    avformat/dashenc: Enable dash output to work when the output isn’t a local file

    Use avpriv_io_move instead of ff_rename to support more than only
    
the file protocol.

  • Segment duration variation is higher than the +/- 50% allowed by DASH-IF

    23 March 2016, by timhysniu

    I am implement a proof of concept page with video player that uses DASH. I am having a difficult time getting the video right and I am not sure whether this is an encoding issue or MP4Box issue.

    Since I am working on Ubuntu I had to change a few parameters for ffmpeg, but according to what I read this should be fine:

    ~/ffmpeg/ffmpeg -c:a aac -ar 44100 -ac 1 -codec:v libx264 \
    
  -profile:v baseline -level 13 -b:v 2000k video_transcoded.mp4 -i video.mp4

    Then to create the MPD I am running this:

    MP4Box -dash 10000 -dash-profile live \
    
  -segment-name video_transcoded video_transcoded.mp4

    I am getting this response at the end, which might be why no player will play my video:

      [DASH] two languages in adaptation set: und will be kept eng will be ignored
    
  DASHing file video_transcoded.mp4
    
  [DASH]: Segment duration variation is higher than the  50% allowed by DASH-IF (min 1.044, max 10.448) - please reconsider encoding

    Here is the output of ffmpeg:
