  • ffmpeg posting to nginx hangs after 90 minutes

    22 octobre 2018, par Harnek Gulati

    I’m using a very simple program to push an ffmpeg stream from my raspberry pi camera to a nginx server. However, it fails after 90 minutes, with almost every single Raspberry Pi I use (I have this code on 12 Raspberry Pis).
    Here is my ffmpeg command :

    raspivid -o - -t 0 -w 640 -h 480 -fps 25 | ffmpeg -re -i - -vcodec copy -hls_time 4 -f hls -hls_list_size 5 -hls_wrap 5 -threads 0  -timeout 5000 -max_reload 20000 -method PUT http://{}:{}/live/{}

    And here is my configuration for nginx.conf :

    #user nobody;
    
load_module /usr/lib/nginx/modules/ndk_http_module.so;
    
load_module /usr/lib/nginx/modules/ngx_http_lua_module.so;
    

    
worker_processes auto;
    
env CONTROL_SERVER_IP;
    

    

    
#error_log /var/log/nginx/error.log;
    
error_log /dev/stdout info;

    worker_connections 1024;

            types {

            # Disable Cache
    
            add_header Cache-Control no-cache;
    
            include cors.conf;
    
  }
    
  }
    
}
    

    
daemon off;

    If anyone can help me, I would deeply appreciate it. I’ve been pulling my hair out trying to figure out this bug. On the raspberry pi, it hangs on this :

    And on the nginx logs, I get :

    I need to set up a way to either a) keep consistent connections longer than 90 minutes or b) detect when the 408 error happens and stop it from hanging.

  • Streaming low latency video

    26 août 2018, par user4893295

    Goal is to get low latency HD video over the LAN from a USB camera on a ARM device (a10 Lime running Armbian Jessie) to OBS Studio.

    Thinking first step is to at least get it viewable on VLC on another device. So, to that end, I have tried gstreamer (no joy), ffmpeg (same) and VLC. Best luck with VLC so far, but the picture is mostly blank with occasional spots of picture.

    This is the command I’m using :

    cvlc v4l2:///dev/video0:chroma=h264:width=1920:height=1080 --sout '#standard{access=http,mux=ts,dst=0.0.0.0:8080/stream,name=stream,mime=video/ts}' -vvv

    It moans a bit at first with

    [00b4a178] core interface error: no suitable interface module
    
[00ab18f8] core libvlc error: interface "globalhotkeys,none" initialization failed
    
[00b4a178] core interface debug: looking for interface module matching "dbus,none": 18 candidates

[00b4a178] core interface error: no suitable interface module
    
[00ab18f8] core libvlc error: interface "dbus,none" initialization failed

    But then seems to get a bit happier

[b4300508] core input debug: Stream buffering done (332 ms in 331 ms)
    
[b4300508] core input debug: Decoder wait done in 0 ms

    And I can connect to it from VLC, but the picture looks like

    enter image description here

    Processor peaks at around 17% and memory even less than that, so it’s not that.

    Any suggestions ?
