    Im trying to trans code a mp4 file using the following command using a ffmpeg static build

    ./ffmpeg -i /tmp/tools/file_example.mp4 -map 0 -map 0 -map 0 -map 0 -c:v libx265 -f dash \
    
-b:v:0 25M -b:v:1 15M -b:v:2 6M -b:v:3 1M -maxrate 25M -bufsize 1835k -s:v:0 3840x2160 \
    
-s:v:1 3840x2160 -s:v:2 1920x1080 -s:v:3 1920x1080 -keyint_min 150 -g 150 \ /tmp/tools/example/4k.mpd

    On executing the command im getting the following exception

     ./ffmpeg -i /tmp/tools/file_example.mp4 -map 0 -map 0 -map 0 -map 0 -c:v libx265 -f dash -b:v:0 25M -b:v:1 15M -b:v:2 6M -b:v:3 1M -maxrate 25M -bufsize 1835k -s:v:0 3840x2160 -s:v:1 3840x2160 -s:v:2 1920x1080 -s:v:3 1920x1080 -keyint_min 150 -g 150 \ /tmp/tools/example/
