  • FFMPEG isn't working with scaling and multiple renditions on HLS

    22 mars 2018, par Gibojan

    I have an issue with ffmpeg and HLS. I want to have multiple renditions on my HLS stream.

    My source is a 1920x1080 stream from OBS. I have an EC2 AWS with nginx 1.13.1 and FFMPEG 2.8.11. Here is my code :

    application live {
    
    allow play all;
    
    live on;
    
    hls on;
    
    hls_nested on;
    
    hls_path /HLS/live;
    
    hls_fragment 10s;
    
    exec /usr/bin/ffmpeg -i rtmp://myAWSEC2/live/$name \
    
    -c:v libx264-s 640x360 -r 30 -b:v 800k -c:a copy -sws_flags fast_bilinear -f flv rtmp://myAWSEC2/mobile/$name_low \
    
    -c:v libx264-s 1280x720 -r 30 -b:v 2500k -c:a copy -sws_flags fast_bilinear -f flv rtmp://myAWSEC2/mobile/$name_high;
    
}
    

    
application mobile {
    
    allow play all;
    
    live on;
    
    hls on;
    
    hls_nested on;
    
    hls_path /HLS/mobile;
    
    hls_variant _low BANDWIDTH=1000000 RESOLUTION=640x360;
    
    hls_variant _low BANDWIDTH=2800000 RESOLUTION=1280x720;
    
}

    With that nginx.conf the application "live" works perfectly but the "mobile" don’t.

    If I don’t make any scaling with ffmeg, so with this command :

    exec /usr/bin/ffmpeg -i rtmp://myAWSEC2/live/$name \
    
    -c:v copy -c:a copy -f flv rtmp://myAWSEC2/mobile/$name_low \
    
    -c:v copy -c:a copy -f flv rtmp://myAWSEC2/mobile/$name_high;

    Both the "live" and "mobile" app are working. So I guess I give the wrong parameters to ffmeg command for scaling.

    My goal is to set different qualities for the video, keep the audio quality as maximum so the stream can be read by people with slow internet.

  • FFMPEG Conversion from GIF to video with audio, take too long

    5 novembre 2020, par Mouaad Abdelghafour AITALI

    I'm trying to convert a GIF file into 720p video and merge it with audio, the code below works fine, but it takes a long time to finish the process (depends on the audio length) :

    


    //Converting from GIF to video is fast!

public static String makeVideo(String inputGifPath, String outputPath, int width, int height) {
        return "-y -i " + inputGifPath + " -movflags faststart -pix_fmt yuv420p -vf crop=" + width + ":" + height + ":0:40,scale=1280:720,setsar=1 " + outputPath;
    }



//Merging video with audio takes a lot of time!

public static String addAudio(String audioNoSpace, String inputVideoPath, String outputVideoPath) {
    return "-stream_loop -1 -i " + inputVideoPath + " -i " + audioNoSpace + " -shortest -map 0:v:0 -map 1:a:0 -y " + outputVideoPath;
}


    


    FFMPEG commands :

    


    -y -i file.gif  -movflags faststart -pix_fmt yuv420p -vf crop=540:250:0:40,scale=1280:720,setsar=1 video.mp4

-stream_loop -1 -i video.mp4 -i  audio.wav -shortest -map 0:v:0 -map 1:a:0 -y final_video.mp4
