 -itsoffset 0^
 -i %%~na.mp3 -i cover.jpg^

• HTML5 Video plays on macOS safari, not iOS Safari

  8 février 2019, par BenJ

  Everything seems to work in Safari and Chrome on the desktop. But iOS is not cooperating.

  Here’s how I encoded the video :

  ffmpeg -an -i orig.mp4 -vcodec libx264 -crf 30 -maxrate 900 -pix_fmt yuv420p -profile:v baseline -level 3 homepage.mp4

  Here’s my html :

  <video playsinline="playsinline" muted="muted" autoplay="autoplay" loop="loop" src="/assets/videos/homepage.mp4" type="video/mp4"></video>

  Here’s my css :

  video { 
  
      position: fixed;
  
      top: 50%;
  
      left: 50%;
  
      min-width: 100%;
  
      min-height: 100%;
  
      width: auto;
  
      height: auto;
  
      z-index: -100;
  
      transform: translateX(-50%) translateY(-50%);
  
      background-size: cover;
  
      transition: 1s opacity;
  
  }

• Using Qt Media Player on Raspberry Pi 1

  18 mai 2015, par Mauker

  I have a project built using Qt5 which has to play a video. Just like in the videowidget sample code.

  I’ve followed these instructions to build qt5 on my Pi. And it went just fine. But when I try to run any qt program that uses QMediaPlayer, I get the error message :

  defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"

  Which means I don’t have a backend to play the video, right ? Is there any one that I can use which will with Qt, like ffmpeg ? And how can I get it to work ? Specially for h264 videos.

  I’ve tried to install gstreamer as is told on this link, but it’s not working. Will I have to rebuild the entire qt5 again ?

  P.S. : I have the raspberry pi 1 model B with raspbian installed.

  Edit : As mentioned by Greenflow, I checked the ./configure log and saw that the GStreamer was compiled in, but the video apps are still not working...

  The message on the log was like this :

  GStreamer .............. yes (0.10)

  And the message on Greenflow’s log was like this :

  GStreamer .............. yes (1.0)

  Clearly it’s another version of GStreamer, but is it the problem ?

  I’ve also found this post which says QtMultimedia on the Pi is rather useless, but the post is from 2013, so I’m not sure if it’s really relevant. I’d like to have this app playing hardware accelerated videos on my Raspberry Pi, but I’m almost dropping the idea.

  Anyways, thanks Greenflow for the head start.

  Edit 2 : Found this thread on the Qtcentre. Damn, this thing is not going to be easy to solve, I guess...
