Laravel FFMpeg - FFMpeg 无法就地编辑现有文件

Question

在我想在队列中上传视频后，返回了一个失败的作业。

 [2020-09-25 13:24:25][125] Processing: App\Jobs\ConvertVideoForStreaming <br /> [2020-09-25 13:24:26][125] Failed:     App\Jobs\ConvertVideoForStreaming

因此，我从数据库 failed_jobs 表中获取了响应并运行以下命令:

  C:\ffmpeg\bin\ffmpeg.exe -y -i "C:\wamp64\www\laravel-stream\storage\app/public\WF3UL8fJTSE7BMxa.mp4" -threads 12 -vcodec libx264 -acodec libmp3lame -b:v 500k -refs 6 -coder 1 -sc_threshold 40 -flags +loop -me_range 16 -subq 7 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4 -trellis 1 -b:a 128k -vf "[in]scale=720:360 [out]" -pass 1 -passlogfile "C:\Users\wlask\AppData\Local\Temp\ffmpeg-passes5f6dd36a4519fd1fev/pass-5f6dd36a452c9" "C:\wamp64\www\laravel-stream\storage\app/public\WF3UL8fJTSE7BMxa.mp4"

其中返回以下内容:

FFmpeg cannot edit existing files in-place.

这是在我从 DB failed jobs table return 运行命令后返回的。
我应该如何解决这个问题？

Answer 1

ffmpeg 无法编辑输入和输出在同一文件夹中的视频。
您必须在其他文件夹中配置视频输出。
