• FFMPEG : Fade the video out when ended

  21 septembre 2015, par kenicky

  In this link : https://trac.ffmpeg.org/wiki/Create%20a%20mosaic%20out%20of%20several%20input%20videos

  I tweaked the code they provided to end the encoding in a specific time.

  Now I wanted to fade out the video to black when it is ended.

  Thanks.

  While installing ffmpeg on Ubuntu 12.04

  I am getting following error

  Do anyone have idea about this error ?

• Trim video with reference to a start time and end time using FFMPEG

  8 février 2015, par Saty

  I am trying to do an application in which I would like to give option to user to clip a video using double seekbar so that video can be cropped.

  I had hassle importing FFmpeg into Eclipse. However, that pain is over, and I got two points of video and can instantiate FFmpeg’s instant.

  My focus is to know to know the method and procedure to crop a video.

  I got the command of cutting it, that is,

  ffmpeg -ss [start] -i in.mp4 -t [duration] -c:v copy -c:a copy out.mp4

  However, how do I use this in code ?
