[Flutter] 相同的 FFmpeg 命令,命令行中运行很快, Flutter 中运行巨慢,如何 Debug?

发表于

就是一个简单的图片加水印任务:

ffmpeg -hide_banner -y -i image.AVIF -i watermark.png -filter_complex "overlay=(main_w-overlay_w-50):(main_h-overlay_h-50)" output.AVIF

命令行中运行几乎秒完成,但在 Flutter 中几乎要半分钟。

await Process.run('ffmpeg', [
    '-hide_banner',
    '-y',
    '-i',
    'image.AVIF',
    '-i',
    'watermark.png',
    '-filter_complex',
    'overlay=(main_w-overlay_w-50):(main_h-overlay_h-50)',
    'output.AVIF',
]);

整了一天了,完全没有头绪,求教,求教
