• HTML5 video player doesn't work on iPad/iPhone

  16 avril 2015, par Avrohom Yisroel

  NOTE This turned out to be a simulator problem, not a video encoding problem, see my edit lower down...

  I’m creating a web site for a local college, and they want to be able to add short videos that people can view online. I’ve spent quite a bit of time trying to work out how to get the videos to play on iDevices, but have failed.

  I’m using Video.js (http://www.videojs.com), and have HTML that looks like this...

  <video class="video-js vjs-default-skin" controls="controls" preload="auto" width="640" height="352" poster="/Content/Images/logobg.png" data-setup="{}">
  
    <source src="/Content/Videos/video.m4v" type="video/mp4">
  
    <source src="/Content/Videos/video.webm" type="video/webm">
  
    <p class="vjs-no-js">
  
      To view this video please enable JavaScript, and consider upgrading to a web browser that <a href="http://videojs.com/html5-video-support/" target="_blank">supports HTML5 video</a>
  
    </p>
  
  </source></source></video>

  This works fine on desktop browsers, where it uses the m4v file. However, if I load the page on an iDevice, the video player says "no compatible source was found for this video", which sounds like it doesn’t like either the m4v or the webm file.

  I created the webm file using instructions found at http://daniemon.com/blog/how-to-convert-videos-to-webm-with-ffmpeg/. I tried creating a .mov file using the accepted answer at iPad Doesn’t Render H.264 Video with HTML5, but this gave the same error.

  Anyone any ideas how I can support iDevices ? Please don’t blind me with science, I’m a real newbie with all this video stuff, and need simple instructions !

  Edit The problem I was having was when trying to view the site on a mobile simulator. When I uploaded the site to a real server, and tried it on an iPad, it worked fine. So, if anyone is having a similar problem, first use something like Handbrake to encode the videos, as it seems to do it fine, then make sure you’re testing on a real mobile device, not a simulator !

• Use FFmpeg to replace audio in video in Android

  8 juin 2023, par Akari

  I come in trouble with replacing audio track in a video. I select a video from my gallery and I save that video in a file (video file), I also select a audio from my device and save it in a file (audio file). I use FFmpeg to replace audio track in file video select, but I get error, the message is empty and I don't have enough information to fix it. Please, help me !!! Thanks
