I am streaming RTMP via ffmpeg (also happens with avconv) on a raspberry pi and it randomly stops working after a few hours. Using the nginx-rtmp-module as the server.
There are no ffmpeg or avconv errors, it simply stops encoding new frames from the source webcam. After killing / and starting back up ffmpeg it works fine again.
Example ffmpeg command:
ffmpeg -nostdin -hide_banner -input_format yuyv422 -f video4linux2 -s 800x600 -r 15 -i /dev/video0 -c:v h264_omx -r 15 -b:v 1500k -g 30 -an -f flv rtmp://localhost:1935/live/stream
This is on Raspbian GNU/Linux 10 (buster) and has been seen on both Pi 3B+ and Zero W using 3 different webcams. Happens with either single or multiple webcams being used at a time. Have also tried -threads 1 to no effect.
Nginx config just in case:
worker_processes 1;
events {
worker_connections 1024;
}
rtmp_auto_push off;
rtmp {
server {
listen 1935;
chunk_size 4096;
application live {
live on;
record off;
allow publish 127.0.0.1;
deny publish all;
allow play 192.168.1.0/24;
deny play all;
}
}
}
Thanks for any suggestions!
Edit: Very minimal logs

1Right, run the command in my last comment and share its full log. – Gyan – 2019-07-28T16:14:25.197
Got ya now, I will let this run until it also stalls and report back! – CasualDemon – 2019-07-28T16:25:26.020
@Gyan stopped again and added log to post, sadly doesn't show any errors or additional stuff. – CasualDemon – 2019-07-29T02:15:27.673
I don't see the full log. – Gyan – 2019-07-29T04:40:22.197
I only copied what was visible when it stalled, copied the start of it as well this time. @Gyan – CasualDemon – 2019-07-29T19:00:37.420
