the command I use to encode:
ffmpeg -y -i VideoCapture.mp4 -c:v libx264 -b:v 444k -pass 1 -an -f null /dev/null && \
ffmpeg -i VideoCapture.mp4 -c:v libx264 -b:v 444k -pass 2 -c:a aac -b:a 128k output.mp4
I took this code from the official ffmpeg documentation, by changing the audio and video bitrate values according to the examples in the documentation. This code error when I run it on Linux.
The above code can run on windows (by changing the characters "NULL" and "").
This is the full output of the error:

Why this happened? is there any solution for this problem?
thank you.
