• FFMPEG resizing ouputs 0B file

  26 octobre 2016, par Rahul Kumar

  I am trying to resize a .mp4 file to different resolutions.
  This is the command I’m using :

  /c E:\videos\manage\ffmpeg.exe -i "E:\media\SampleVideo1280x7201mb.mp4" -s 800x600 -ar 22050 "E:\media\encoded\med_SampleVideo1280x7201mb.mp4" 2>&1

  This works for most of the files but for some input files, the file that outputs is 0B in size and This is the message I get :

• How to insert infinite audio into the live streaming by using ffmpeg ?
