这是我在脚本中的 ffmpeg 调用：
ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD128 \
-i "_$v" -i /home/john/Web/blackblog/_meta/graphics/watermark.png \
-filter_complex "[0:v][1:v] overlay_vaapi=25:25" -pix_fmt yuv420p \
-hide_banner -vcodec h264 -acodec aac "$filename.mp4"
它抛出这个错误：

当我从第一行删除所有参数时，它可以工作，但速度非常慢。当我打开硬件加速时，它给了我这个错误。我在 Arch linux 上运行它，这是以下输出ffmpeg -version：
