  • Name ffmpeg generated images using timestamp rather than sequential numbers

    15 décembre 2015, par weotch

    As far as I can tell from the ffmpeg docs, they don’t provide a way to use timestamps in the filename rather than sequential numbers. What they provide allows you to create 0001.jpg, 0002.jpg, 0003.jpg but not 2011-08-01 7:30:00.jpg, 2011-08-01 7:30:01.jpg, 2011-08-01 7:30:02.jpg. Can anyone think of a solution that could take the sequentially named files from ffmpeg and name them using their created time ?

  • FFMpeg SetSar value gets overriden

    8 décembre 2015, par user650922

    I have a video concatenating application where In all videos are converted to the same format .

    I am converting 640*360 video to 1080*720 with setsar=1:1 as

    ffmpeg -i C :\Users\work\Desktop\Esocializ\B.mp4 -s 1080*720 -ac 2 -vf setsar=1 :
    1 -acodec aac -strict experimental B1.mp4.

    However for some reasons its value get overridden.

    Any help would be appreciated .

    Below is my console output :

    C:\Users\work\Downloads\ffmpeg-20151130-git-7b11eea-win64-static\ffmpeg-20151130

  • Xuggler Error : Could Not Open

    22 septembre 2012, par MalTec

    I am using xuggler API to transcode Video from one format to another.

    Following the example, provided by

    public void convertVideo(){
    

    
     String sourceUrl=getResourceDirectory()+"/in/AV36_1.AVI";
    
     String destUrl=getResourceDirectory()+"/out/output.mp4";
    

    
     IMediaReader reader = ToolFactory.makeReader(sourceUrl);
    

    
        // add a viewer to the reader, to see progress as the media is
    
        // transcoded
    
        reader.addListener(ToolFactory.makeViewer(true));
    

    
     // create a writer which receives the decoded media from
    
     // reader, encodes it and writes it out to the specified file
    
     IMediaWriter writer = ToolFactory.makeWriter(destUrl, reader);
    

    
     // add a debug listener to the writer to see media writer events
    
     writer.addListener(ToolFactory.makeDebugListener());
    

    

    
////
    
////        // create the media writer
    
        reader.addListener(ToolFactory.makeWriter(destUrl, reader));
    

    
        // read packets from the source file, which dispatch events to the
    
        // writer, this will continue until 
    

    

    
        while (reader.readPacket() == null)
    
          do {} while(false);
    
    }

    Provides Could Not Open Exception :
