets maximum number of video frames per recorded file. No default.
 # record_interval 15m;		# Restart recording after this number of (milli)seconds/minutes. Zero means no delay. Default=off.
 # recorder name	{}		# Create recorder{} block. Multiple recorders can be created withing single application. Example:
 recorder audio {
 record audio;
 record_suffix .audio.flv;
 record_path /var/livestream/recordings/audio;
 }
 ## This will automatically convert your .flv recordings to mp4 when the stream/recording is stopped. WARNING! This will cause high CPU usage!! ##
 # exec_record_done ffmpeg -i $path -f mp4 /var/livestream/recordings/$basename.mp4;
 ## RELAYING ##
 ## PULLING STREAMS ##
 ## For more info please visit:	https://github.com/arut/nginx-rtmp-module/wiki/Directives#relay ##
 ## pull url [key=value]*	# Creates pull relay. A stream is pulled from remote machine and becomes available locally. ##
 ## URL Syntax:			[rtmp://]host[:port][/app[/playpath]] ##
 # pull rtmp://cdn.example.com/live/ch?id=1234 name=channel_a;		# This is an example. Visit above url for more info.
 # session_relay off;		# on|off. On=relay is destroyed when connection is closed. Off=relay is destroyed when stream is closed. Default=off.
 ## PUSHING STREAMS ##
 ## Push has the same syntax as pull. Unlike pull, push directive publishes stream to remote server. ##
 ## This will push the stream from incoming /live application to these below to create HLS and/or Dash streams, or to record or transcode automatically. ##
 ## Only enable HLS push if you are not using ABS options earlier or by using the encoder application ##
 push rtmp://localhost/hls;		# Remember to enable an app called HLS! Disable it if you use transcoding using variable bitrates.
 push rtmp://localhost/dash;		# Remember to create the app dash! It is safe to disable this if you're not interested in using Dash.
 ## PUSH TO TRANSCODER APPLICATION ##
 # push rtmp://localhost/encoder;	# Enable this if you're not using the ABS options earlier but want to use a different application for it.
 ## PUSH TO RECORDER APPLICATION ##
 # push rtmp://localhost/recorder;	# Enable this if you want to record your stream and convert it to MP4 automatically when you stop the stream.
 ## STREAM RELAYING TO EXTERNAL PARTY'S ##
 ## Push can also be used to re-stream your stream to other platforms. You can do this directly or use an additional application for this. ##
 ## Using an additional local application allows you to set up variables if you prefer. Or you can choose to push to 3rd party directly. ##
 ## YOUTUBE PUSH OPTIONS ##
 # push rmtp://localhost/youtube;	# Uncomment this to use application on localhost (MUST BE SPECIFIED). OR simply use the following line:
 # push rtmp://a.rtmp.youtube.com/live2 /YOUR-LIVE-STREAM-KEY;	# Your RTMP stream will be pushed as it is to Youtube as an RTMP stream.
 ## TWITCH PUSH OPTIONS ##
 # push rmtp://localhost/twitch;		# Uncomment this to use application on localhost (MUST BE SPECIFIED). OR simply use the following line:
 # push rtmp://live-ams.twitch.tv/app /live_YOUR-LIVE-STREAM-KEY;	# Your RTMP stream will be pushed as it is to Twitch as an RTMP stream.

 ## HLS_VARIANT - Used for variable bitrate streaming. Please read: https://github.com/arut/nginx-rtmp-module/wiki/Directives#hls_variant ##
 ## When hls_variant suffix is matched on stream name then variant playlist is created for the current stream with all entries specified by hls_variant
 ## directives in current application. Stripped name without suffix is used as variant stream name. The original stream is processed as usual.
 ## Optional parameters following the suffix are appended to EXT-X-STREAM-INF in m3u8 playlist. See HLS spec 3.3.10. EXT-X-STREAM-INF for full list.
 #	hls_variant _low BANDWIDTH=288000;	# _low		- Low bitrate, sub-SD resolution

	## RELAYING ##
	## PULLING STREAMS ##
	## For more info please visit: https://github.com/arut/nginx-rtmp-module/wiki/Directives#relay ##
	## pull url [key=value]* # Creates pull relay. A stream is pulled from remote machine and becomes available locally. ##
	## URL Syntax: [rtmp://]host[:port][/app[/playpath]] ##
	# pull rtmp://cdn.example.com/live/ch?id=1234 name=channel_a; # This is an example. Visit above url for more info.
	# session_relay off; # on\|off. On=relay is destroyed when connection is closed. Off=relay is destroyed when stream is closed. Default=off.
	## PUSHING STREAMS ##
	## Push has the same syntax as pull. Unlike pull, push directive publishes stream to remote server. ##
	## This will push the stream from incoming /live application to these below to create HLS and/or Dash streams, or to record or transcode automatically. ##
	## Only enable HLS push if you are not using ABS options earlier or by using the encoder application ##
	push rtmp://localhost/hls; # Remember to enable an app called HLS! Disable it if you use transcoding using variable bitrates.
	push rtmp://localhost/dash; # Remember to create the app dash! It is safe to disable this if you're not interested in using Dash.
	## PUSH TO TRANSCODER APPLICATION ##
	# push rtmp://localhost/encoder; # Enable this if you're not using the ABS options earlier but want to use a different application for it.
	## PUSH TO RECORDER APPLICATION ##
	# push rtmp://localhost/recorder; # Enable this if you want to record your stream and convert it to MP4 automatically when you stop the stream.
	## STREAM RELAYING TO EXTERNAL PARTY'S ##
	## Push can also be used to re-stream your stream to other platforms. You can do this directly or use an additional application for this. ##
	## Using an additional local application allows you to set up variables if you prefer. Or you can choose to push to 3rd party directly. ##
	## YOUTUBE PUSH OPTIONS ##
	# push rmtp://localhost/youtube; # Uncomment this to use application on localhost (MUST BE SPECIFIED). OR simply use the following line:
	# push rtmp://a.rtmp.youtube.com/live2 /YOUR-LIVE-STREAM-KEY; # Your RTMP stream will be pushed as it is to Youtube as an RTMP stream.
	## TWITCH PUSH OPTIONS ##
	# push rmtp://localhost/twitch; # Uncomment this to use application on localhost (MUST BE SPECIFIED). OR simply use the following line:
	# push rtmp://live-ams.twitch.tv/app /live_YOUR-LIVE-STREAM-KEY; # Your RTMP stream will be pushed as it is to Twitch as an RTMP stream.
