The following is a little bit better:
    ffmpeg -y                       \
       -ss ${startTime}             \
       -to ${endTime}               \
       -i ${inputFile}              \
       -map_metadata -1             \
       -map_chapters -1             \
       -metadata title="${title}"   \
       -acodec copy                 \
       -vcodec libx264 -crf 26      \
       -pix_fmt yuv420p             \
       -preset veryfast             \
       ${outputFile}

Some people could not play it and I also wanted to add a title.
