  18 juin 2013, par AaronJiang

  I want to convert videos on my server using command line, maily mp4 -> flv or flv -> mp4. I googled and found these two products 'ffmpeg' and 'HandBrake cli'.

  https://trac.handbrake.fr/wiki/CLIGuide

  Which one is better ?

  Plus I am running on ubuntu server.

• iOS Recorded Video Playback on Android

  1er mars 2015, par Nirav

  I am trying to record video from iPhone device using UIImagePickerController and able to store it in MP4 format. The same video is uploaded on the Amazon S3 cloud.

  When I try to play the same video on Android devices, it fails to play with an error, cannot play.

  I searched forums/google and found that ffmpeg should be used to compress the video before uploading. I want to do the compression on the phone itself rather than on the server. Which is the best way to achieve this ?
