Double check you have a semicolon trailing your ffmpeg command, and that you supply the full path to the ffmpeg binary in your exec.

Using following rtmp block https://paste.ngx.cc/aa, the exec command to run ffmpeg to transcode the stream seemingly does nothing. I might have made a mistake in the configuration, but I'm attempting to take the input from the application livestream, transcode the stream to lower quality, and then push to twitch. FFmpeg doesn't seem to even be started as I've tried using redirects to get an output to go to a file, but the file doesn't get created and there is no evidence of the ffmpeg process running on the system.

Confirmed, full path being supplied makes no difference. Semicolon is definitely there as nginx wouldn't load the config otherwise.
What's showing up in your access and error log? Any sight of exec being fired?

Sorry for the delayed response. It seems running exec does not fire ffmpeg at all. No mention of this being made in either the access or error log whatsoever. I am at a loss of ideas to why it isn't working and thinking of instead just hammering out a shell script to fire ffmpeg and output to a separate app when the PUBLISH notification to 'livestream' in access.log is fired. However this is super messy and would prefer to try and get exec to fire ffmpeg.
EDIT: my mistake, PUBLISH log only is shown when stream ends. Need a way to know when the stream starts to fire automatically.
Hello, I don't know if you have solved your problem but in my case i did it by adding absolute path off ffmpeg command
application src {
live on;
exec /usr/local/bin/ffmpeg -i rtmp://localhost:1935/src/$name
-c copy -b 128K -f flv rtmp://localhost:1935/hls/$name_low
-c copy -b 256k -f flv rtmp://localhost:1935/hls/$name_mid
-c copy -b 512K -f flv rtmp://localhost:1935/hls/$name_hi
-c copy -f flv rtmp://localhost:1935/dash/$name;
allow publish 127.0.0.1;
deny publish all;
}
Hope this will help you
