• Video Compression Options [on hold]

  29 septembre 2019, par Rahul

  We want to add video compression library or framework for Android. We tried FFMPEG and Video Compressor Library but they are not good in following case.

  FFMPEG :

  • Works good for small video like 100 to 150 MB but it takes more time than 3 mins to Compress 1 to 2 GB Video.
  • Also used FFMPEG with x264 but didn’t work

  Video Compressor :

  • It has similar problem as FFMPEG as well as not works with different video container like .flv, .mkv

  We are also looking for any native code and algorithm (c & c++) and Open CV.

  Please suggest any other options by which we can achieve Video Compression like Facebook or WhatsApp
