two pass encoding in ffmpeg
7 août 2015, par RobinI will be encoding different videos uploaded by the user asynchronously in my server. I saw this post, and according to this, this is how to endcode two pass encoding :
ffmpeg -y -i input -c:v libx264 -preset medium -b:v 555k -pass 1 -c:a libfdk_aac -b:a 128k -f mp4 /dev/null && \
ffmpeg -i input -c:v libx264 -preset medium -b:v 555k -pass 2 -c:a libfdk_aac -b:a 128k output.mp4I noticed the -pass 1 and -pass 2 flags. But I tried encoding a video by just giving it a -pass 2 flag without first encoding in -pass 1 flag. Although I had this warning, it executed anyway :
2nd pass has more frames than 1st pass
So, my concern is how will ffmpeg know which one is the first pass so that it can do its pass 2 encoding ? And since many videos will be uploaded simultaneously I can’t keep them all at the /dev/null won’t it will replace one with another. So how can I manage it ?
Your help and guidance will be very much appreciated.
Thank you.

ffmpeg cmd :
