• 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"?>
  
  <mpd xmlns="urn:mpeg:dash:schema:mpd:2011" profiles="urn:mpeg:dash:profile:isoff-live:2011" type="dynamic" minimumupdateperiod="PT4S" suggestedpresentationdelay="PT4S" availabilitystarttime="2019-06-24T13:38:04Z" publishtime="2019-06-24T13:38:34Z" timeshiftbufferdepth="PT14.9S" minbuffertime="PT9.9S">

      </period>
  
  </mpd>

• ffmpeg ignore PUT and does POST when sending -f segment chunks [closed]

  5 novembre 2023, par l_-A-_l

  I cannot figure why ffmpeg does send chunck over PUT method when I use the -f dash (parameter) :

  


  ffmpeg -nostats -nostdin -i - -f dash -seg_duration 1 -window_size 10 extra_window_size 2 -remove_at_exit 1 -use_timeline 1 -dash_segment_type webm -c:a libvorbis -b:a 128k -method PUT http://nginx/test/main.mpd


  


  and refuses to PUT (and use POST instead) when I use -f segment :

  


  ffmpeg -i - -vn -acodec copy -f segment -segment_time 5 -method PUT  http://nginx/flux/segment_%3d.mp3


  


  (I need to use the PUT method)
