FFMPEG on ubuntu wont start. Process is just killed [on hold]
8 novembre 2018, par AK47I 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 ?

Any help would be greatly appreciated

FFmpeg converting image sequence to video results in blank video [closed]
11 septembre 2016, par Brandon DurhamI’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 :
