Slow motion/Fast Motion Videos made with Ffmpeg not getting played in Android 9.0 Pie

[karanatwal]

I have some videos on which i have applied slow/fast motion using below command(for slow) -

public String slowMo(String starttime, String endtime, String input, String output) {
       return "-i " + input + " -preset ultrafast -filter_complex " +
               "[0:v]trim=0:" + starttime + ",setpts=PTS-STARTPTS[v1];" +
               "[0:v]trim=" + starttime + ":" + endtime + ",setpts=PTS-STARTPTS[v2];" +
               "[0:v]trim=start=" + endtime + ",setpts=PTS-STARTPTS[v3];" +
               "[0:a]atrim=0:" + starttime + ",asetpts=PTS-STARTPTS[a1];" +
               "[0:a]atrim=" + starttime + ":" + endtime + ",asetpts=PTS-STARTPTS[a2];" +
               "[0:a]atrim=start=" + endtime + ",asetpts=PTS-STARTPTS[a3];" +
               "[v2]setpts=PTS/0.75[slowv];" +
               "[a2]atempo=0.75[slowa];" +
               "[v1][a1][slowv][slowa][v3][a3]concat=n=3:v=1:a=1[v][a]" +
               " -map [v] -map [a] -x264opts keyint=20:min-keyint=20:scenecut=-1 " + output;
   }

Videos made using above command are getting played in native player on Android 9.0 but not in your mediaplayer. I have checked in Oreo and Nougat they are working fine. Getting below in logcat.-
