使用Golang拼接ffmpeg命令之后filter错误

Question

使用Golang拼接ffmpeg命令之后执行错误

直接在powershell中能执行成功

相关代码

cmd := exec.Command("cmd", "/C", `ffmpeg -i test.mp4  -filter_complex "movie=youku.png[watermark];[watermark]overlay=10:10;" test1.mp4`)

错误信息

[AVFilterGraph @ 000001786d433e00] No such filter: '"movie'
Error initializing complex filters.

已解决：把参数名用单引号引起来（双引号未测试）

cmd := exec.Command("cmd", "/C", `ffmpeg -i test.mp4 -filter_complex [0:v]'scale'=-2:480[scale];'movie'=youku.png[watermark];[scale][watermark]'overlay'=10:10 test1.mp4`)

这样即可，把参数名用单引号引起来（双引号未测试）

cmd := exec.Command("cmd", "/C", `ffmpeg -i test.mp4 -filter_complex [0:v]'scale'=-2:480[scale];'movie'=youku.png[watermark];[scale][watermark]'overlay'=10:10 test1.mp4`)
