    I got this mod file from the Nintendo DSi + Internet Video (by dumping it with godmode9i and getting the mod file using godmode9). Any help is appreciated.

    


  • Nginx RTMP module to generate HLS

    28 novembre 2020, par Joe Lin

    I'm streaming an audio stream with opus codec from Kurento
via ffmpeg to nginx-rtmp-module. I'm using the below command to stream to nginx-rtmp :

    


    ffmpeg -protocol_whitelist file,udp,rtp  -i test-audio.sdp  
-c:a libopus  -f opus rtmp:///live/


    


    I see no error on the ffmpeg side. But there's no m3u8 file being generated. But I noticed the following in the nginx log :

    


    2020/11/23 23:19:31 [info] 95#0: *8 connect: app='live' args='' flashver='FMLE/3.0 (compatible; Lavf57.83' swf_url='' tc_url='rtmp://192.168.4.28:1935/live' page_url='' acodecs=0 vcodecs=0 object_encoding=0, client: 172.17.0.1, server: 0.0.0.0:1935


    


    Noticed the acodes=0. Does this mean that it doesn't like opus codec ?

    


    Below is my nginx.conf :

    


    rtmp {
    server {
        listen 1935;
        chunk_size 4096;
        application hopefm {
            live on;
            interleave on;

            hls on;
            hls_path /mnt/hls;
            hls_fragment 3;
            hls_playlist_length 60;
        }
    }
}


    


    Thanks for any help.
