• Shaka Player : ignore empty AdaptationSet

  24 juin 2019, par Mitya

  I’m trying to play DASH stream in Shaka Player.
  Sometimes the stream doesn’t have an audio source and its manifest file contains an empty AdaptationSet entry.
  In this case Shaka Player returns the manifest parsing error :

  | DASH_EMPTY_ADAPTATION_SET | 4003 | number |  The DASH Manifest contained an AdaptationSet with no Representations. |

  Is it possible to ignore this error somehow and play the video without audio source ?

  Example of manifest file :

  <?xml version="1.0" encoding="utf-8"?>

  I am trying add some text on video, but I am getting :

  No such filter:
  
    Error initializing complex filters.
  
    Invalid argument

  Below command using for adding text -

  In Java :

  String complexCommand = "ffmpeg -i "+ savedVideoFilePath +" -filter_complex \"[0:v][1:v]overlay=10:10,drawtext=text="+"'"+ timestamp +"'" + "\""+ " -c:a copy -movflags +faststart " +output_path;

  In string format :
