Basically i do exec to transcode and push a stream to another server. The transcoding and video are fine everything works. When i lunch my exec from command line i have no errors at all. That is why i don't understand why this message is repeating all the time in my log.

[arut]

The message means ffmpeg exit.

[sulphur]

yeah but when i run the same command from command line it isn't exiting. well anyways it was more for your information since the video and transcoding are working fine.

[izemize]

Check your ffmpeg parameters with ps auxw| grep ffmpeg

ffmpeg is killed by nginx when publisher exits, that's normal. If everything works ok then just ignore that log line.

FYI for others encountering a similar issue, you might want to make sure that the nobody user has access to the device or file you're trying to read with ffmpeg. Try out your ffmpeg command with sudo -u nobody ffmpeg ARGS and see if it works first

Had the same issue. renaming exec => exec_push in nginx.conf helped. Works in nginx 1.15.1

[bundyfx]

Had this also, from the command line you are probably using '\' to separate long commands over many lines, you need to remove those before copying the command line command into your nginx.conf
