我正在嘗試從多個影像（由輸入檔案 test_matter_power_xxx.dat 的圖生成）中制作一個小影片。
這里的腳本：
#!/bin/bash
for i in {1..398}; do
gnuplot -p <<-EOFMarker
set terminal jpeg;
set logscale x;
set title "Matter Abgular power spectrum";
set xlabel "scale (k)";
set ylabel "P(k)";
set key top left;
set grid;
set ytics out nomirror;
set xtics out nomirror;
set logscale x;
set format x "10^{%L}";
set yrange [0:30000];
plot "test_matterpower_$i.dat" u 1:2 w l > pic$i.jpeg;
EOFMarker
done
# Build movie with ffmpeg
ffmpeg -start_number 1 -i pic%d.jpeg movie.mpeg
但我在執行時得到以下輸出：
./script_movie_gnuplot.sh
????JFIF``??;CREATOR: gd-jpeg v1.0 (using IJG JPEG v90), quality = 90
