使用命令：
ffmpeg -i in.mp4 -ss 00:01:10 -to 00:01:20 -q:v 2 -loop 0 “out.gif”
之前在网上找到一个命令是
ffmpeg -i in.mp4 -ss 00:01:10 -to 00:01:20 -vf “fps=10,scale=320
flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse;” -q:v 2 -loop 0 “out.gif”
此时不花了，原本运行没问题，电脑重装后，提示错误：
[AVFilterGraph @ 000001d4374ede40] No such filter: ‘’
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0

求助！！
