• My (FFMPEG issue ) RTMP server(freebsd) wont let me hear video when I play a huge file over the server itself :/

  19 avril 2021, par Engi Gang

  Hey my name is Alisha from Norway im trying to get my RTMP server working the thing is that it works just fine but I just cant stream over it with ffmpeg I can stream to it on OBS and it works fine, but I am trying to a website where people could watch old public domain movies from the 1950 some of the films are actually pretty big lol.... anyways I detailed bellow more

  


  rm -rf /mnt/hls/loool && ffmpeg -re -i "$file" -c:v libx264 -c:a aac -b:v 300k -b:a 95k -f flv -flvflags no_duration_filesize rtmp ://lambright.xyz:1935/live/loool

  


  any work around I literally cant play the audio :( I can only hear (my source file is an MKV and 3gb )

  


  Note I had a smaller mp4 file and it did played the audio, the video isnt even playable in chrome but on VLC it is, but only a small file worked fine... its fine when I stream from my pc, but whats the point I am trying to set up my vintage 1950 serverbox :') trying to build a nice website where users could watch neat and decent old movies that are public domain if you wonder :/

  


  Another note when I am trying to play it on my iphone safari browser it does actually play parts but audio is super corrupted like you hear the audio sometimes :((

  


  rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000;

        application live {
            allow play all;
            live on;
            record off;
            hls on;
            hls_nested on;
            hls_path /mnt/hls/;
            hls_fragment 2s;
        }
        
    }
}


  


• How to transcode 50 H264 Streams with FFMPEG more efficient ?

  20 juin 2019, par Kevin

  i need to (Re-)Transcode 50 Live-Streams. These streams are in H264 with 720p to 1080p and bitrates up to 10M. I just want to reduce the quality and bitrate of the streams to up to 720p with max. 2M Bitrate.

  That’s what i’m doing right now :

  ffmpeg -re -i "http://domain.tld/path/file.ext" -vcodec libx264 -preset veryfast -vf scale=-2:720 -b:v 2M -maxrate 2M -bufsize 1M -acodec libfdk_aac -f flv "rtmp://127.0.0.1:1935/live/stream_xyz"

  My Server CPU (2 x Xeon E5-2630 v3) is already at 100% with just 12 streams. I will upgrade my server to 2 x Xeon Gold 5118 next month, but i don’t think, that this will give me that much more power.

  Can someone help me, to do this more efficient ?

  Would it be more efficient / cheaper to do this with GPUs ?

  Or any other ideas, to do that as efficient and cheap as possible ?

  Thanks
