Using ffmpeg to convert a list of files with timestamped filenames into an mpeg video
Change the line "for f in $( ls drone*.bmp ); do" to filter the images to be used - here "drone*.bmp"
The last filename in the ffmpeg line to the destination name.
#! /bin/bash mkdir -p tmp rm tmp/* let COUNTER=1000000 for f in $( ls drone*.bmp ); do echo convert $f tmp/path$COUNTER.png convert $f tmp/path$COUNTER.png let PREV=$COUNTER let COUNTER+=1 # use same image again to lower framerate convert $f tmp/path$COUNTER.png let PREV=$COUNTER let COUNTER+=1 done # convert to mpeg format # -r 25 frames per second # -b:v 5000000 video bitrate på 5Mbit/sec # -y betyder overskriv destination ffmpeg -y -i tmp/path1%06d.png -r 20 -b:v 5000000 r2raw4.mpeg ls -l *.mpeg
Save the modified file as e.g. "makempeg"
then make it runable and run it
chmod +x makempeg ./makempeg
