  • Nginx + rtmp + ffmpeg best practice to publish multiple resolutions streaming from video file

    7 novembre 2019, par youssef hamdane

    I want to make livestream from video file to multiple resolutions (480,720) using nginx and rtmp, what is the best practice that I can do for that :

    1 - transcode video and store it with all resolutions that I need when user upload it using ffmpeg, and then publish every file directly

    example :

    rtmp {
    
    server {
    
        listen 1935;
    
        notify_method get;
    

    
        application live {
    
            live on; 
    
            ffmpeg -re -i /path/video_720.mp4
    
           -re -i /path/video_480.mp4
    
           -map 0 vcodec libx264 -threads 0 -vprofile baseline -acodec aac -strict -2 -f flv rtmp://localhost:1935/show/${name}_720
    
           -map 0 vcodec libx264 -threads 0 -vprofile baseline -acodec aac -strict -2 -f flv rtmp://localhost:1935/show/${name}_480
    
        }
    

    
       application show {
    

    
            live on;
    

    
            hls on;
    
            hls_path /stream/live/hls;
    
            hls_nested on;
    
            record off;
    

    
            # Instruct clients to adjust resolution according to bandwidth
    

    
            hls_variant _720 BANDWIDTH=2048000; # High bitrate, HD 720p resolution
    
            hls_variant _480 BANDWIDTH=448000; # Medium bitrate, SD resolution
    

    
        }
    

    
    }
    
}

    2 - keep original video and publish it on different resolutions with ffmpeg

    example :

    rtmp {
    
    server {
    
        listen 1935;
    
        notify_method get;
    

    
        application live {
    
            live on;     
    

    
            exec_pull ffmpeg -re -i http://server_ip/$app/$name -vcodec libx264 -threads 0 -vprofile baseline -acodec aac -strict -2 -b:v 1920k -b:a 128k -vf "scale=1280:trunc(ow/a/2)*2" -f flv rtmp://localhost:1935/show/${name}_720 
    
            -vcodec libx264 -threads 0 -vprofile baseline -acodec aac -strict -2 -b:v 1024k -b:a 128k -vf "scale=854:trunc(ow/a/2)*2" -f flv rtmp://localhost:1935/show/${name}_480;
    
        }
    

    
       application show {
    

    
            live on;
    

    
            hls on;
    
            hls_path /home/stream/live/hls;
    
            hls_nested on;
    
            record off;
    

    
            # Instruct clients to adjust resolution according to bandwidth
    

    
            hls_variant _720 BANDWIDTH=2048000; # High bitrate, HD 720p resolution
    
            hls_variant _480 BANDWIDTH=448000; # Medium bitrate, SD resolution
    

    
        }
    

    
    }
    
}

  • hevc transcoded video not playing in safari

    9 juin 2023, par zuccy

    I transcoded a video with ffmpeg to hevc using the below command.

    


    ffmpeg -i input.mp4 -c:v libx265 -crf 23 -preset medium -x265-params keyint=60 -c:a aac -b:a 128k -f hls -hls_time 10 -hls_segment_type fmp4 -hls_playlist_type vod -tag:v hvc1  -single_file 1 playlist.m3u8


    


    ffmpeg version : 5.0.1

    


    The output is playing fine in chrome but not in safari.

    


    I found from apple support community that fmp4 should work fine in safari. I tried with different tags, presets and x265 params but I can't make it work.

    


    I want the output to be hevc hls and it should be playable in safari and chrome. Any help is really appreciated.

    


  • HTML5 live streaming usin FFmpeg

    4 juin 2015, par user3149172

    I want to stream video from my IP camera (using RTSP) and use FFmpeg. I found example which looks like :

    ffmpeg -i rtsp://MY-IP/0 -y  -c:v libx264 -b:v 448k -vprofile baseline -preset medium -x264opts level=41 -threads 4 -s 1920x1080 -map 0:v -map 0:a:0  -c:a libfaac -b:a 160000 -ac 2 -hls_time 10-hls_list_size 6 -hls_wrap 18 -start_number 1 stream.m3u8

    and the html page :

        
    
        <video height="531" width="945" autoplay="autoplay" controls="controls">
    
            <source src="stream.m3u8"></source>
    
        </video>
    
    

    But there are the problems with mapping. While running the ffmpeg I get error :
    Stream map ’0:a:0’ matches no streams.
