• Recorded & uploaded video from iphone device won't play in iphone

  11 juin 2019, par Sohil Chamadia

  I am facing an issue regarding :

  Recording video from iphone and uploading that video on my application(Develop in Wordpress Framework) then the video uploaded won’t play in iphone devices.

  This issue occurs only when I "Record video from iphone and then uploading that video into the application".If I upload existing video from iphone device then video will be played and it’s working fine. So please help to resolve this issue.I have used "FFmpeg library" to reduce the size of video.

  Below is the code which i have used to play video :

  <video preload="auto" width="320" height="240" controls=""><source src="abc.mp4" type="video/mp4">Your browser does not support the video tag.</source></video>

  When i click on video to play it then video is not play and cross sign is shown over the play button.Below i have attached screenshot of it :
  

• Using FFMPEG to reliably convert videos to mp4 for iphone/ipod and flash players

  13 janvier 2023, par Jake Stevenson

  I need to convert videos for use in both a flash player and the iphone/ipod touch. I'm using the following batch script with ffmpeg :

  



  @echo off
ffmpeg.exe -i %1 -s qvga -acodec libfaac -ar 22050 -ab 128k -vcodec libx264 -threads 0 -f ipod %2


  



  This always outputs an mp4 file, and I can always play it on my PC. The videos also seem to play fine on my iphone 3GS. But with some input files it won't work for older iphone versions (3G and iPod touch).

  



  Here's the ffmpeg output from one such file :

  My suspicion is that it has something to do with the audio encoding. If so, does anyone know how to force it to reencode the audio to the proper format ?

  



  Any other ideas ?

  


• Serve media collection to an old iphone 3gs [on hold]

  25 février 2019, par Ale

  I’d like to serve a media collection, hosted in a home network, to an old iphone. I’m pretty much able to do this using apache web server, html, javascript, and jwplayer. But most of the media is in a format that the iphone doesn’t support and so I run into the problem of transcoding each movie I want to play but I would like it to happen on the fly to save time as well as be able to seek or fast forward to different parts of the movie. How can I go about doing this using the tools I already mention ? Php and ffmpeg are also welcome. Other tools are fine but please suggest open source if posible. I’m on a windows pc at this time. I’m sorry for not being too specific. I’m looking for a method or a different set of tools to point me in the right direction.

  Thanks in advance.
