  • FFMPEG does not add images to audio

    20 février 2018, par Googlebot

    I want to create a slideshow with a background music by ffmpeg, and use the command

    ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

    and map.txt is like

    file '1.jpg'
    
duration 15
    
file '2.jpg'
    
duration 60

    The result is a video with the audio and blank background. If I run the above command without audio as

    ffmpeg -f concat -safe 0 -i map.txt -pix_fmt yuv420p -strict -2 video.mp4

    a perfect video of the images (the intended slideshow) is generated (but obviously without audio).

    I reckon the problem is related to synchronising the audio and images.

    This is the terminal output for the first command

    ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

  • How can I get audio in my ffmpeg stream to nginx rtmp server ?

    26 novembre 2013, par Conor Patrick

    I currently have a nginx server setup with the rtmp plugin for video streaming. I'm streaming to it with ffmpeg and then displaying the stream on a web browser with adobe flash player.

    I have the video streaming successfully but I have not been able to get audio.

    This is the ffmpeg command I use to start the stream

    ffmpeg -f video4linux2 -s 320x240 -r 16 -i /dev/video0 -f alsa -i hw:0 -an -f flv rtmp://123.456.789.51:31002/rover/mystream

    The stream then goes to nginx which is running on this conf file

    worker_processes  1;
    

    
error_log  logs/user/error.log debug;
    

    
events {

        location /stat.xsl {
    
            root nginx-rtmp-module-master/;
    
        }
    

    
        location /control {
    
            rtmp_control all;
    
        }
    

    
        #location /publish {
    
        #    return 201;
    
        #}
    

    
        #location /play {
    
        #    return 202;
    
        #}
    

    
        #location /record_done {
    
        #    return 203;
    
        #}
    

    
        location /rtmp-publisher {
    
            root /path/to/test;

            root nginx-rtmp-module-master/test/www;
    
        }
    
    }
    
}

    I then access the stream from a browser using this set up for the adobe flash player and strobe media player.

        
    
    
    
    
    
    
    
    
    
    
    
    

    Could I get some suggestions as to how I couldn't be getting audio ? I'm streaming video from my webcam and specifying audio from my mic.

  • ffmpeg : unsync audio after processing

    18 novembre 2013, par QuickSilver

    I am recording a video and using RecordRTC : WebRTC . After receiving the webm video and wav audio at server, I'm encoding it to a mp4 file using ffmpeg(executing shell command via php). But after encoding process, the audio is unsync with video (audio ends before video). How can I fix this ?

    js code is here

    ffmpeg command used is :

    ffmpeg -y -i 166890589.wav -i 166890589.webm -vcodec libx264 166890589.mp4
