  • Want to send a video from desktop to Wowza using ffmpeg

    3 mars 2018, par ST94

    I am trying to stream a local .mp4 video file from my laptop to Wowza Streaming Engine using ffmpeg. Both systems are able to ping each other. I give the following command on my laptop

    ffmpeg -re -i bunny_1080p_60fps_normal.mp4 -vcodec libx264 -acodec aac -ar 48000 -strict experimental -f flv "rtmp://192.168.1.22:1935/live/myStream"

    192.168.1.22 is the IP address of Wowza server residing on another system running Ubuntu 17.04.

    I see the following on the command prompt of my laptop when I give the above command,

    Can anyone please tell me what the exact procedure is to stream a video file to Wowza .

    How will I be able to view the stream at Wowza ?

  • Why does FFMPEG report the wrong duration ?

    7 janvier 2020, par Adrian Lynch

    I have an oldish build of FFmpeg that I can’t easily change.

    We use FFmpeg to find the duration of video and sound files. So far it has been working wonderfully.

    Recently on an uploaded file, FFmpeg has reported a 30 second file as being 5 minutes 30 seconds in length.

    Could it be something wrong with the file rather than FFmpeg ?

    If I use FFmpeg to convert to another file, the duration is restored.

    In case it matters, ffmpeg -i ’path to the file’ produces :

    Stream #0.1(eng) : Video : h264, yuv420p, 720x576, 25.00 tb(r)
Must supply at least one output file

    It’s that very command I use to then extract the duration with RegEx.

    Does anyone have a nice application that can do what I’m trying above but get it right 100% of the time ?

  • ffmpeg extracting frames from video

    22 novembre 2017, par TheOtherguyz4kj

    I am using Writingminds FFmpeg to use FFmpeg with Android. I am currently trying to extract frames from a video.

    I would like to extract 8 frames from the video evenly distributed throughout the video. I found this tutorial here is my implementation of it.

    MediaMetadataRetriever retriever = new MediaMetadataRetriever();
    
    retriever.setDataSource(videoCroppedFile.getAbsolutePath());
    
    String time = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
    
    Long videoLength = Long.parseLong(time);
    

    

    
final String cmd[] = {
    

    
            "-i",
    
            videoCroppedFile.getAbsolutePath(),
    
            "-f",
    
            "image2",
    
            "-ss",
    
            String.valueOf(videoLength.intValue() / ((8 + 1) * 10)),
    
            "-r",
    
            String.valueOf((8 + 1) / videoLength.intValue()),
    
            mediaStorageDir.getAbsolutePath() + "/%d.jpg"
    
    };

    However, when i go to the folder where the frames should be saved there isn’t anything there. Also there are no error messages.

    I feel like its a way this library takes the String parameters. I’ve been stuck on this for sometime I have tried lots of different versions of the cmd. I was hoping someone could help.

    Here is my output from ffmpeg :

    Update 3

    I fixed my code by doing :

     final String cmd[] = {
    

    
            "-i",
    
            videoCroppedFile.getAbsolutePath(),
    
            "-f",
    
            "image2",
    
            "-ss",
    
            String.valueOf(videoLength.floatValue() / (8.0  * 10.0)),
    
            "-r",
    
            String.valueOf(8.0 / videoLength.floatValue()),
    
            mediaStorageDir.getAbsolutePath() + "/%d.jpg"
