我有一部需要更改速度并添加水印的视频
"[-y, -i, /storage/3665-3031/DCIM/Camera/VID_20200821_195124.mp4, -i, /storage/emulated/0/FXMotion/.cache/.watermark/logo_watermark.png, -filter_complex, [1:v]scale=1920/4:-1[logo1];[0:v]trim=0.0:135.869,setpts=0.3125*(PTS-STARTPTS)[v2];[0:a]atrim=0.0:135.869,asetpts=PTS-STARTPTS,atempo=2.0,atempo=1.600000023841858[a2];[v2][a2]concat=n=1:v=1:a=1[video];[video][logo1]overlay=main_w-overlay_w-10:main_h-overlay_h-10[vw], -map, [vw], -c:v, libx264, -c:a, aac, -crf, 18, -preset, veryfast, /storage/emulated/0/FXMotion/FXMotion-200821a.mp4, -hide_banner]"
但是，当我运行上面的命令时，它得到了下面的错误，我尝试在google上搜索，但没有解决问题， 如何解决这个错误？ ，谢谢。
