    any idea why the generated video does not contain the subtitle ?

    


    Update

    


    Based on below comment , I changed my code to use the latest ffmpeg-kit version , here is the new code

    


    String cmd = "-i " + videoPath + " -vf subtitles=\"" + subtitlePAth + ":force_style='Alignment=10,Fontsize=18\" " + 
   outputVideoPath;

   FFmpegKit.executeAsync(cmd, new FFmpegSessionCompleteCallback() {

        @Override
        public void apply(FFmpegSession session) {

        }
    }, new LogCallback() {

        @Override
        public void apply(com.arthenica.ffmpegkit.Log log) {


        }
    }, new StatisticsCallback() {

        @Override
        public void apply(Statistics statistics) {              

        }
    });`


    


    and here is the updated log

  • ffmpeg not returning anything on Dash

    I am trying to extract subtitles from an MPD, but ffmpeg is not returning anything. If I try first a simple command such as :

    


    ffmpeg -i Downloads\Manifest.mpd


    


    After just 2 seconds it stops. This is the log :

    So basically, it did nothing. I have libxml2 installed and I am confused since there is no error at all. Any help ? Thank you !

    


  • ffmpeg concat "demuxer" doesn't concatenate videos with the same codec correctly [duplicate]

    the clips add up to about 27 secs but the output file is about 24 min long. the first clip runs normally but as soon as the second starts it just sorta freezes (it runs on an extremely low frame rate). the 3rd one just runs extremely fast for some reason.

    


    files.txt :

    


    file './tmp/clip_0_0.mp4' 
file './tmp/clip_0_1.mp4' 
file './tmp/clip_0_2.mp4' 


    


    this is the command I'm using

    


    ffmpeg -f concat -safe 0 -i files.txt -c copy -an ./ready/clip_0r.mp4

    


    files

    


    per request of llogan ; showing the output of ffmpeg -i ./tmp/clip_0_0.mp4 -i ./tmp/clip_0_1.mp4 -i ./tmp/clip_0_2.mp4
