• tests/fate/source-check : Relax BSD licence check

  tests/fate/source-check : Relax BSD licence check
  Several files already had standard license header (namely
  
  2-clause BSD files), yet due to the 80 char line length limit,
  
  they were not treated as such by source-check.sh (which
  
  fate-source uses). Therefore relax the BSD check.

• GStreamer encountered a general stream error in Qt5 raspberry pi

  14 décembre 2016, par Myanju

  I’m trying to play a video using QtMediaPlayer in Raspberry pi 2 B. The source code is as follows :

  QMediaPlayer *media;
  
  QVideoWidget *video;
  
  ...
  
  ...
  
  media = new QMediaPlayer(parent);
  
  video = new QVideoWidget(parent);
  
  media->setVideoOutput(video);
  
  media->setMedia(QUrl::fromLocalFile("/home/pi/Desktop/test3.mp4"));
  
  media->play();

  But the result is a blank video screen and the following error :

  ** (Bus:2148): WARNING **: ffmpegcolorspace-vo: size 1105920 is not a   
  
  multiple of unit size 829440
  
  Error: "GStreamer encountered a general stream error."

  System Information

  Running latest raspbian Jessie OS,
  Installed Qt5.3,
  Installed gstreamer0.10-plugins-good/bad/ugly/ffmpeg and
  Installed Mpeg-2 License

  Here is the video test3.mp4

  I ran this code in Windows with Qt5 installed ; it is working there. But it’s not working in the Raspberry pi. Please tell me what I’m missing here.
