基于ffmpeg的视频工具
剪辑命令：ffmpeg -ss 00:00:22 -t 00:05:12 -i Sekiro20230826182243.webm -vcodec copy -acodec copy output2.webm 合并命令：ffmpeg -f concat -i list.txt -c copy concat.mp4
防止2压：ffmpeg -i src.webm -c:v libx264 -vf zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=tonemap=hable:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p out.mp4
