• FFmpeg converting image sequence to video results in blank video [closed]

  11 septembre 2016, par Brandon Durham

  I’ve got a series of 361 .png files that I’m trying to convert to video, and for whatever reason the resulting video is just black. Here is the FFmpeg code I’m using :

  ffmpeg -f image2 -i "FeatureTour_%05d.png" -r 30 -vcodec libx264 -b:v 9600k "FeatureTour.mp4"

  The files are formatted correctly (FeatureTour_00001.png) and no errors are thrown. It just results in a 160kb mp4 files that’s black.

  Any idea what I’m doing wrong ?

  EDIT

  Here is my output after using the above code :

• ffmpeg fastest way to convert videos avi to mp4 [migrated]

  5 novembre 2013, par user2938660

  I have server which has :

  • 8x3,4 (sandy bridge cpu)
  • 10gb ram

  i tried different combinations to convert vvideos i mean avi to mp4 but it takes so long :
  - 20mins= 200mb

  maybe there is some ffmpeg command which does this much faster ?

• FFMPEG on ubuntu wont start. Process is just killed [on hold]

  8 novembre 2018, par AK47

  I am trying to run a command on ffmpeg. When I run on my local computer it works fine but when running on my ubuntu server it won’t start. It just keeps giving an error saying the process is killed when it trys to start. Is this something related to memory or a different issue ?

  Killed   14 fps=0.0 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A dup=2 drop=0 speed=   0x

  Any help would be greatly appreciated
