  • FFmpeg error : ratecontrol_init : can't open stats file

    6 octobre 2017, par oldo.nicho

    I’ve setup an AWS EC2 instance running Ubuntu 14.04 and have installed FFmpeg so that I can compress and transcode video.

    I’m trying to do a two pass conversion with the following code :

    ffmpeg -i input-file.avi -codec:v libx264 -profile:v high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=702:-1 -threads 0 -pass 1 -an -f mp4 ~/encoded/null

    and second pass :

    ffmpeg -i input-file.avi -codec:v libx264 -profile:v high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=702:-1 -threads 0 -pass 2 -codec:a libfdk_aac -b:a 128k -f mp4 output-file.mp4

    However I get the following error :

    The command as written above works fine on my local computer (running OSX). Would anyone have any suggestions as to how to fix this problem ?

  • Use FFmpeg concat two video, is output video level mistake ?
